AR's, AK's, Silencers /Class III
Installed a red dot sight on my ar 15 decided in a emergency situation it was to much trouble went through my junk and found a 1.5x4.5 scope. Mounted the scope with the rings I had and it was much to low. Ordered a 3/4 inch riser and bingo it was ideal. Now the problem is I can't bore sight it...
