The project can be started at any place but it is always. 2 Gas welding unit. Obtained at the time of preparation of project profile and may vary.

I have a DD low profile gas block and was wondering, what are the chances of this thing coming loose? This is a fairly hard use rifle, and my only rifle.

It gets shot about 5k rds a year and is used as a home defense gun, shtf gun, etc. I DO NOT want the gas block loosening up, and im rather paranoid about it now because, before the DD clamp on gas block, i had a YHM clamp on gas block installed by spikes tactical. When i went to take the gas block off and install the new one, the screws on the yhm gas block were extremely easy to remove.

I highly doubt that spikes forgot to tighten down the screws properly, as they do good work. However, the rifle had less then 500 rds down the tube since the install, which has me worried. I tightened the shit out of the screws on the DD block and also used rockset on them, it seems pretty solid but, idk. My other option (more time consuming) is to get a Larue gas block and send the barrel off to ADCO to get it installed/pinned in place. I personally do not trust the clamp on gas blocks, however the ones that the set screws intersect the barrel like the original pin on FSBs in my experience are more stable. The vertical set screws do not intersect the barrel and are more prone to being moved if bumped hard potentially causing gas leaks and failure of the weapon to cycle. I am still a fan of the original colt style FSB, it is considered part of the barrel by the manufacturers and is solidly pinned in place.

I read an article in one of the gun rags written by Larry Vickers some time ago and he states almost the same sentiments that I hold, and went on to say that he doesn't consider any rifle with a clamp on block/fsb a serious tactical weapon. My personal thoughts are on a plinker it's a non issue, but if you intend to do some hard training and actually use the weapon for what it was designed for then anything that could compromise the gas system is a no go, no matter what marketing hype or how 'high speed' it looks. Vltor vst (this one has caught my interest, I am waiting for the pinned version to come out. The split ring designs seem better than the others and put a lot of clamping surface around the barrel, so with right attachment method I think for average joe use it would be fine. Im not worried about the thing rotating or getting bumped out of place, especially since its covered by a larue rail. Motherboard Manual Dell.

What im concerned with is the screws backing out. I know a good little shop down the street from where i shoot, i think ill have them spot weld the bolt to the gb, that will def. Erase any worries i have of the thing moving. If i have to get it off ill just cut it off and buy a new one.

I think welding the bolts will be the best thing to do at this point. I was looking at a pic of the dd gas block could you use different bolts with the shoulder and a extended head then you could safety wire the bolts together. Looked around a little bit a found this [first pic shows a flush mounted bolt with a hole drilled in it for a safety wire] Does it look like that would work on the bolts for the DD low profile gas block? If it could that would be better than welding it. With the ones with the vertical screws, drill a small dimple down the threaded hole into the barrel a small bit, put some rockset in and torque the screw in down into the dimple.

VLTOR guy mentioned that to me when I was at the SAR show last Dec (he did not mention the rockset but I believe did mention some thread locker). I don't think those screws are coming out or the gas blocking is rotating no matter what the abuse. E guns, mine is the DD block, which is a clamp and uses horizontal screws. I think i got it stayin in place though. I first rocksetted the screws and then tightened the piss out of them, i then cut slits in the gas block and bolt heads and filled them with JB weld.

I actually feel pretty rest assured now, especially with the jb weld. This should hold for, well, about ever probably. Just to be on the safe side though, before i slid the rail back on i used a sharpie to draw some locating marks, so if the screws do loosen, ill be able to see.

Yeah sorry, was just responding to general comments from others. I actually have the same one (DD) in my gun.

It was super tight to get on my barrel anyway. I should put witness marks on mine as well to watch in case anything comes out. I think I just red loctited my screws in and torqued them.

So far it has 3-4k rounds through it including a 3-day EAG/Pat Rogers class and a 2 day Vickers class plus practice and stuff and seems ok. I will watch it and see if and when it starts having a problem.

If you torque the crap out of those flat socket cap screws and then stake them, they will not back out on their own. I used red loc-tite and lots of elbow grease, then staked them with a nail set. They ain't going anywhere. +1 That was the fix my local gunsmith recommended for the Armalite clamp on gas blocks on my 20' A4's.He reinstalled the screws with rockset and then staked the blocks into the screws and back staked the screws into the blocks.No problems so far and I have a couple thousand rounds through one of the uppers already. This hole is how I lined the block up on my gas port after marking the port location before removing the original FSB After torquing down well and red loc-tite: Staking: Finished product: http://web.me.com/supermarkus/iWeb/Site/Noveske%20Afghan%20build_files/IMG_1654.jpg. Using standard Red Locktie or JB weld on a gas block is about as useful as using Elmers glue.

Both breakdown at temp bellow what a gas block reaches after a good amount of sustained fire. IE as seen in a carbine class. Your best bet for a clamp on gas block, if you are worried, is to use rockset and or staking.just like a gas key.

Something to keep in mind, make sure the gas block is made from the same (or as close to as possible) material as the barrel so that they both expand as the same rate. An aluminum gas bloc will expand more than a steel barrel, and when hot enough will loosen up no matter how you have the bolts fixed. Its been staked and rocksetted, i dont think its going anywhere.

Mine appears to be off center on the inside of my rail, however, when using a level, the flats on the side of the gb are perfectly perpendicular to the top rail which is in turn perfectly square with the rail on the upper reciever. It appears though that the upper portion of the gas block isnt perfectly symmetrical, and i know the bottom isnt anymore as i had to grind it, the bottom split though also appears to be off a little, which puzzles me, because if i move it slightly in either direction it looks like the gas tube is misaligned a little bit.

The outer city held until October 10 and the citadel until the 21st, when Unur surrendered upon a promise of safe passage. Unur himself was permitted to return to Damascus but Zengi slaughtered most of his men. In December, Zengi negotiated with Muhammad, offering to trade Baalbek or for Damascus, but Unur convinced the atabeg to refuse. Zengi strengthened its fortifications and bestowed the territory on his lieutenant, father of. Upon Zengi's assassination in 1146, Ayyub surrendered the territory to Unur, who was acting as regent for Muhammad's son.

It was granted to the eunuch, who also served as viceroy of Damascus. In December 1151, it was raided by the garrison of as a reprisal for its role in a Turcoman raid on Banyas. Following Ata's murder, his nephew, emir of the, ruled Baalbek.

He was forced to relinquish it to in 1154 after Ayyub had successfully intrigued against Abaq from his estates near Baalbek. Ayyub then administered the area from Damascus on Nur ad-Din's behalf.

Baalbek's citadel served as a jail for taken by the Zengids as. In 1171, these captives successfully overpowered their guards and took possession of the castle from its garrison.

Muslims from the surrounding area gathered, however, and entered the castle through a secret passageway shown to them by a local. The Crusaders were then massacred. Three major earthquakes occurred in the 12th century, in 1139, 1157, and 1170. The one in 1170 ruined Baalbek's walls and, though Nur ad-Din repaired them, his young heir was made to yield it to by a 4-month siege in 1174. Having taken control of Damascus on the invitation of its governor, Saladin rewarded him with the emirate of Baalbek following the in 1175., the young leper, came of age the next year, ending the Crusaders' treaty with Saladin.

His former regent,, raided the from the west in the summer, suffering a slight defeat at Ibn al-Muqaddam's hands. He was then joined by the main army, riding north under Baldwin and; they defeated Saladin's elder brother in August at and plundered Baalbek. Upon the deposition of for neglecting his duties in Damascus, however, he demanded his childhood home of Baalbek as compensation. Ibn al-Muqaddam did not consent and Saladin opted to invest the city in late 1178 to maintain peace within his own family.

An attempt to pledge fealty to the Christians at was ignored on behalf of an existing treaty with Saladin. The siege was maintained peacefully through the snows of winter, with Saladin waiting for the 'foolish' commander and his garrison of 'ignorant scum' to come to terms. Sometime in spring, Ibn al-Muqaddam yielded and Saladin accepted his terms, granting him,, and. The generosity quieted unrest among Saladin's vassals through the rest of his reign but led his enemies to attempt to take advantage of his presumed weakness. He did not permit Turan Shah to retain Baalbek very long, though, instructing him to lead the Egyptian troops returning home in 1179 and appointing him to a sinecure in. Baalbek was then granted to his nephew, whose family ruled it for the next half-century.

Later in the same year, however,, the of, defeated the Mongols and placed Baalbek under the rule of their emir in Damascus. Most of the city's still-extant fine mosque and fortress architecture dates to the reign of the sultan in the 1280s.

[ ] By the early 14th century, the was describing the city's 'large and strong fortress'. The revived settlement was again destroyed by a flood on 10 May 1318, when water from the east and northeast made holes 30 m (98 ft) wide in walls 4 m (13 ft) thick. 194 people were killed and 1500 houses, 131 shops, 44 orchards, 17 ovens, 11 mills, and 4 aqueducts were ruined, along with the town's mosque and 13 other religious and educational buildings. In 1400, pillaged the town [ ] and there was further destruction from a 1459 earthquake. Uncovered in 2014 of and his wife passed through Baalbek on November 1, 1898, on his way to Jerusalem. He noted both the magnificence of the Roman remains and the drab condition of the modern settlement.

It was expected at the time that natural disasters, winter frosts, and the raiding of building materials by the city's residents would shortly ruin the remaining ruins. The archaeological team he dispatched began work within a month. Despite finding nothing they could date prior to Baalbek's occupation, and his associates worked until 1904 and produced a meticulously researched and thoroughly illustrated series of volumes. Later excavations under the Roman flagstones in the Great Court unearthed three and a fragment of pottery dated to the 6th–4th centuries BC. The featured letters. In 1977, made a brief study suggesting most of the large blocks could have been moved on rollers with using and blocks, a process which he theorised could use 512 workers to move a 557 tonnes (614 tons).

'Baalbek, with its colossal structures, is one of the finest examples of Imperial Roman architecture at its apogee', reported in making Baalbek a in 1984. When the committee inscribed the site, it expressed the wish that the protected area include the entire town within the Arab walls, as well as the southwestern extramural quarter between Bastan-al-Khan, the Roman site and the Mameluk mosque of Ras-al-Ain. Lebanon's representative gave assurances that the committee's wish would be honoured.

Recent cleaning operations at the Temple of Jupiter discovered the deep trench at its edge, whose study pushed back the date of Tell Baalbek's settlement to the. Finds included pottery including a spout dating to the early. In the summer of 2014, a team from the led by Jeanine Abdul Massih of the discovered a sixth, much larger stone suggested to be the.

The stone was found underneath and next to the Stone of the Pregnant Woman ('Hajjar al-Hibla') and measures around 19.6 m × 6 m × 5.5 m (64 ft × 20 ft × 18 ft). It is estimated to weigh 1,650 tonnes (1,820 tons).

20th century [ ]. A detail from a 1911 map of Turkey in Asia, showing Baalbek's former rail connections Baalbek was connected to the, the -owned railway concession in, on 19 June 1902. It formed a station on the line between to its south and (now in ) to its north.

This Aleppo Railway connected to the but—because that line was built to a 1.05-meter —all traffic had to be unloaded and reloaded at Riyaq. Just before the, the population was still around 5000, about 2000 each of and and 1000 and.

The general proclaimed the in 1941 but colonial rule continued until 1943. Baalbek still has its railway station but service has been discontinued since the 1970s, originally owing to the. Main article: The began with a July 12 ('Operation Truthful Promise') that killed 8. Another two— and —were believed to have been abducted alive but were later killed and then refrigerated.

By this time, Baalbek was a stronghold: aerial bombardment on July 17 destroyed a dairy processing plant, gas stations, and Hezbollah offices. Having been warned by the IDF prior to air strikes, the vast majority of the population subsequently fled in expectation of further attacks. On the evening of August 1, hundreds of soldiers raided Baalbek and the Dar al-Hikma or Hikmeh Hospital in Jamaliyeh to its north ('). They were transported by helicopter and supported by and, The was acting on information that Goldwasser and Regev were at the hospital while and other sources claimed the IDF was attempting to capture senior Hezbollah officials, particularly. The hospital had been empty for four days, the most unwell patients having been transferred and the rest sent home.

No Israelis were killed; Five civilians were abducted and interrogated by the Israelis, presumably because one shared his name with, the secretary general of Hezbollah; they were released on August 21. Another 9 civilians were killed on August 7 by a strike in the middle of, just south of Baalbek, and by the subsequent attack on the car leaving the scene for the hospital. On August 14, just before the ceasefire took effect, two Lebanese police and five Lebanese soldiers were killed by a drone strike while driving their van around the still-damaged road through Jamaliyeh. Conservation work at Lebanon's historic sites began in October. The ruins at Baalbek were not directly hit but the effects of blasts during the conflict toppled a block of stones at the Roman ruins and existing cracks in the temples of Jupiter and Bacchus were feared to have widened. Frederique Husseini, director-general of Lebanon's Department of Antiquities, requested $550,000 from Europeans to restore Baalbek's souk and another $900,000 for repairs to other damaged structures. See also:,,,,, and The Tell Baalbek temple complex, fortified as the town's citadel during the Middle Ages, was constructed from local stone, mostly white and a rough white.

Over the years, it has suffered from the region's numerous earthquakes, the iconoclasm of Christian and Muslim lords, and the reuse of the temples' stone for fortification and other construction. The nearby, a 13th-century on the old road to Damascus, is built out of granite columns, apparently removed from Baalbek. Further, the jointed columns were once banded together with iron; many were gouged open or toppled by the emirs of Damascus to get at the metal. As late as the 16th century, the Temple of Jupiter still held 27 standing columns out an original 58; there were only nine before the and six today. [ ] The complex is located on an immense [ ] raised plaza erected 5 m (16 ft) over an earlier T-shaped base consisting of a podium, staircase, and foundation walls. These walls were built from about 24, at their lowest level weighing approximately 300 tonnes (330 tons) each.

The tallest retaining wall, on the west, has a second course of monoliths containing the famous ' (: Τρίλιθον, ): a row of three stones, each over 19 m (62 ft) long, 4.3 m (14 ft) high, and 3.6 m (12 ft) broad, cut from. They weigh approximately 800 tonnes (880 tons) each. A fourth, still larger stone is called the: it lies unused in a nearby quarry 800 m (2,600 ft) from the town. Its weight, often exaggerated, is estimated at 1,000 tonnes (1,100 tons). A fifth, still larger stone weighing approximately 1,200 tonnes (1,300 tons) lies in the same quarry.

This quarry was slightly higher than the temple complex, so no lifting was required to move the stones. Through the foundation there run three enormous passages the size of railway tunnels. The temple complex was entered from the east through the ( προπύλαιον, propýlaion) or Portico, consisting of a broad staircase rising 20 feet (6.1 m) to an arcade of 12 columns flanked by 2 towers. Most of the columns have been toppled and the stairs were entirely dismantled for use in the nearby later wall, but a Latin inscription remains on several of their bases stating that Longinus, a lifeguard of the, and Septimius, a freedman, gilded their capitals with in gratitude for the safety of 's son and empress. Immediately behind the Propylaeum is a hexagonal forecourt reached through a threefold entrance that was added in the mid-3rd century by the emperor. [ ] Traces remain of the two series of columns which once encircled it, but its original function remains uncertain.

Reckoned it as the town's. Badly preserved coins of the era led some to believe this was a sacred grove, but better specimens show that the coins displayed a single stalk of grain instead. The rectangular Great Court to its west covers around 3 or 4 acres (1.2 or 1.6 ha) and included the main for, with -floored basins to its north and south, a, and three underground passageways 17 ft (5.2 m) wide by 30 ft (9.1 m) high, two of which run east and west and the third connecting them north and south, all bearing inscriptions suggesting their occupation by Roman soldiers.

These were surrounded by, one of which was never completed. The columns' bases and capitals were of limestone; the shafts were monoliths of highly polished red 7.08 m (23.2 ft) high. Six remain standing, out of an original 128. [ ] Inscriptions attest that the court was once adorned by portraits of 's daughter,,, and, dedicated by the city's Roman colonists. The was richly decorated but now mostly ruined. A westward-facing basilica was constructed over the altar during the reign of; it was later altered to make it eastward-facing like most.

The Great Court of ancient Heliopolis's temple complex The Temple of Jupiter—once wrongly credited to —lay at the western end of the Great Court, raised another 7 m (23 ft) on a 47.7 m × 87.75 m (156.5 ft × 287.9 ft) platform reached by a wide staircase. Under the, it was also known as the ' from the three massive stones in its foundation and, when taken together with the forecourt and Great Court, it is also known as the Great Temple. The Temple of Jupiter proper was circled by a of 54 unfluted: 10 in front and back and 19 along each side. The temple was ruined by earthquakes, destroyed and pillaged for stone under, and 8 columns were taken to () under for incorporation into the.

[ ] Three fell during the late 18th century. 6 columns, however, remain standing along its south side with their entablature. Their capitals remain nearly perfect on the south side, while the 's winter winds have worn the northern faces almost bare. The and blocks weigh up to 60 tonnes (66 tons) each, and one corner block over 100 tonnes (110 tons), all of them raised to a height of 19 m (62.34 ft) above the ground. Individual were not capable of lifting stones this heavy.

They may have simply been rolled into position along temporary earthen banks from the quarry or multiple cranes may have been used in combination. [ ] They may also have alternated sides a little at a time, filling in supports underneath each time. [ ] The enriched its sanctuary in turn. In the mid-1st century, built the tower-altar opposite the temple. In the early 2nd century, added the temple's forecourt, with of shipped from at the southern end of. [ ] The —once wrongly credited to Jupiter —may have been completed under in the 190s, as his coins are the first to show it beside the Temple of Jupiter.

[ ] It is the best preserved of the sanctuary's structures, as the other rubble from its ruins protected it. [ ] It is enriched by some of the most refined reliefs and sculpture to survive from. The temple is surrounded by forty-two columns—8 along each end and 15 along each side —nearly 20 m (66 ft) in height. [ ] These were probably erected in a rough state and then rounded, polished, and decorated in position. The entrance was preserved as late as and, but the of the had slid 2 ft (1 m) following the; a column of rough masonry was erected in the 1860s or '70s to support it. The also damaged the area around the 's famed inscription of an eagle, which was entirely covered by the keystone's supporting column.The area around the inscription of the eagle was greatly damaged by the. The interior of the temple is divided into a 98 ft (30 m) and a 36 ft (11 m) or sanctuary on a platform raised 5 ft (2 m) above it and fronted by 13 steps.

The screen between the two sections once held reliefs of,, and his dolphin, and other marine figures but these have been lost. The temple was used as a kind of for the medieval Arab and Turkish fortifications, although its eastern steps were lost sometime after 1688. Much of the portico was incorporated into a huge wall directly before its gate, but this was demolished in July 1870 by Barker [ ] on orders from 's governor. Two spiral staircases in columns on either side of the entrance lead to the roof.

The Temple of Venus—also known as the Circular Temple or Nymphasum —was added under in the early 3rd century [ ] but destroyed under, who raised a basilica in its place. Considered it the 'gem of Baalbek'.

It lies about 150 yd (140 m) from the southeast corner of the Temple of Bacchus. It was known in the 19th century as El Barbara or Barbarat el-Atikah (St Barbara's), having been used as a church into the 18th century. The ancient walls of Heliopolis had a circumference of a little less than 4 mi (6 km). Much of the extant fortifications around the complex date to the 13th century reconstruction undertaken by the sultan following the devastation of the earlier defenses by the army under.

This includes the great southeast tower. The earliest round of fortifications were two walls to the southwest of the Temples of Jupiter and Bacchus. The original southern gateway with two small towers was filled in and replaced by a new large tower flanked by curtains, [ ] probably under.

Bahram Shah replaced that era's southwest tower with one of his own in 1213 and built another in the northwest in 1224; the west tower was probably strengthened around the same time. An inscription dates the -like strengthening of the southern entrance to around 1240. Qalawun relocated the two western curtains [ ] nearer to the western tower, which was rebuilt with great blocks of stone.

The barbican was repaired and more turns added to its approach. From around 1300, no alterations were made to the fortifications apart from repairs such as Sultan 's restoration of the moat in preparation for Timur's arrival. Material from the ruins is incorporated into a ruined mosque north of downtown and probably also in the on the road to. In the 19th century, a 'shell-topped canopy' from the ruins was used nearby as a, propped up to show locals the direction of for their.

Tomb of Husayn's daughter [ ] Under a white dome further towards town is the tomb of Kholat, daughter of and granddaughter of Ali, who died in Baalbek while Husayn's family was being transported as prisoners to Damascus. Ecclesiastical History [ ] Heliopolis (in Phoenicia; not to be confused with the Egyptian bishopric ) was a bishopric under Roman and Byzantine rule, but it was wiped out by Islam.

In 1701, Eastern Catholics () established anew an, which in 1964 was promoted to the present. Titular see [ ] In the Latin rite, the Ancient diocese was only nominally restored (no later then 1876) as of Heliopolis (Latin) / Eliopoli (Curiate Italian), demoted in 1925 to Episcopal, promoted back in 1932, with its name changed (avoiding Egyptian confusion) in 1933 to (non-Metropolitan) Titular archbishopric of Heliopolis in Phoenicia.
