These are laminated "BDL" style stocks, checkered, new factory production. Finished drop-ins for most commercial Mausers including Remington 798 (these are Remington OEM 798 stocks), Interarms Mark X Parker-Hale 1200 Charles Daly, etc..
Remington discontinued this model and we got all the extra stocks available in this week. If you have the 798 SPS or other commercial Mauser it's a great way to upgrade to the better model on the cheap. Military Mausers need floorplate and other fitting, commercial 'Mark X' versions noted above reports to be great fit out of the box. There's a few unfinished units for $69 also.
