Rainier Arms has just introduced their newest forged lower receiver compatible with both 45 degree and 90 degree safety selectors. Their lowers are made to mil-spec and machined from forged 7075 aluminum. Also features a tension screw, to help reduce any play between the lower and upper receivers, and a flared magwell to aid in quicker reloads.
