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 Battle Receiver" is an M4A1 with a 10.3-inch barrel upper receiver. Current contractors for the Mark 18 are Colt and Lewis Machine & Tool (LMT) NSN 1005-01-527-2288. For the Individual Carbine competition, Colt submitted their "Enhanced M4" design, also known as the Colt Advanced Piston Carbine (APC). The weapon has a suppression-ready fluted barrel, which is lighter and cools better than previous M4 barrels. It is claimed to have "markedly better" accuracy. To improve reliability, Colt used an articulating link piston (ALP), which "reduces the inherent stress in the piston stroke by allowing for deflection and thermal expansion". In traditional
