When it comes to AR-15's Colt set the standard. This is the brand that the US Military has relied on for over 40 years. The Colt M4A1 SOCOM Carbine was designed specifically for lightweight mobility, speed of target acquisition, and potent firepower. The LE6920 employs a 6-groove, chrome-lined, 16-inch heavy profile barrel with a 1 in 7 twist that provides its users with both accuracy and dependability. With the 4-position buttstock fully retracted, the Colt Law Enforcement Carbine is less than 30.5 in (77.5 cm) in length and weighs only 7 lbs, making it ideal for tactical deployment and traditional patrol. Other features include a Knights Armament Quadrail handguard, a Maytech folding rear sight, a side sling swivel at the gas block, an M4 feed ramp, an H2 buffer, and an ambidextrous safety. M16-typle bolt carrier. 30 + 1 capacity.
