For use with .22LR AR15 conversion kits ONLY. These barrels fit standard AR15/M4 uppers and come with either a .217"/.222" (subsonic) or .218"/.222" (standard 22LR) bore and groove rifling but with a .223Rem chamber to accept most types of AR15 to 22LR conversion kits, but without sacrificing accuracy/velocity from using the slightly larger bore/groove diameter of a center-fire .223.
AR22 specific contours now available!
Our 4-sizes (Ultralight, Light, Medium, Heavy) of AR22 Specific Contours have no GB journals at all and will have a far cleaner, more minimalistic contour than our standard gas-system based AR barrel contours.
-----Must be used with an AR-15 to 22LR Conversion Kit (.22LR Chamber Insert type for .223Rem) and fired ONLY with .22LR AMMO-----
