SEALs uses them, but not too much is known about the rifles. There are only a few original SEAL used stocks floating around in private collections. I've owned 3 of them and they're the only 3 I've ever seen. 1 black, 1 green and 1 tan. At least one of them, if not all 3, use an "L" shaped recoil lug like the Mk13 Mod 0's have. The stocks use a Remington 700 long action receiver, probably with a "B" or "C" serial number prefix. The rifles are chambered in .300 Win Mag and probably had a Douglas barrel, since that's what they were using on the pre-Mk13's and other rifles at the time.
This is why the Vintage Section is the best forum, more information that you won't be able to find anywhere else!
Here's the tan stock, it's awesome! The stock still has it's original sniper paint and I paired it with an original SEAL used painted barrel (not matching camo). The barrel appears to be an actual Baker Special barrel, since the unpainted portion on the underside is the exact same dimensions as the stock's forend. The camo paint is different, but I'm 99% sure that the barrel came off a Baker Special. This is the only original stock/barrel set that I'm aware of, so the new owner is extremely lucky to have it! All of my Baker Special stocks and the painted barrels came out of Crane long ago and I trust the source, so they're legit.

The barrel is only marked with the last 4 digits of the receiver's serial number, the serial number pic is one of my M91 barrels (I didn't take a pic of the serial number on the Baker Special barrel, so this is a stand-in photo for the missing pic, it just gives you and idea of what the marking looked like). The other 2 pics are the Baker Special barrel with what appears to be an original SEAL used RAD M91 barrel. I have 3 of these possible M91 barrels, all 3 are painted and are possibly war used. The 3 M91 barrels are available, in case anyone wants one......

3 possible M91 barrels are for sale, buy all 3 and you can screw the legs to brackets attached to a seats, and you'll have the world's most awesome stool! I've checked the unpainted area with a variety of original sniper rifle stocks, they dont fit anything that I have in my collection (M83, M24, Mk13, etc.), so all we can think of is the M91. They each have the last 4 digits of the receiver's serial number stamped on them and all 3 are chambered in 7.62x51.
