What kind of adhesive to use on a slipping scope?

I recall a Ross Seifred suggestion that used some kind of gasket cement.

I can tell you what has worked quite well for me.

First,since I have made a practice of using a chunk of OD ground .995 dia steel barstock( made to feed swiss turn machines_) and 320 clover to lap my rings as they sit on the mounts,I have not had a problem.

I have put a drop of green cylindrical fit sleeve and bearing retainer loctite in the lower saddle only,not the top ring half.

That holds.When you go to take them back apart,a very small hammer is enough.
 
If the ring is not coming down and touching the scope just milling off a little from the flat bottom of the top ring should bring everything together. A small smear of abrasive powder will hold things and keep from slipping.
 
hooligan1:Actually the "blue Locktite" is the way to go,,,,, only after you hunt down the manufactures suggested torque settings. Leupold prints theirs right on the ring package so there will no mistaking it. As far as tape goes, throw that crap in the trash man. The easiest way to get proper mounting techniques ito read or go on the internet to "You Tube" and look up Midways "How to" videos....... I have never seen anybody use any kind of tape, because with the proper techniques there is no need.

Roger that!!!!! :)
 
Thanks for all the replies guys.

I'm going to take it apart, clean it real good, and use the LockTite on the rings. I don't think any type of shim is necessary at this point.
 
you can buy something called carbon prep paste used in high end bicycles. It is basically a grease with tiny glass beads in it used to stop seat posts from slipping. Works like a charm on all kinds of things I cant keep fixed. they sell it online and most bike shops carry it. Me personally i would get new rings but I can promise you if there isnt dayling between your rings this stuff will work.
 
Scope Slippage

Good afternoon. I had this problem with my Desert Eagle. I fixed the problem by machining a sleeve that was the same inside diameter as the scope tube and the length from the scope adjustment turret to the scope ring in the direction of the slippage. I made it in 2 pieces and screwed it together just like your scope rings. I absolutely guarantee that this will stop any scope slippage. It also doesn't look bad if you do a nice job. I own a machine shop, so if you cannot get it made locally, just send me the dimensions and I will make you up a set, cheap. Best of luck. DennyMac
 
Do the slippage marks go completely around the scope tube? From the picture it looks like they stop at the top. If they do stop and then continue somewhere else the rings could do well with a lap job. For years I just put a drop of nail polish in the bottom ring. Later when takening the rings off I still had to tap the scope free of the polish even after the top of the rings were removed.

The best condition you can have between scope tube and rings is 100% contact. Lacking that, lap the rings to increase what contact you have. Some kind of liquid (lock tite, finger nail polish, rubber cement) will help lock down the scope as will using the correct torque.

Oh also as others have said make sure the rings and the scope tube is oil free.
Good Luck

I have to tell you that before I would start messing around with nail polish, LockTite, electrical or friction tape or any other Mickey Mouse way of fixing this, I would start by trying to find out just what exactly is going on.

Assuming that the scopes tube is actually one inch in diameter, I would say that the rings are not aligned correctly. First off, what brand of scope, rifle rings and bases are these and what caliber is this rifle. Who did the mounting?

I would take everything apart and start from scratch. Clean all screws and threaded holes with acetone to remove any dirt, thread locker and oil. Ditto for the scope's tube and the inside of the rings. Reinstall the bases and use blue LockTite on the screws. Mount the lower half of both rings. At this point, install a ring alignment tool, install the upper half of the rings just snugly and check for alignment. I'll bet a dollar to a doughnut this is where your problem is, especially if the rifle is not chambered for a round which is a big kicker. If you do not have the necessary tools and considering what has transpired already, it's time to seek the help of a qualified gunsmith. If you do have access to the ring alignment tool, do what is necessary to bring the rings into alignment. After you have accomplished this, remove the top half of the rings & the alignment tool, insert the scope, attach the top half of the rings and tighten evenly but do not over tighten. Absolutely do not use any kind of material or adhesive inside the rings or on the ring screws. Do not arbitrarily just lap the rings but be sure that both the scope tube and rings are totally free of oil.

The fact that the ring halves are not touching when the screws are tight tells me that neither the rings are oversized nor the scope's tube is undersized. Mounting a scope is not difficult but it takes more than a screwdriver and/or hex wrenches to do it correctly. Although anything is possible, I'd say that probably 90-95% of all scope and sight-in problems are due to incorrectly mounted scopes and the vast majority of those problems involve incorrectly aligned rings. Even if the scope isn't sliding around in the rings, if the point of impact is not moving on target corresponding to the number of clicks of the turret, the odds are that the scope is twisted in the rings binding up the erector system. I've seen it dozens of times while working at my gun club's sight-n clinic before the November firearms deer season. Usually a quick trip to the on-site gunsmith solves the issue if the equipment is if reasonable quality.

Anyway, the very first thing to check is the ring alignment after you determine that the bases and ring lower halves are mounted tight. Do yourself a favor by not trying to "Red Greene" the rifle and optics together.
