Bushmaster XM-15-E2S AR Pistol in .300 AAC Blackout with BCM 9" Upper & Free-Float M-LOK Handguard
This XM-15-E2S pairs a pre-2011 Windham-marked Bushmaster lower with a BCM 9" .300 AAC Blackout upper, creating a compact, reliable AR-15 platform that leverages the caliber’s suppressed-ready performance.

The BCM MCMR-8 free-float handguard is machined from 6061-T6 aluminum and features M-LOK slots along the 3, 6, and 9 o’clock positions, giving you ample real estate for lights, grips, or other accessories while maintaining a slim profile.
The lower receiver is a forged 7075-T6 Bushmaster unit marked Windham, ME—sought after by some enthusiasts for its pre-2011 production pedigree. It retains the standard Mil-Spec controls and an A2-style polymer pistol grip for familiar handling.
A polymer stabilizing brace with a Velcro arm-strap delivers added support when shooting one-handed and keeps the overall length compact. The hard-coat anodized finish across both receivers presents a uniform, matte black appearance.
No sights are installed, allowing you to add the optic or iron sights of your choice via the continuous Picatinny rail on the upper receiver.
