Sir, If I may ask a question regarding the M44 rear stock? Otherwise please direct me to who might know.
On the STG/MP 44, was the rear stock merely butted up against the rear receiver cap and screwed from within the cap; or is it inserted INTO the cap ?
In photos and schematics I seem to see both.
Thanks, IAC.

Thanks for the info Pete. We also checked the trunnions here and found a large difference between them as well. In the 1940’s they did not have G.D.and T. Infact it was due to WW2 that this system of stacking measurements came about.

More on the work on the receiver block dimensions
Measuring and checking several rear sections from cut receivers shows a fair amount of variation in the placement of the “button hole” That’s the divot drilled into each side of the rear of the blocks. They vary enough as do the barrel pin hole and the ejector pin holes that they will need to be located and drilled by the builder using the new block.
I can outline a method to “find the right place for that divot. Or it can be done using an existing block remnant that would have been removed from the cut rec.
