Adams Arms is a premier manufacturer of short stroke piston driven AR15 rifles. The C.O.R series of rifles are designed with the competition shooter in mind providing you an optimal set up right out of the box. This particular build features a rifle length piston with a 16.5" Ultra Lite contour VDI 4150 CM melonited barrel with a 1:7" twist. Threaded on the end is the VDI Jet comp which virtually eliminates muzzle rise for fast follow up shots. The rifle length system allows for the lowest recoil pulse while maintaining ultimate accuracy and maneuverability. The C.O.R. features a free floated Samson light weight modular handguard, a Magpul fixed stock, and the gorgeous Kryptek Typhon camouflage pattern.

Sights not included.
