BM-9/Ar-9 Build kit Specifications

The Brigade BM9 9.5 AR9 Pistol Build Kit is engineered for builders who want full control over their firearm setup while maintaining premium performance. The largest barrel length among our compact AR9 PCC models, offering better control over the firearm. With an 8-inch handguard, this size maximizes control and customization options for hand placement and accessories. 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. Customers favor this model for customization and control, as it supports grips and attachments while maintaining a compact design. It is ideal for range shooting, CQB, urban settings, and various tactical short-range applications.
