Stag Arms is now offering its AR-15 carbine rifles in the popular 300 AAC BLK / 7.62x35 mm cal. Models the offer currently applies to are  the 1, 2, 2T, 3, 3T, and 3T-M series of rifles, and will cost buyers an additional $50.

"In addition to the upper halves we offer in this caliber we are now offering a complete AR-15 rifle using the 300 Blackout cartridges with heavier bullets, great ballistics, and already on the shelves of most major stores.” Said Stag Arms president Mark Malkowski. “By utilizing the same reliable AR-15 firearm platform customers can still use their standard accessories."

Barrels are manufactured from 4140 steel with chrome lining on the inside to increase durability. Its 1:7” twist rate is designed to work with all bullet weights in the caliber; and barrel thread for the muzzle device is 5/8x24.

The supersonic 300 AAC Blackout cartridge was designed to closely match the ballistics of 7.62x39 mm 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 7.62x39 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.
