TacFire SS-RK300LPK AR Build Kit 300 Blackout 16" Black Nitride

The TacFire SS-RK300LPK AR Build Kit is an unassembled Rifle-series component set for a custom AR-platform configuration in .300 AAC Blackout. It is configured around a 16 in black-nitride barrel, semi-auto operating configuration, and a black aluminum component package.

The kit uses a pistol-length steel gas tube with pin and a .750 in Mil-Spec steel low-profile gas block. An ultra-slim, clamp-on free-floating M-LOK handguard provides M-LOK accessory slots, while the supplied stripped billet AR-15 upper receiver has M4 feed ramps and is compatible with 5.56, .223, and .300 AAC Blackout configurations.

Additional components include a Mil-Spec aluminum charging handle with steel latch, dust cover, forward assist, .308-caliber spiral-fluted flash can with crush washer, and an AR-15 pistol buffer tube with foam covering, 3 oz buffer, and buffer spring. The lower-build components include a USA-made AR-15 lower-parts kit, standard receiver end plate, steel Mil-Spec/commercial castle nut, and black A2-style pistol grip.

This kit is offered in New Condition.
