Fellow Hiders -
I'd like to give a big "thumbs-up" to <span style="font-weight: bold"><span style="font-style: italic">Cameron Murphy at Murphy Precision</span></span>. Cameron is the proprietor provides excellent product with fast turnaround. Hes' also a really nice guy.<span style="font-style: italic">"Thats' nice, but I've already heard that"</span>, you say?
Well, my experience is different for several reasons. For starters, my particular base is the first of it's kind from Murphy Precision - a two-piece base. The typical base that 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.
Given the smaller loading ports typically found on rimfires this is a serious consideration. Cameron asked me to provide him with a receiver layout diagram with the dimensions of the loading port the screw locations and centers, which I did. I also sent him the original Kimber two-piece base and screws so that he could match the contour exactly and calculate the length of the new screws correctly.
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).
Another thing is that Murphy usually make bases in 20 MOA, but I requested that my base be 25 MOA. As I like to be able to dial out as far as I can without holding over I wanted to squeeze out an extra 5 minutes. The rear height differential between a 20 MOA and a 25 MOA base is negligible.
Lastly, my base is made for the old Kimber of Oregon Model 82, specifically an 82C "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 82B is the same as the 82C, and since I'm really pleased with the 25 MOA two-piece base that Cameron made for my 82C "Roundtop", after I try-out my 82C base I'll probably have Murphy Precision machine another 25 MOA two-piece base for my other 82C "Roundtop".
Not too many guys here have Kimber Model 82s' and even fewer have Sporters, 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".
