Went to give my new ruger mk2 a good cleaning at lunch time so I could pop by the range on the way home. Set it up to get going and some faint silvery lines catch my eye on the scope right behind the rear ring. WTF:confused: The scope had shifted.

Took everything apart and see that there's a nice coiler of scraped aluminum on the bottom of my new Nikon scope :mad: Now WTF have I done. Luckily the shavings cleaned up well with a stone and you can barely feel the gouge - probably only a thousanth or two of an inch. Lucky. At this point I'm thinking there must be some serious alignment issues but quickly figure out that the front ring is looser than hell at the base. Only the rear ring was supporting the scope after the recoil had loosened the front ring from the receiver.

I'm new to these rifles and they're ring mounting system and see now you need to tourque those puppys. Normally I have to really be carefull not to use too much strength on smaller fastenings of all type and I've wrecked/stripped my fair share of screws and bolts before. My wife is convinced I have no feeling in my hands and have the finessfull touch of a grizzly bear :eek: But low and behold this time I didn't get the fricking thing tight enough. Even though I did use locktight the recoil during last session obviously loosened the bolt that mounts the rings to the reciver up and bloody nears ruined a good scope! Anyways, just a reminder a guy should always recheck s**t like:redface: this especially when its new...

Oh and luckily it still shoots OK, so I haven't buggered anything up but cosmetics of the scope. Break in continues........

Nothing like trying to scope in a rifle that has Scope wobble. :D

Iv'e learned the hard way $Ammo$ to check the scope mount and rings every time I use a scoped rifle.:D
 
Did you use steel rings and if so did you have them lapped?
Properly lapped rings will hold a far more securely than overtightened steel or aluminum rings.

Scope Mounts are the weakest link in your sighting system... I have broken or loosened a lot of screws, mounts and rings on guns in the last year.
I have been using a Caldwell lead-sled for quite some time now. It is an awesome shooting aide from the bench. But with a hundred pounds of lead on it the gun or rifle soaks a lot of recoil.
Any weak link becomes dramatically clear after a few shots from the lead sled.
I do not recommend an aluminum base except on an aluminum receiver... use a steel base on a steel receiver... good quality aircraft grade machined aluminum rings are OK and steel is great... Talley Leupold, Burris and the like.
I would not use lock tight... well maybe the blue stuff in extreme circumstances.
Last summer we had three scopes loosen and one detach from slug guns shooting off the Caldwell....very dangerous. All the instances were with aluminum bases on steel receivers...:confused:
Make sure your screws are long enough and torque them properly when installing your base mount and rings.;)

They're stainless Ruger rings. And they didn't loosen from the scope. The front ring came loose from the receiver. If your familiar with the Ruger system if its not 'cammed' right in there there's no support at all. So, all the force of recoil was put on just one ring, which held tight. Something had to give so the scope slid in the ring a bit gouging the scope! I normally recheck scope mounts as REDD says this is the weakest link. This time I didn't (until too late) hence the title of this thread....
 
The Ruger ring system is a really good one, I liek it alot, but that is ture- they have to be on proper place!:)

I have alo found that they could use a teeny bit of lapping, to eliminate teeny high spots left from the tooling.:)

Indeed Gate. Ruger seems quite proud of their "machined matched pair" system but I found a little 400 grit made them even more 'matched' ;)
