BM-9 Specifications

The BM-9 Complete upper with a 9.5 inch barrel is 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.
