Build one of the most accurate 9mm weapons ever.
Acquiring a tack-driving 9mm rifle couldn't be easier, thanks to this AR9 side-charging build kit. Featuring a heavy-profile 4150 CMV barrel housed in a lightweight M-LOK handguard and custom billet receiver, this upper is ready to drive 9mm rounds to 200 meters and beyond.
Down below, you're getting a quality mil-spec lower parts kit, 9mm-compatible buffer assembly, and a classic M4-type adjustable stock.
Pair this build kit with any AR9 lower receiver -- a retail or 80% 9mm lower works all the same -- and you'll be ready to hit the range.
