yup it is indeed an M14 E2 stock. Rare and BIG cash if you can find one. Finding one in that condition and with it's original hardware, like the one in the pic posted in this thread....... better buy a lottery ticket instead, you have a better chance of winning than finding a mint , new condition, original m14 e2.
I do make a similar stock in fiberglass but i am not yet a registered dealer on cgn, something i had hoped to have done by now...... but will wait for the new year. My version in fiberglass is called an M14SE2, as seen in the following pic
