Noticed this yesterday while I was removing my dust caps. The mount is able to slide along the top rail in direction of bullet travel, Side to side movement is nill. Is this going to be a problem? I was thinkning of making some shins to stop the movement. Do you think this is overkill as Grop size great for this type of rifle.

This has been seen MANY times. Basically the lever has become stretched out and once this happens you are SOL. Contact ARMS for a replacement.

streatched only after being relocated once. What would that be a total of 3 times the arm has moved. close open relocate close.

I am thinking clamping pressure is not enough, From your link seams if i try the wegde those min parts will fail.

rifle is only for 3 gun. I will need it in less than a month for Maryland 3 gun. Think I'll pack a spare rifle this time instead of just parts.

It doesn't matter how many times you opened or closed the lever. It can get stretched out just sitting on the weapon.

I think if a lot of people tried to move their ARMS mounts (that have NEVER been taken off of their weapon) they would find that they are loose.

If you want an adjustable throw lever for your Aimpoint, take a look at LaRue Tactical.

I have one flat top that ALL my ARMS stuff is loose on; the same stuff is ok on all the others.

Problem is, as Grant says, you're only option is to send it back to ARMS and see if they can send you a tighter one. Depending on the upper, though, that might not help.

Well it is a Colt after all!

Well I did not want to blame the upper. When I posted on the Al finish and anodizing issues, it got a little warm. So yeah my upper can be out of spec.

edit, Is that the STD LaRue mount in you pic, C4?
