Gunsmithing McMillan (Order) Stock Spec Help...?

[Bushpig]

Hey Guys,

Wondering if anyone can help me out with this…

I’m in the process of ordering a custom drop in stock from McMillan (an HTG for a Remington 700) and am having a difficult time nailing down the specs for the barrel contour inlet. When I spoke with one of the girls at McMillan, she asked me what “cylinder length” I wanted on the stock. I have a Rock Creek M24/M40 contour barrel blank that is going to be used on the build. I understand that the straight (cylinder) portion at the chamber end of this particular blank is 4” long. I plan to have a Holland oversized lug put on the rifle and would like the finished barrel dimensions similar to that used on the M40a1 (1.20" X3" +/-, straight tapering to .920-.940 +/- at 24”). Now, my question I guess, is should I specify a 3” cylinder on my stock or should I go shorter at 2” and just have the smith open the barrel channel up to accommodated the finished barrel - if required? Any informed assistance you guys can provide would be greatly appreciated. Thanks in advance.

Just order it 1" shorter than the flat at the breech.

So, given the unfinished M24/M40 blank has a 4" flat (at the breech), I should specify a 3" cylinder? Thanks much for the assistance wnroscoe... I want to make sure I've got it straight so I don't mess up my order.

Cheers,

Thats correct. McMillan has started calling gun builders and confirming this as well. Since I never cut any thing off the breech I just deduct 1" for the threads and under the recoil lug.
