PRODUCT DESCRIPTION

TacFire RK300LPK: Build a powerful and reliable AR platform with the Tacfire .300 BLK 16" Rifle Kit, a complete unassembled kit designed for shooters looking to create their own .300 AAC Blackout rifle. At the core is a 16-inch .300 BLK barrel with a 1:8 twist and 5/8x24 threading, paired with a pistol-length gas system and .750 low-profile gas block for dependable cycling.

The kit includes a nitride-finished 5.56/.300 BLK bolt carrier group that is HPT/MPI tested, along with a forged upper receiver featuring M4 feed ramps for smooth and reliable feeding. A 15-inch slim M-LOK free-float handguard provides a lightweight platform for accessories while maintaining excellent handling.

Also included are a lower parts kit with trigger and hammer, mil-spec 6-position stock, mil-spec buffer tube, 3 oz buffer, buffer spring, standard receiver end plate, and castle nut. Finishing components such as the charging handle, dust cover, forward assist, and A2 flash hider complete the package, giving builders everything needed to assemble a capable .300 Blackout rifle.

NOTE: YOU WILL NEED A STRIPPED LOWER RECEIVER TO COMPLETE THIS
