I have Leupold Mark4 rings for my nightforce going on my AR-10T. Nightforce says if I don't use a lapping bar to ensure my rings are straight I'll void my warrenty. Should I worry about that with my setup? I would think the AR-10 upper is straight? I can't find anyone locally with a lapping bar, any suggestions?

I have always used a lapping bar to mount my scope on all of my rifles. If you do a search, you should find one for under $30. This cheap compared to a $1000 scope. You first use the bar to mount and align the rings. You really shouldn't use your scope to do this because you run the risk of scratching or damaging it!! After you have torque down the rings, then you use it to lap the rings. This assures everything is inline!! Stuart p.s. I use mark4 ring with my NightForce NXS [img][/img]

or, you could go with Badger rings. No need to lap those babies. Joe

I lapped my Badgers on my 700. And I was glad I did, they were not as perfect as what you might think. Check out [url]www.sinclairintl.com[/url] , that's where I got my 30mm lapping bar for about $30 or so.

I ordered one from Brownell's. $45 comes with compound. I think the Mark4 rings are at least the same quality as the badgers. I was going to get badgers, but couldn't find them locally. Nightforce specifically says you'll void the warrenty if you don't lap. I don't know that they could determine if I did for sure, but that leads me to believe it is a common enough problem to void warrenties.

Yup, my Badgers are on the Badger one piece base. The first pair I had, did not need lapping. But my second pair did for some reason. They weren't as bad as most rings tend to be, but they definately benefited from a little lapping.

From what has been said here, I have the impression a one piece base/rings unit like the Armalite should need no lapping at all as it's "inline bored" at the factory? --RR
