That’s about 50% more kinetic energy than a standard .223/5.56mm 55-grain bullet moving at 3,000 feet per second.
The split receiver design of AR-type rifles lends itself to using a standard lower receiver with stock, grip, magazine well, and fire control system containing trigger, hammer, sear and safety mechanisms.

As an AR-type rifle cartridge, I love that it fits in standard .223 / 5.56mm magazines.

Bill Alexander and Janne Pohjoispää developed this round as a way to make a standard AR rifle reach out to 800 (and more) yards.
