BM-9/AR-9 Upper Build Kit Specifications
The Brigade BM9 8.5 AR9 Pistol Build Kit is engineered for builders who want full control over their firearm setup while maintaining premium performance. The most Versatile 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 build kit 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.
