It provides a link from the M4, a major motorway linking London and South Wales, to Bristol city centre and is maintained by Highways England, the national roads body. The motorway was planned concurrently with the M4 in the 1960s, and construction was complete to Eastville in northeast Bristol by 1970. The southernmost section was delayed by engineering challenges and industrial action, and did not open until 1975. Since the mid-2000s, there have been plans to use the M32
M4 carbine tube at a straight angle, resulting in part wearing. This can also tilt the bolt during extraction, leading to increased bolt lug failures. The third is that the use of a sound suppressor results in hot gases entering the chamber, regardless of a direct-gas impingement or gas piston design choice. The gas piston system may also cause the firearm to become proprietary to the manufacturer, making modifications and changes with parts from other manufacturers difficult. The M4 was developed and produced for the United States government by Colt Firearms, which had an exclusive contract to produce the M4 family of
