I just received 3 custom rails (for Rem 700 LA) made by Fenton Sandlin of Alba , Texas. Fenton is a great guy and will custom make any rail you want. He charges $65 + Shipping.
I don't know what the difference between in height front/rear of of a rem 700 LA rail is. Measuring a couple of my B-Square and a weaver I came up with .11"
Using the .11 figure, I computed the MOA of my three new rails as 105, 89 and 65 MOA. I also had Fenton open them up for #8 screws (as Kirby sends all my guns with #8's). The craftsmanship is superb. I'm going to order a 75 to round out my collection.
I plan to use these with my 5.5-22x56 NXS and 5-32x56 BR NF scopes (all with NP-R2). Given I have 10 MOA hold under, 25 MOA hold over (about 95 MOA and 50 MOA scope adjustment) - I should be able to (loan one of my guns to Kirby, uncleB or GG) get some long range hits.
A bug in the forum software prevents me from hot-linking the pics, but you can see the rails HERE
I think the ultimate optic solution is my 8-32x56 NF BR scope with 1/8 MOA turrets matched with the appropriate rail. At 2,000 yards, that's 2.5" per click in lieu of 5" for a standard 1/4 MOA.
BTW - right now I don't shoot PD at less than 800 yards [img]/ubbthreads/images/graemlins/smile.gif[/img]
