Don't regret the purchase.
Was a little worried about the accucam getting snagged (opened) on brush or the mouth of an Eberlestock. Had no problems with the accucam staying closed, though originally planned on zip-tying the front of the lever to the front/cantilevered ring-base. Worries here were all imagined apparently.
Haven't done repeatability tests to see how much the mount is (or if it is) off when taken on and off of the rail. After a 300yd zero did take it off, put it back on, and was banging small torso plates at 300 and 400 with no correction (1-6 optic), but this is just banging steel, not as detailed feed-back as paper would give at 300 or 400.
Overall, happy but haven't tried the Larue, ARMS, Bobro, or other alternatives...
