Convert your standard AR-15 into the ultimate high-volume training and plinking tool with the Chiappa Firearms M4-22 Complete Upper Receiver Assembly (MPN: 500095).

The Chiappa M4-22 features a 16-inch heavy contour steel barrel with a 1:16" twist rate, precisely optimized for stabilizing standard and high-velocity .22 Long Rifle rounds. The barrel is finished in a durable black parkerized coating and encased in a lightweight, rigid 11.80" quad picatinny rail handguard—giving you full-length estate to mount your favorite red dots, magnifying optics, tactical lights, and vertical grips.
Constructed with a durable A3 polymer upper receiver housing, this complete rimfire conversion kit is a true drop-in solution.
