When in a crouching, sitting or prone position the shooter tends to “creep” up on the scope. In order to provide the shooter with the ability to gain more eye relief when in these positions, GG&G has introduced the new AC-30 Accucam QD Mounting Base with Integral 30mm Rings. This new mounting base is tall enough to provide clearance for the latest large objective lens–long range optics. The integrated Accucam Quick Detach Lever System provides the shooter with the ability to quickly remove the scope in order to utilize other optics as the mission may require, and have the confidence of 1/2 MOA repeatability upon reinstallation.The overall length of the AC-30 Accucam QD Mounting Base is five inches. The mounting base portion is four inches in length and with it’s skeletonized construction weighs only six ounces. The inside ring to inside ring dimension is 3 3/4 inches.Designed and manufactured to meet the rigors of combat and professional use, the AC-30 QD Mounting Base is manufactured from solid billet 6061 T6 aluminum alloy and has a Type III hard coat anodized matte black mil-spec finish. All edges have been dehorned to protect the operator. The base can be quickly installed on a dovetail rail in seconds by rotating the Accucam Cam Lever to the locked position. It can then be quickly removed by rotating the Accucam Cam Lever to the unlocked position. Unlike many QD systems, it is fully adjustable to fit Weaver and MIL-STD-1913 dovetails.The patent pending design allows you to adjust the tension to accommodate out of spec or worn dovetails. In tests, the Accucam Locking Lever System has shown to be repeatable to 1/2 MOA. The unique finger loop lever is easily operated, even with a gloved hand and the rounded design is ergonomic and virtually snag proof. The Accucam mechanism is manufactured from solid billet 4140 steel and manganese phosphated matte black per mil-spec.
