The new Accucam Quick Detach Aimpoint Cantilever Ring has the same robust features as our original Aimpoint Cantilever Ring; the body is manufactured from solid billet 6061 T6 aluminum, six cap screws firmly hold the Aimpoint in place, and the insulated waterproof spare battery compartment with spare battery cap keeps the spare battery handy. The Accucam QD Locking Lever System provides you with a solid method to quickly install or remove your Aimpoint from the weapon system. The Aimpoint can quickly be 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. It is fully adjustable to fit Weaver and MIL-STD-1913 dovetails. The unique 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 design 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 black to mil-spec. GG&G Aimpoint Accessories, cantilever mounts, and rings are made in the USA at our Tucson Arizona factory. Scope mounts and mounting rings for tactical environments have to be made of top-grade material and machined to the finest tolerances, so they can perform in combat and police situations. Our components for Aimpoint, like the QD Cantilever Ring, are designed to enhance the trusted capabilities of Aimpoint's scope while giving more options to the AR-15 and M-16 operator.
