Mag well measurements will tell you that. Yours is a 30'06. You got it at a good price for sure, You could always part one together or sell it for 20 or 30 bucks for a fast turn around.
Cool...by my name you would think i should know small arms but i don't. Bombs and Missiles were my AFSC in the Air force.
I would build a 770 for cheap, all parted out cheap over time. Then take that stock and do something really not practical for anything at all. Build some crazy looking Google Gucci gun that operators would laugh at and airsoft folks would dream about. Then take it to a gun show and find that one tard who has more money than weaponry sense and allow their imagination to spend that money.
But thats me, I have more weapons than there are words in the Bill of Rights.
