I picked up a no name scope mount at a show last week and I finally got a chance to mount it. It mounts on the side rail using 3 hex head screws.
I put on top a red dot scope that I picked up at Bass Pro a few years ago (the red dot was previously on a .22 that I used for squirrel).
Set up at 25 yds and after 10-15 shots I got it hitting where I was aiming.
Put up a new target and backer paper on the OSB target stand and went back to 100 yds.
Fired 5 shots and looked through the spotting scope, nothing. Walked out to look, nothing.
To make a longer story shorter, I had full down elevation dialed in, I ended up aiming at the bottom edge of the wood and I was hitting about 2 inches (yes that is right) from the top.
I strapped the rifle in a cleaning vise and leveled the barrel. I then checked the level of the scope and found it to be angled down in front.
The scope had integral mounts so I can't shim the back up to adjust, the mount is fairly hefty so I don't think I can "tweek" it any.
So that leaves me with repositioning the mount rail on the receiver. Can that be done? I work on aircraft so riveting is no biggy, just wondering about if this is my only solution or am I missing something.
So your rail is probably about 1/4" lower at one end than the other?
It can be done; I had a smith actually weld mine and parkerize my SAR2. The build it yourself forum guys can give you more help on how to approach the rail job.
