I'm hoping someone here can answer this for me. I bought this stock from Numrich many years ago. It was listed as a 70 target and I was going to use it for a pre '64 HP build. It looks like some of the other stocks with the exception of the pistol grip cap to me. What do you think?
Adding more questions, This has a "repair" piece of wood on the bottom of the forend where I think a short rail would have been. If yours has a rail, how long is it? The bottom of the stock has the holes drilled already for a sling swivel. The length of the entire barrel channel also looks like it's either been bedded or epoxied. Is that normal?
You want to check the action length, as the post 64 is about 1/4" longer than the pre 64, so the stocks will not interchange, but can be reworked if you really want to use one on the other.
Also, there were some post 64 Model 70's used, that were gotten from some PX's and reworked, before the M40 was finally in the system.
