So I wanted to build a clone of the M40 USMC sniper rifle for the vintage CMP sniper matches and multi purpose role and have been researching it on here and various forums and have learned a whole lot in a short amount of time. After seeing some reviews here of other members using EBay user Beever156 M40 stock; I ordered one for myself and from the previous users of this stock; I knew I had to modify the forend to match the contour to make it look as orginal as possible. Thanks to @USMCSGT0331 info on the stock and pretty much entire build spec, I was able to make comparisons. These are my measurements (mind you human error/accuracy of calipers/measurements at the exact right point) compared to the real deal. Not sure if this helps anyone but I’d figure I’d post it. There are some measurements I left out because I couldn’t get a exact point on measure on my stock.

Now to begin the sanding phase of the build.

Link to builder guide to the M40:

A. Length from the front of the recoil lug to the tip of the forend
Orginal average-10.080 Beever156-10 3/4

H. Width of the stock at the tip of the forend (right before it starts to taper off)
OA-1.369. B156-1.514

I. Width of the stock at the front sling swivel
OA-1.512 B156-1.641

J. Width of the stock midway on the forend (4 inches from the front of the recoil lug)

K. Width of the stock at the front of the recoil lug
OA-1.851 B156-1.780

L. Width of the barrel channel at the tip of the forend (right before it starts to taper off)

M. Width of the barrel channel at the front sling swivel
OA-0.985 B156-0.985

N. Width of the barrel channel midway on the forend (4 inches from the front of the recoil lug)
OA-1.011 B156-0.999

O. Width of the barrel channel at the front of the recoil lug

X. Height of butt

Based on your measurements, the Beever stock is not all that far off.
Yup, the inletting is pretty close which is a relief to me…. Just the forend that needs the most work as a few members have mentioned before. But to be honest, depending on how picky you are, the stock profile itself looks pretty nice! I’m planning on getting in pillared/bedding before i refinish the stock with RLO.
