Description

This product is 100% Made in the USA! Our gas tubes, gas blocks and even roll pins are all proudly manufactured in the US. All Complete uppers are headspaced prior to shipping and test fired.

The BKF AR15 M4 MOD-1 Rail M-LOK series provides an alternative aesthetically progressive design that is lightweight with our 7075-T6 Steel barrel nut and attach method. The innovative attachment of the rail and the barrel nut provides a solid lockup, a seamless, strong joint that requires no timed alignment to the barrel nut itself. All BKF M4 MOD-1 rails (and receivers for that matter) are designed with pocketed cutouts to further minimize weight. In addition, BKF M4 MOD-1 rails offer QD mounting at the rear 3,6 and 9 O’clock of the handguard.

Faxon Match Series- 18″ Gunner, 6.5 Grendel, 416R, 5R, Nitride, Nickel Teflon Extension Features:

Faxon’s MATCH SERIES of barrels takes our renowned performance and value up a notch.

Manufactured 100% in-house from gun-barrel-quality bar-stock, the Match Series starts with 416-R in 5R rifling. 5R is a hybrid rifling, with lands opposite grooves and reduced sharp angles that reduces jacket deformation increasing velocity and easy cleaning. After rigorous testing, the barrels are Nitride treated inside and out, locking in the bore, improving barrel life, and keeping the elements at bay.

The extension is coated in Nickel Teflon which maintains incredible dry lubricity, corrosion resistance, and with the coating, tightens up fit between the extension and receiver – again improving upon accuracy. Combined, the Match Series of barrels are ready for when duty calls or the buzzer beeps with unrivaled performance value.
