Having a dedicated training upper receiver like CMMG Upper Complete Sierra .22 LR 16 Inch SS Action just makes sense and when it saves you ammunition costs, it makes dollars and cents. The Mil-Spec M-4 upper receiver has a ceramic finish and a Stainless Steel .22 Long Rifle caliber action for many years of trouble free and cost effective shooting. Made of carbon steel the 16 inch W.A.S.P., barrel has a 1 in 16 inch twist, a Mil-Spec 1/2 X 28 threaded muzzle and an A1 flash hinder. W.A.S.P. is a finishing process that is more abrasion and corrosion resistance than hard chrome or phosphate finishes giving you years of shooting fun.

The live round extraction feature helps with functioning drills and the anti-jam changing handle keeps stoppages to a minimum.
