The BRF-15 9mm Rifle by Brigade Manufacturing is one of the nicest and most advanced AR platform rifles that we have seen to date. We predict that it is going to take the marketplace by storm. Each BM-9 features a forged Mil-Spec 7075-T6 aluminum upper and lower receiver making the firearm not only immensely strong but also compatible with most standard AR-15 accessories. This means that standard AR-15 charging handles and trigger sets will fit. They feature a 1 in 10 twist button pulled Black Nitride coated barrel for maximized accuracy and long life. The highly advanced free-floating lightweight U-Loc rail design is relatively new to the marketplace and not only does it look great but it is compatible with and will accept all standard keymod and M-Loc attachments. The upper and free float rail both feature a 1913 Picatinny rail for sights or optic attachments and the rail has been laser aligned to the upper to assure proper alignment. The BRF-15 compliant rifle is compatible with all 9mm Glock style magazines. The BRF-15 models feature a beautiful professionally applied cerakote finish that provides both a highly durable and uniquely beautiful finish.
