Premium Lower Parts Kit with Premium Billet Fire/Safe Marked 80% Lower



The Premium 80% Lower Fire/Safe Marked Billet has been redesigned with some features that will make your life easier during build time or any time you need to disassemble it to swap out parts for upgrades or whatnot. Now, instead of a standard bolt catch roll pin hole you get a threaded bolt catch release hole as well as a threaded rear takedown detent hole. This alteration means it's easier to install/uninstall.  More importantly, it means no more hammering.  You no longer risk hitting the side of your lower and chipping the finish.
