Re: Why NOT a 20 MOA picatinny rail on a 22 Long Rifle

Will give Murphy a shout tomorrow.
What were the costs and turn around time, if you don't mind?? They do not have Anschutz listed on their website.

Definitely give Cameron Murphy a call - if he hasn't made what you need he can always make it for you. Last year I had Cameron make a 25 MOA two-piece base for a Kimber Model 82 .22LR for me. Cameron had never made a never made a two-piece base before, let alone a two-piece base for a Kimber Model 82, so he asked me to send him a simple diagram of the Model 82's action layout including the screw hole locations. While I was at it I sent Cameron a two-piece Warne base so he could reverse-engineer the radius need for the underside of the action exactly, as well as the base screws so he could calculate the length of the new screws I'd need to use with my new base.
The typical base that Cameron machines is a 20 MOA one-piece, but I wanted a two-piece for two reasons: First, two-piece bases provide better access to the loading port and breech than "bridge" designs, even if the "bridge" is radiused/relieved for clearance.
Second, I didn't want the "tacticool" look of a one-piece design (of course, this concept goes out the door if you mount a PMII 5-25X or something equally large, but if you mount a "normal" scope the base is rather inconspicuous).
My base is made for the old Kimber of Oregon Model 82, specifically an 82B "Roundtop". <span style="font-style: italic">Theorietically</span>, my new base could also work on an 82A built with a "Roundtop" receiver instead of the dovetailed receiver usually seen on the 82As', but theres' no way to confirm it without having an 82A "Roundtop" to measure, and I don't have one.
The layout of the Model 82C is the same as the 82B, and since I'm really pleased with the 25 MOA two-piece base that Cameron made for my 82B "Roundtop", after I try-out my 82B base I'll probably have Murphy Precision machine another 25 MOA two-piece base for my 82C "Roundtop".
Not too many guys here have Kimber Model 82s', but now that the groundwork is done maybe some other Kimber guys will benefit from Cameron's hard work and machining skills. A set of correct length stainless steel screws were also provided with my new base. Below are some photos of the base on and off of my 82B "Roundtop".
