There all different but the same as each were done by hand by different 2112’s. If you can wait a few days I will post you up some pics of mine.

Here's a pic, and I will note that each bottom metal plate was hand-fit to the rifle so the final length and small notch cut for the release was done after everything was mocked up. Here's my spare bottom metal piece from a retired 2112, but he didn’t do the final notch cut (see arrow) or trim it the exact length (corners are not yet beveled as seen below), as I didn’t have a spare stock for final trimming. Correct screws are shown as well.

I have not seen "specs" per say, and my understanding is that this was done in the late 1970s by hand. I have seen some subtle variations re the bevel at the corners and related notch cut.

John,
All they did to mine was to shorten the end next to the trigger guard and re-cut the bevel where the plunger engages the bottom of the floorplate . Pretty simple modification.

Steve,
If it's for a short action 700 I think you will find that the front screw hole in the trigger guard was removed and a new hole drilled along with a bushing put in the stock. I have these pictures but no solid dimensions to modify.

Not sure if they cut the trigger guard or not. I seem to recall there was a screw in front so, they may have relocated it and used an ADL type screw in front. Can't remember for certain. Too bad I sold mine or I would let you look at it.

Edit, you may be able to get the spacing for the front screw by measuring an ADL type trigger guard. I measured approx. 2.75" center to center for the holes on an ADL trigger guard I have.

According to the M40A1 build guide over on Sniper's Hide, they say they did have the front trigger guard screw. The magazine box was TIG welded to the receiver as I recall.

Overall length of mine is 3.258". I will also note that the milling for the M700 trigger unit was enlarged on this piece, it has a scallop cut. This might have been a later refinement on M40A1s, but I didn't compared it to my take-off stock which is now bedded, etc.

Best guess re hole spacing, center-to-center, is approx. 2.67" to 2.68".

Hope that helps.

Those pictures look familiar.

Wouldn't it be cool to have a thread for how to modify each part for a M40A1 build?

There is a thread with 1800+ posts re M40A1 build guide. (not all is correct, but just an fyi):

M40a1 build guide

Well a couple of you have asked for a build guide for our M40a1 take off stocks. I am building an accurate clone, and learning as I go. I am by no means an expert, but I'm trying to find the right information just like many of you. Please post if it directly pertains to a the topic at hand or...

Thanks to all that responded, I think I can at least modify the trigger guard and then do the floor plate once I get the stock

Seems everyone beat me too the punch, here’s mine.
