NFM Gen 4 Carbine

Product Features:

Our 7075 billet uppers feature a medium weight design for increased strength, while our modular handguard gives a true free float to the rifle which improves harmonics of the bullet for increased accuracy. Our handguard has flute cuts for improved cooling and reduced weight. 2-piece heat sink and barrel nut act as a radiator to dissipate heat which allows the rifles continuous operation to run cool. The heat sink and barrel nut also have two stabilization points for a perfect center run of our piston operating rod.

The complete top rail allows for a true sight center so optics can be mounted and adjusted easily. Our SUB-MOA hand lapped HBAR match, fluted barrels are chambered in .223 Wylde with a 1/7 twist. Barrels are 416 stainless which have been cryogenically stabilized and nitrided for improved accuracy, life and velocity. Every NFM Gen 5 Carbine, like all our carbines, are hand fitted to ensure the tightest and best fit possible.

All piston rifles are equipped with our NFM SMAART Weapons System.
