The rifle carries the Windham, Maine B.F.I. rollmark with Bushmaster snake logo and model/caliber markings: "B.F.I. WINDHAM, ME. U.S.A.," "MOD. XM15-E2S," and "CAL .223–5.56MM." The barrel is stamped "B MP 5.56 NATO 1/9 H BAR," indicating a chrome-moly heavy profile with 1:9 rifling twist.
Its A2 configuration includes a fixed carry handle with 8/3 elevation drum rear sight, a fixed A-frame front sight with square post, brass deflector, forward assist, and ejection port cover. The rifle uses a direct-impingement, semi-automatic action on the AR-15 platform.
The 20 inch HBAR is crowned and non-threaded, matching the post-ban era configuration (1994–2006). The heavy profile provides rigidity, and the 1:9 twist is suitable for common 5.56 NATO usage as marked.
Furniture is classic A2: a fixed polymer stock with trapdoor buttplate and sling loop, rifle-length two-piece ribbed polymer handguards, and an A2 pistol grip. The rifle has a manual safety, a 13.5 inch length of pull, and accepts STANAG/AR-15 pattern magazines. Stated capacity is 30+1 with standard magazines.
