Not every Mauser fires a big military cartridge. This one is a .22 LR single-shot bolt action with a 27-inch barrel, and the seller calls it a very heavy bench gun. Weight is a virtue on the bench, because it settles the rifle and helps you shoot tight groups.

The seller says the rifle is in good condition. There are holes from a mounted scope, and the scope is not included. Those holes are a practical detail for you. You may need to find a matching base or drill and tap for a new one, and a gunsmith can sort that out in short order.

A .22 LR target rifle is an ideal tool for teaching marksmanship. Recoil is almost nonexistent, ammunition is cheap, and a long barrel makes the sights easy to see. Add a decent scope and a pair of rings, and you can practice for hours without spending much.

Check the bore and the crown, since accuracy lives there. Look over the stock for cracks, and run the bolt a few times to feel for roughness. Test the trigger and the safety before shooting. It is sold as described, in used condition. The rifle ships to your local FFL dealer, where the background check is completed.
