Stag Arms AR-15 Rifle 300 Blackout

Stag Arms has already offered 300 Blackout upper halves, but now the company has decided to release the entire package.

Stag has released its 16-inch AR-15 carbine rifles in the popular 300 AAC BLK / 7.62x35mm caliber. The company had researched and tested many different cartridges on the AR-15 platform before making a final decision.

The Model 1, 2, 2T, 3, 3T, & 3T-M series of rifles can now be purchased in the 300 Blackout caliber for an additional $50.

The barrels are 16 inches long and manufactured from 4140 steel with chrome lining on the inside to increase durability. The 1/7 twist rate is designed to work with all bullet weights in the caliber and the barrel thread for the muzzle device is 5/8×24.

The supersonic 300 AAC Blackout cartridge was designed to closely match the ballistics of 7.62×39 ammunition with a minimal number of non-interchange parts compared to a 5.56 NATO AR-15. To decrease the feeding issues that occurred with 7.62×39 ammunition on the AR-15 platform, the cartridge case was derived from the U.S. Military 5.56 NATO case and will work with standard AR-15 magazines while retaining their original ammunition capacity.
