Faxon Firearms ARAK-21 5.56 NATO 16" 1:8 Twist Complete Upper - Muzzle Brake

The Faxon Firearms ARAK-21 complete upper brings Faxon's modernized AR-platform design to your existing mil-spec AR-15 lower. Chambered in 5.56 NATO (and compatible with .223 Remington), this upper is assembled around a 16" barrel with a versatile 1:8 rifling twist suitable for a wide range of bullet weights.

Finished in black and shipping with a muzzle brake pre-installed, the ARAK-21 uses the standard 1/2x28 muzzle thread pattern shared across the 5.56 AR platform, making it compatible with the wide ecosystem of 5.56 flash hiders, compensators, and sound suppressors on the market today. Pair this complete upper with any mil-spec AR-15 lower receiver to field a complete rifle without the cost or wait of a full factory build.
