The New BM-9 9mm Battle Pistol by Brigade Manufacturing is one of the nicest and most advanced AR platform pistols 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.
