Got another question (lapping rings)
« on: March 04, 2011, 02:17:30 PM »
How many of you guys lap your rings? My last set of new rings scratched a scope for me and now I'm kinda worried it might happen again.

On those rare occasions when I don't use Burris Signature rings I lap them. It might not be necessary with premium rings but with the standard run of the mill rings most folks buy I sure would.

Would you consider Leupold dual dovetails premium?  I have lapped some and not others, and never scratched a scope or seen a difference in performance.  I always buy Leupolds.  Don't like the clamp-on weaver style stuff.

I almost always use the signature rings but sometimes the cheap side of me comes out and I buy the standard Zees. Do you guys use a store bought lapping tool? If I have to spring for a tool I may as well buy the signature Rings. Thanks for the help.

I have a Wheeler kit in both 1" and 30mm.  The stuff that I use for rings and bases are pretty good and almost never requre lapping.  I have had to lap Burris XTR rings before, but never my Nightforce/Leupold/IOR stuff.

you can buy the best rings in the world and it still could be nessisary. the reason you do it for the most part is the lack of precision the gun makers use in drill the holes for your bases.

My only gripe about the Burris Signature Zees is they don't offer them in low, so I use the standard Zee rings and lap them using a Russ Haydon lapping kit, probably one of the best buys on the net at $24.95 plus shipping.

I have never lapped any of the rings that I have used.  I have probably used all of the most sold ones in WM, Bass Pro, Cabelas, local pro shops.  Most that I have now are Leupolds and Millett.   Maybe I needed to but never heard of the process.  In a nutshell what do I need to look for to determine if I should lap them.

You won't know what to look for until you lap one! You can't see the problem. What happens and I don't know why but when the rings are made they aren't perfectly round on the inside. A lapping rod goes in place of the scope, you put some grit on the rod and procede to push, turn it inside the rings. At first it is tough to get going, but the more you "stroke" it the smoother it gets. After a few minutes and a little more tightening on the rings they are good to go. After you clean the grit out of the rings you will see why EVERY (except sig. zee rings) set of rings needs to be lapped. They are now truly round, giving the rings more bite against the scope tube. A out of round set of rings can actually dent a scope tube. At first I was a bit skeptical but I have now lapped 4 sets of rings from Warnes to Weavers and all were out of round.
A person can make their own lapper kit but I say it's just as easy to buy the kit, plus the kit comes with a torque driver & bits, 1" rod, 30mm rod, cd instructions and a tube of lock tite.
