Product Description

Adams Arms AR-15 C.O.R. Ultra Lite A3 Gas Piston Upper Receiver Assembly 5.56x45mm NATO 16.5″ Barrel No Sights

Designed with competition shooters, the new C.O.R. Upper is the optimal setup for competitive shooting and is ready to go right out of the box! (just add an optic)

This upper was designed with a comprehensive approach to create the lowest felt recoil pulse while maintaining ultimate accuracy and maneuverability.

The VDI Ultra-Lite Barrel runs extremely light and accurate. The New Low Mass Carrier and Rifle Length System significantly reduces felt recoil, and the VDI Jet Comp virtually eliminates muzzle rise for follow up shots.

All Adams Arms products are made in the USA and come with a Life-Time Warranty.
