9mm AR9 80 Lower
We partnered with some of the country's best gunsmithing experts to bring a new version of the 9mm AR-9 80% lower to market. These by-design, USA-made billet aluminum lower receivers are not like any old 9mm AR-15 "box conversion" kit (nobody wants a skinny magazine in a big 5.56 mag well, anyway).
Mil-Spec, Compatible with AR-15 LPKs and Parts
Engineers took the time to develop these proprietary 80% lowers to work with the standard AR-15 lower parts kit, buffer tubes, and buttstocks, all current AR-15 80% jigs, all factory and aftermarket Glock® magazines, the popular G-9 Hybrid 9mm bolt carrier group, and current AR9 uppers on the market! If you want to build the baddest 9mm AR pistol from scratch and proudly call it your own creation, this new lower is the ticket. It provides black rifle compatibility and customization potential without breaking the bank.
We cover parts compatibility in detail, 9mm ballistics in a carbine setup (chart included), what barrel length and twist rate are best, and what type of buffer is required to accommodate your AR9's blow-back gas operation.
