The TacFire BU45ACP7 Pistol Upper Assembly brings .45 ACP performance to the AR platform in a compact, ready-to-run package. Built around a 7" black nitride barrel and a black anodized 7075-T6 aluminum receiver, it pairs a free-float M-LOK handguard with a complete bolt carrier group so you can drop it onto a compatible lower and head straight to the range.

This upper is optic ready, letting you choose your preferred sighting system, and the included A2-style flash hider helps control muzzle flash from the short barrel. With its M-LOK handguard, it offers ample mounting space for lights or accessories, making it well suited for range use, training, or building a compact AR-pattern pistol. TacFire’s attention to materials and machining gives this assembly dependable function and long-term durability.
