So I see these "mystery" fiberglass oversize stocks come up for sale from time to time. Look like dead ringers of mcm m1a stocks. Owners never know what manufature they are. Only info I can turn up on makers is mcm, usgi. Anyone have an idea? Thanks and sorry if this has been postedbefore.
I have a stock that fits that description; I picked it up from someone who did not know where it came from. I stripped the paint off and refinished mine. The Stock is Fiberglass construction, and it appears to have 3-layers of fiberglass in the shell. This is a very sturdy stock. I don't think it's a McMillan because it did not appear to have a gel coat, and the interior looked like it was molded with fiberglass cloth in the inletting rather than CNC'd like the McMillan's Iv'e seen. Mine was inletted for a Double-Lugged Receiver and previously bedded. I removed all of the old bedding, resurfaced the top to fit a Sprinfield Loaded model and filled in the rear lug recess.
Mine looks and feels like a Boyd's Type II, but in fiberglass.
Seems to fit the MPI construction description and pictures, but I have never knowingly handled an MPI stock so I am only guessing and comparing pics and info on their website.
Also, It does not seem to fit the Bell & Carlson construction description, but I have not handled one of theirs either.
