The Close Quarter Battle Receiver (CQBR) [5] is a replacement upper receiver for the M4A1 carbine developed by the US Navy.. The CQBR features a 10.3 in (262 mm) length barrel (similar to the Colt Commando short-barreled M16 variants of the past) which makes the weapon significantly more compact, thus making it easier to use in, and around, vehicles and in tight, confined spaces.
The Block II program then focused on component improvements to the M4A1, with the adoption of the heavier "SOCOM profile" barrel in 2004 and free-float Rail Interface System II (RIS-II) handguard from Daniel Defense in 2008. Owing to the modularity of the AR-15/M4 platform, some operators have replaced issued optics, handguards, and buttstocks ...
The .458 SOCOM (11.63×40mmRB) is a moderately large round designed to work in an AR-15 platform.This is achieved by installing a 458 bolt and barrel. The 300-grain (19 g) round offers a supersonic muzzle velocity of 1,900 ft/s (580 m/s) and 2,405 ft⋅lbf (3,261 J), [1] similar to a light .45-70 but with a much smaller case.
The SOCOM 16 and SOCOM II are largely identical to the standard M1A, but feature a 16.25-inch (413 mm) barrel, rather than the standard model's 22-inch (560 mm) barrel. The specially designed muzzle brake is designed to reduce the increased recoil produced by the shorter barrel.
Daniel Defense also manufactures the 14.5 in (368 mm) barrel and gas block for USSOCOM's Upper Receiver Group-Improved (URG-I). [7] According to Forbes magazine, in 2016 Daniel Defense had sales of $73 million [1] [4] and 279 employees. [1] Marty Daniel stated in 2016 that 90% of the company's sales were to consumers, and 10% were to ...
An 18-inch (457 mm) (MOD 0/1) or 16-inch (406 mm) (MOD H) threaded-muzzle match-grade free floating stainless steel heavy barrel with a 1:7 (178 mm) rifling twist ratio is standard for the SPR. [11] [3] [13] The barrels are manufactured by Douglas Barrels with a unique contour that reduced weight but maintained rigidity for accuracy. [14]
