I put one on my A1(ish) build. Took the scope to a local gun shop before I mounted it and found scope caps to fit it. Once I mounted it, I played around with it for a while. When I went to put it away, I went to close the caps.
Pushing on the rear cap, the scope slid forward. Pushing on the front cap, it slid backward. OK, that can't be good. Took it back off. Looking at the mounting lever assembly, I figured out the top of the threaded tube was bottoming out on the bottom of the mount before it could pull be pulled down tight enough.
The lever assembly is held together by an E clip set into a groove on the threaded tube. I pushed that off and disassembled it. Used a file to shorten the threaded tube, checking how it was affecting fit frequently (the E clip is only used to hold the assembly together for convenience, I did not put it back on while checking fit).
Originally, the lever bottomed out with the lever in the forward position. I ended up taking off enough to let the lever make an additional 1.5 turns and lock in the rear position before It was tight enough that the scope wouldn't slide when applying pressure to the front or rear.
When I was finished, there was barely enough material left on the top of the threaded tube to retain the E clip. Had I removed more, I would have had to leave the E clip off (as stated above, its only function is to keep the mounting lever assembly together for convenience). I might have been able to cut another groove for it slightly lower on the tube.
You may or may not have this issue, just depending on the dimensions of your carry handle, which may depend on who made the forging, who machined the forging, etc.(mine is anAnchor Harvey marked C7 from Fulton Armory) but its a pretty easy fix if you do.
