AR9 Pistol Kit (10.5" Barrel & 9" M-LOK Handguard) with 9MM 80% Lower



AR9 Pistol Kit (10.5" Barrel & 9" M-LOK Handguard) with 9MM 80% Lower The AR market is just now beginning to showcase some pretty cool departures from the usual .223 and 5.56 “stuff”. Notably, that includes pistol-caliber carbines. Unfortunately, all this new stuff has been expensive – until now! 80-Lower is proud to announce the first-ever, 9mm AR 15 Complete Built Kit, including a billet 80% lower, built by design, specifically for 9mm!

This new kit is completely exclusive to 80-Lower, thanks to our partnership with some industry leaders. This is the first billet 7075 true 9MM lower receiver currently available on the market. Featuring a hard coat anodized finish, engraved with Fire and Safe markings, ambidextrous mag release, enlarged mag feed ramps for competition shooters, compatible with Glock magazines, and finally, this 80% lower is compatible with existing jigs, too!

The upper in this kit comes prebuilt, head-spaced, and ready to fire out of the box. You’ll enjoy superior accuracy thanks to a Chromoly 10.5” barrel featuring a nominal 1:10 twist and nitride, heat-treated finish. A billet 7075 T6 upper receiver houses a 9mm G-9 Hybrid BCG, built from 8620 steel. This hybrid bolt includes a charging handle, ready to go out of the box.

The included lower parts kit ensures a crisp, smooth trigger affords little creep, take-up, or over-travel. The provided SOB brace, 9” M-Lok free-floating railed handguard, and Magpul grip provides increased accuracy and comfort and helps keep your new 9mm AR pistol compact, lightweight, and maneuverable.
