BM-9 Specifications

The Brigade Manufacturing BM-9 Complete Upper features a 6.5-inch barrel and 5-inch U-Lok handguard, charging handle and BCG. The most compact AR9 PCC (Pistol Caliber Carbine) upper in the BM-9 series. The ramped barrel is designed to feed most modern defense ammunition which resolves a problem most AR9’s in the industry face. Built on a direct-blowback design, it delivers reliable performance, accurate pistol-caliber ballistics, and smooth handling in a streamlined profile.

This complete upper is compatible with many AR9 direct-blowback lowers (verify fitment before use) and accepts both M-LOK and KeyMod accessories through the U-Lok system. Compact enough to fit in a backpack or small range bag, the BM-9 upper is ideal for PCC builds focused on close-quarters battle (CQB), home defense, and urban tactical applications.
