The A2 configuration defines this rifle: a fixed carry-handle upper with forward assist, case deflector, and ejection port cover, paired with an A2 rear aperture sight adjustable for windage and elevation. Up front, the forged A2 front sight base includes a bayonet lug and sling swivel for classic utility.
The 16-inch barrel is marked "B MP 5.56 NATO 1/9," reflecting Bushmaster proofing and a 1:9 twist suited to a wide range of 5.56mm loads. It uses a carbine-length gas system and is capped with an A2 birdcage flash suppressor, with standard delta ring retention and double heat-shield carbine handguards.
The rifle runs a direct-impingement action on aluminum receivers and includes a selector safety and a standard charging handle. It accepts STANAG magazines and is configured for a 30+1 capacity.
Furniture is classic M4-style: a Bushmaster-logo 6-position collapsible stock with a 14.25-inch length of pull, an A2 polymer pistol grip, and ribbed polymer handguards with dual heat shields. Materials and markings include polymer furniture, aluminum receivers, and B.F.I. WINDHAM, ME U.S.A. rollmarks.
Produced during the 2006–2011 era in Windham, Maine, this XM15-E2S A2 combines period-correct features with clean execution and complete accessories, ready for range use or collection.
