Anyone have any practical experience of shimming scope rings. Good idea, bad idea? I'm looking to gain some elevation adjustment from a scope and am toying with inserting a .020 thou shim in the lower third of the ring, but I'm concerned there won't be sufficient contact with the scope tube so it may move under recoil or worse, bend/damage the scope tube. Would I be better off lapping the rings? it's a 30mm scope so Burris Signature Rings are out and it's not possible to adjust the base. |

Burris do some rings where you can actually buy the shims 0.005, 0.010, 0.015 and 0.020 + and - (Burris Signature series)....I've used them with and they have been OK so far. No movement provided you clamp em tight Burris do 30mm Scope rings cos I use em on my leupold and Nightforce scopes. Shimming in ordinary scope rings causes the rings and scope to be put inder uneven stresses and I've been advised that it is detrimental in the long run both to maintaining zero and to the scope and mounts (dunno if this is true or not). I've done it on air rifles with cheap scopes but I'd rather use something designed for it. Hope it's of help  |
Try these (look a little lower down the page) http://www.opticsplanet.net/burris-zee-signature-30mm-rifle-scope-mount-rings-for-weaver-bases.html They come with +/-0.010 inserts in 30mm.....just do +0.010 on the rear and -0.010 on the front (or visa versa) and it should buy you the 0.020 you need...I've done it with one of mine and it worked for me.

No, they have all felt the kiss of the Dremel somewhere or other.........just like the car, gate, lawnmower, dog, cats, lizard, wife & kids (wife got quite worked up actually, something to do with 30,000rpm  ) .............

These look like they'd do the trick thanks. Brownells site says they only do the +/- inserts for 1" tubes though  . Do you know a UK supplier or did you order from Optics Planet?

Have a look here.... Link might help and is better than shimming!..
|
Thanks!, that would do it too. Although the cost is higher and will put the scope even higher above the bore. Burris rings are looking the best option at the moment.

| Just order the burris rings from optics planet. with the current exchange rate even with shipping and if you have to pay duty it will probably work out cheaper than buying them here - if anyone has them in stock. Optics planet are a reliable company. If you shim the rings you will mark the scope when you tighten it down,even if you don't bend it. |
Yes you are probably right................... ..done it.....now where the hell are they?

Have a look at these lot again. I've had plenty of bits from them including ARMS mounts & one of the MOA bases and never had a problem. I think it all comes down to which U.S. retailers can be bothered to get an export license from the State dept.. Brownells also do the Burris rings and you shouldn't have a problem getting then to send to U.K. either! Brownells |
That was my understanding too...If Donald Rumdsfelt can ship shitloads of poison gas to Saddam Hussein, a pair of scope rings shouldn't be too much to ask.........

Thanks again, I have another order in, if that doesn't work I'll give him a try
