If you happen to be one of the few people who managed to acquire an Aimpoint CS, and you also wish it was a little higher up, cantilevered, or perhaps QD capable, here's what you've been looking for. This spacer allows you to hard mount an Aimpoint CS to any ACOG base (...or even to an A1 carry handle, if you're truly about that life).
7075 Aluminum, type 3 hard coat anodized
3x 10-32 screws included for standard ACOG bases
Installation Notes: The threaded posts are swaged from the factory to retain the nuts/1913 clamps. Gunsmith installation is recommended to ensure that the threads aren't damaged on the nuts/posts. To install just remove the 1913 clamps, slide the spacer onto the recoil lug, then replace the nuts.
