Machined entirely in house, ZRTS manufactures 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 fits. ZRTS lowers include enhanced features such as a threaded bolt catch pin and rear takedown pin detent set screw. These components are included with each lower. Lowers are Mil-Spec black anodized.
Don’t compare their lowers to basement bandit pricing. You are receiving, tight fitting, premium machined lowers. We machine each lower for a tight upper receiver fit to minimize rattle. The same goes for their trigger guards. We test each unit for fitment with Lancer, Pmag, and US GI magazines to ensure drop-free mag changes. Our threaded bolt catch pin allows the builder to quickly install their catch without a punch so you don’r mar the finish!
NOTE: We will NOT ship to NJ. All orders placed will be cancelled and assessed a cancellation fee. This is due to NJ state suing 80% dealers
