Machined entirely in house, we manufacture these forged 7075 lowers to better than Mil-Spec. Each unit starts as a 7075 mil-spec forging. ZRTS machines the units to 80% completion meeting all ATF requirements for an 80% AR lower. Magwell corners are broached. Includes “Gen 2” pocket for upper receiver test fitting. ZRTS lowers include enhanced features such as a threaded bolt catch pin and rear take down pin detent set screw. These components are included with each lower. These are raw aluminum with a tumbled finish.
We manufacture these in house and will fill any backorders in 24 hours!
