OPTIONAL UPGRADE: DiamondHead D45 Swing Sites

The revolutionary Diamondhead® D-45 Integrated Sighting System takes sighting to a new level. If a fast, accurate CQC target acquisition is needed or the optic goes down, simply flip out the D-45 sights and roll the weapon 45 degrees counter-clockwise. The D-45 REAR sight’s patented diamond-shaped aperture and diamond-shaped upper housing allow the eye to place the D-45 FRONT sight’s post in the exact center of the rear sight’s aperture. The spring-loaded D-45 deploys fast and stows flat with a push of a button.

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. Our 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.

The revolutionary DiamondHead D45 sights store flat on the top picatinny and flip out 45 degrees to the 1 O’clock position for fast and accurate CQC target acquisition.

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