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.
It is constructed with modularity for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. [6] This family of rifles consists of two main types. The SCAR-L, for "light", is chambered in 5.56×45mm NATO and the SCAR-H, for "heavy", is chambered in 7.62×51mm NATO.
The Robinson Armament Co. XCR is a multi-caliber, gas piston weapon system developed by Robinson Armament Co. for U.S. Special Operations Command (SOCOM) to fill the requirements of the SOF Combat Assault Rifle, [5] or SCAR competition, but was disqualified on a technicality due to late delivery of blank firing adapters.
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]
A subvariant of the M4A1 uses a heavier barrel than the standard M4, as the regular M4 barrel, which can fire 6,000 rounds before requiring inspection for possible replacement, [20] was not sufficient for the higher consumption of ammunition by SOCOM operators. [38] The redesigned barrel, colloquially referred to as the "SOCOM barrel", has an ...
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.
The M110A2 is shorter than the original M110 and lighter as well at 10.5 lb (4.8 kg), which is comparable to the M110A1 SDMR's weight of 10.9 lb (4.9 kg) with no attachments save an unloaded magazine. The decreased overall length does not come at the cost of barrel length as the M110A2 still has a 20 in (510 mm) barrel. [2]
A major MRAD feature (and requirement of the military PSR solicitation) is a field-changeable barrel/caliber capability. Loosening two Torx screws in the receiver allows the removal of the barrel from the front of the receiver/handguard. With only a bolt face change, and in some cases a magazine change, caliber may be changed.
