Scope Adjustment SOLVED- reference for future if someone has similar problems

[Motega]

I posted last week about running out of adjustment on the dial of my Redfield TV scope mounted to my carry handle on my Bushmaster AR15. I returned the scope to its mechanical zero as suggested by a member here and re-mounted it with one ring at back and one in front. The eye relief isn't as great but I got it sighted in with no problem.
I am noticing that I have to keep tightening things and the scope rings aren't completely touching between top and bottom half of both forward and rear mounts. I need to lok-tite it I think- unless anyone has a better idea.

Anyway, problem solved, I think it was just mounted bad. I'd prefer to have it mounted far forward but the adjustment dials are such that if I mount it forward the dials must be in FRONT of the foremost ring (see other thread for pic) - this setup obviously just doesn't work.

For future reference anyone having the same problem just try returning the scope to mechanical zero by going all the way in one direction, counting clicks or measuring tick marks (mine doesn't 'click' but does have hash marks) to the opposite extreme and then coutning 1/2 the clicks or distance back. Then remount with rings on opposite ends even if you are sacrificing eye relief.
I chewed the black out of a 1" dot at 50 yards this weekend using "Tac-X" 62 grain ammo after remounting. All is looking good.

Thanks guys!!!!

If you have to keep re-tightening things, I would suggest that you get some different rings.

Also, Burris Pos-Align rings are very useful for addressing this issue.

But, as you note, re-centering is always the first step.

Yeah, you shouldn't have to retighten them, but at the same time, if I'm understanding what you are saying, you are worried because the top and bottom of the rings aren't touching and have a slight gap on the sides where the screw is? This is normal a lot of times. You don't want to over tighten them.

EXACTLY a gap THANK YOU for confirmaing this is normal... as far as tightening, I think it's more of the thub screw that holds the mount to the carry handle... are there better options than lok-tite?

How bout putting a lock washer under it?

I just can't fathom why it won't stay tight though.

I have had AR-15 carry handle mounts and even a Colt carry handle scope before and never had any problem with them coming loose.
Weaver scope ring clamps can be tightened with a coin and never come loose on hard recoiling rifles.

The rifle is haunted... I'll tell ya one even WEIRDER.. the vortex flash hider keeps coming loose!!!! that thing is designed to TIGHTEN as fired. It's a great weapon but she sure does have a mind of her own. When she is behaving it's a pleasure to shoot and sickeningly accurate!
