TacFire AR Pistol Build Kit 45 ACP 7.5" - Black Nitride

The TacFire AR Pistol Build Kit is a component package for assembling an AR-pattern pistol in 45 ACP. It is a build kit, not a complete firearm, and includes a lower-parts kit along with the upper, operating, and buffer components needed for the listed configuration.

Its 7.5 in steel barrel wears a black nitride finish and has 5/8x24 muzzle threads. A birdcage flash hider and crush washer are included. The barrel is paired with an ultra-slim 7 in free-floating aluminum M-LOK handguard using a clamp-on mounting arrangement.

The kit includes a stripped billet-aluminum AR-15 upper receiver with M4 feed ramps, described as compatible with 5.56, .223, and .300 AAC components. Operating parts include a steel .45 ACP Glock-pattern bolt-carrier group and a mil-spec AR-15 aluminum charging handle with a steel latch.

For the rear of the build, the package supplies a pistol buffer tube with foam covering, 5.5 oz steel buffer, buffer spring, standard receiver end plate, and a steel mil-spec/commercial castle nut. A USA-made AR-15 lower-parts kit and black polymer A2-style pistol grip round out the listed components.
