What's Included
- Bushmaster XM15-E2S A3 Flat-Top rifle

The A3 flat-top receiver with detachable carry handle provides a versatile sighting setup, while the receiver itself bears Windham, ME B.F.I. markings. It includes a forward assist, brass deflector, and ejection port cover, consistent with a well-equipped AR-15 pattern carbine.
The 16 inch barrel is marked "B MP 5.56 NATO 1/9," denoting magnetic-particle inspection and a 1:9 twist to stabilize common 5.56/.223 bullet weights. It is threaded and fitted with an A2 flash suppressor. The carbine-length gas system and polymer carbine handguards complete the proven carbine configuration.
Custom furniture adds practical enhancements: an ACE Ltd. USA fixed skeleton stock with foam cheek sleeve (13.5 inch length of pull) and a Hogue overmolded pistol grip for a secure, comfortable hold. The stock assembly is aluminum, keeping weight in check while maintaining rigidity.
Sights are classic iron units: an A2 front sight base with bayonet lug and front sling swivel, paired with a detachable A2-pattern rear sight integrated into the carry handle. The rifle accepts standard AR-15/STANAG magazines and includes a 30-round Magpul PMAG Gen M3. Markings include B MP on the barrel and B.F.I. receiver stamping.
