One of the most versatile calibers in the world in rifle form!
You can make your 9mm ammo do more for you with this AR-9 side-charging rifle kit. This full-sized AR-15 length rifle has been chambered and built to share ammo from your 9mm sidearm, which means you can push it further and more accurate than you could with your pistol. Its left-side-charging functionality means you never have to take your firing hand off your grip. It also features a 15″ MLOK handguard, so you can attach the widest range of foregrips, tactical lights and lasers, or anything else that employs the MLOK mounting system.
All the internals, the BCG and lower parts kit, have been designed to function with any 9mm lower receiver as well, or even an 80% 9mm lower.
What’s Included
This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock.
