AR-15 300 AAC (.300 BLACKOUT) Rifle Kits

The 300 AAC Blackout round was designed for effective close-quarters combat from the United States Military and has proven to be a very lethal and effective round when it comes to suppression as well. Our 300 AAC AR build kits come with full M-LOK rails, barrels, gas blocks, charging handles, forward assist, and other critical parts needed to complete the upper assembly. 
The 300 AAC round is a heavy hitter when it comes to size as it is much larger than a typical AR-15 .223/5.56 NATO round and falls into the .30 caliber category of rounds just like the AK47 7.62x39 round! This rifle kit build package also comes with collapsible and adjustable stocks with the buffer tube, weight, and springs including the castle nut with a pistol grip.
