Re: Lawton 7000 20MOA rail with Falcon Menace 5.5-25
If you have the scope and the rifle all you need is a measuring tape to figure out your ring height. The ring height is listed on most websites...
Just for thought though I have a lawton 7000 action with a USO sn3 3.2-17x44. I used the Burris XTR low rings and I have about 3/16" clearance between the bottom of the scope and the MTU contour barrel.
I would also say that if you do not have a good ring lapping kit, you should pick one up. I've got the wheeler lapping kit. I've found that while the burris rings are good for the money they do benifit from a little time spent lapping them.
