Air Gun Home :: View topic - Ruger airhawk scope

I have a new Ruger Airhawk purchased at big 5 sporting goods. For awhile, i used the irons to plink in the backyard.

Time to mount the scope, says I!

I set up the rifle in a fixture, affixed the mounts with the rear one up against the stop thingie. After leveling and eyeballing, I placed the scope in the rings. Using new 4mm machine screws (the ones that came with the scope were, um, crap) I got er cinched down, lock-tighted everything (blue) and sighted her in.

I used a pencil to put witness marks on the scope tube fore and aft of each ring so I could ascertain if there was any creep present.

After 10-20 rounds thru the rifle, the scope has slid to the rear about .050" and now I don't know what to do.

I'm about to chuck the scope and stick with the irons (fiber optic sights).

I'm afraid that if I keep torquing the ring-screws, they're going to crimp the tube.

What do you all suggest this newbie-to-airgunning do?

Thanks, in advance!

Invest in some decent Weaver rings.

Seems you haven't got alot of choice but to tighten the rings a bit more. Remember to tighten the screws in a criss-cross pattern so as not to load one side up vs. the other. You may want to think twice about loc-tighting something before being sure it's tight enough.

You likely won't bend the tube, more likely you will strip the threads out of the mount before anything else.

Good luck, and Welcome to AirGunHome.com

You can get some THIN double sided tape. Just a bit will do, on each ring. Double up on one if you need a "shim" slightly.

Don't use glue or anything, you can damage the tube that way. The tape should peel right off or maybe take a bit of goof off to get the adhesive.

Somewhere I read that you can take a bit of automotive paint rubbing compound and paint it on the rings. The little bit of grit is supposed to keep things from sliding. Maybe worth a try.

I now have a number of excellent ideas to try. There is hope!

Thanks again!

I let my scope (I have the Ruger Air Hawk, also) come to rest against the rear scope mount and it worked great.

Then I bought me a TF 89 with a TF 3-9x44 AO air rifle scope. I liked the scope so much that I bought another (used one for $40) for the Ruger. Put it on the same way, resting against the rear mount, and it has been dead on.

At 25 yds, will a good rest, I can shoot the little white tops off plastic coke bottles all day long.
