Built on forged 7075-T6 aluminum receivers, this XM15-E2S features the Windham, ME B.F.I. rollmark and an L-prefix serial below L063000, indicating pre-ban assembly on or before September 13, 1994. This places the rifle in the desirable early Bushmaster production period.
The rifle wears a Colt-marked "C MP 5.56 NATO 1/7 HBAR" 20-inch barrel with a chrome-lined bore and chamber. It uses a rifle-length gas system and a threaded muzzle. The A-frame front sight base includes a bayonet lug and a front sling swivel.
Its A2 fixed carry-handle upper includes a brass deflector and A2 iron sights with windage and elevation adjustments at the rear and an A2 front post. The platform is direct impingement, semi-automatic, chambered in 5.56mm NATO, with a capacity of 20+1.
Furniture is true to the period: vented rifle-length polymer handguards with circular vent holes, a fixed stock with trap-door storage, a checkered metal buttplate, and a rear sling loop. A textured polymer grip complements the setup, and the length of pull measures 13.75 inches.
Additional details include the AR-15 HBAR profile barrel, 1:7 twist rate, and U.S. manufacture. The combination of the Windham rollmark, pre-ban status, and Colt-marked HBAR barrel makes this example noteworthy for those seeking a correct A2-era configuration.
