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).
Engineers took the time to develop these 9mm 80% lowers to work with the standard AR-15 lower parts kit. This lower also works with mil-spec buffer tubes and buttstocks, and factory and aftermarket Glock® magazines and parts, including the popular G-9 Hybrid 9mm bolt carrier group. This lower also works with current AR9 uppers available on the market!
If you want to build an accurate 9mm AR pistol 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. Grab a 9mm AR9 build kit to complete assemble your finished lower.
