The ATI Milsport is American Tactical's accessible AR-15 line, and this version is chambered in .300 Blackout, a cartridge built to run both supersonic and subsonic loads. A 16.00" barrel keeps it a full rifle and keeps it out of NFA territory.
The rifle feeds from 30-round magazines that share the standard AR-15 footprint, so .300 Blackout loads up just like 5.56 in the same magazine wells and pouches. It is a straightforward way to add the Blackout cartridge to the safe for range work and hunting.
