I decided not to scope my M1A...
3rd generation mount. Marks on the rail from rings that were installed, some slight marks on the scope mount from one of the locking knobs that was floating free in the bag.
Mounted on rifle, but never used, so I cannot comment on the mount's ability to hold zero.
I paid $90.00, I would like to get $50.00, or trade for AR/AK/FAL mags.
