[QUOTE="Tesoro, post: 1429632, member: 44340"] Well my first lapping experiment didnt go too well. The Talleys I ordered showed up with the wrong screws so I couldnt check them. I had my wheeler kit unpacked and I wanted to try it out. I found a pair of $200 Larue QD for my AR that werent used. So I put them on and checked alignment. They were off unless I took the mounts off and on to readjust a few times. I got them straight and then lapped. I found one high spot about 3x3mm and smoothed it out. I then washed them with dish soap and the black finish on the outside of the rings just melted right off!!! They are steel rings so ruined. I called Larue and was told tough **** because we say we dont recommend lapping and what you did using some compound obviously damaged the anodzing. Not true and not true! I sent an email to the head man see what happens. So much for mil-spec! glad I didnt use them in the field with deet on my hands! I think the lesson learned is not to mess with the lapping on cnc made rings and just use the aligment bars. [/QUOTE]
