Alright I have my M1A scoped, it does well but I have noticed that the scope is mounted wrong. The Cross hairs are cockeyed, or in other words I messed up when mounting my scope. I have now tried about 8 or 9 times and its never perfect. Any tips or tricks?
 
Well, if you over-obsess about it, it'll never seem perfectly straight. Trust me. lol.

Just hold the rifle out in front of you a bit, but to where you can still make out the crosshairs, and try to line it up that way, looking down the stock.

When tightening the ring screws, do 1/4 turn at a time on each screw.

True.
You could get all funky with putting it in a machine and whatall but only your eye will be behind it.. see, literally, what looks good. Yer own sef.
 
Perfect might have been the wrong word to use. I'll have right until I have to tighten it. Then it always seems to pull it one way or another.

Loosen all (4 or 8, depending on your rings) screws and cant the scope whare you want it to be. Put the top half of the rings on, with equal gaps on both sides. Tighten ALL the screws until they barely touch the ring tops and then start an alternating pattern (FL,BR,BL,FR for example) only turning each screw 1/8 turn until they are all tight.
 
Use a feeler gauge between ur scope and base. It's the best way square your scope up with ur rifle.
 
so there are several problems here potentially... the annoying one is that often, even in high dollar glass, the crosshairs are not actually square to the scope body.

the important thing though, is that they track. so get you a poster board and sharpy and ruler and draw some thick crosshairs on the board and mark off 1-10 mils or 1-30 MOA or whatever your scope does. hang the poster board at 100 yards or whatever distance you marked off the lines in and level it. then level your rifle in a rest, with the scope mounted as best you can line it up. hopefully, the reticle in your scope aligns with the lines on the board. if it does, twist the knobs all the way up and down and see if they still line up. if so, you're good. go shoot. if not, adjust the scope until it does work. if you can never get the scope turret movement to align with the reticle, then send the scope back
 
OP:

It's simple. Get yourself some "feeler gauges". Determine the distance between the flat bottom of the scope's turret, and the top of the rail. Insert the feeler gauges while you tighten the screws equally on each side. Use a torque wrench. The crosshair will be flawlessly level. Remove the feeler gauges. You're done.
