Colt 6920

The Colt LE6920, largely a civilian cousin of the M4 Carbine, though with a slightly longer barrel and a Magpul MBUS replacing the standard carry handle / sight.

The Colt 6920 (as well as the LE6920 and SP6920) series is a line of semi-automatic AR-15 rifles chambered in 5.56x45mm NATO made by Colt's Manufacturing Company. They are one of many model numbers and variations produced by Colt over the years and there are several variants that primarily differ in markings (e.g. "Law Enforcement Only" on the Colt LE6920) as per the 1994 Assault Weapons Ban. One exception is the Colt Model LE6920HB which along with law enforcement markings, also features a heavy barrel.
