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 our 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 our 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 NY & NJ. All orders placed will be cancelled and assessed a cancellation fee.  This is due to NJ & NY state suing 80% dealers


NOTE: These are produced in house and we machine more every day.  When out of stock, the longest lead time comes from anodizing which is maximum one week.  We fulfill all orders first in, first out.  Raw lowers have a 48 hour max out of stock lead time.

    Don’t like the micro screw in bolt release. Had to drill it out and use a roll pin

    The threaded bolt catch and threaded rear takedown detent hole are awesome! However the finish on this lower is very poor, it’s rough and there are imperfections in the surface. By far the roughest finish on a lower I’ve ever seen.
