Presently, I own three 10/22's. 10/22 #1, is slightly modified- quick bolt release modification and threaded muzzle 16.5" barrel with 1/16 twist with after market stock. 10/22 #2, slightly modified- quick bolt release modification, threaded muzzle 16.5" barrel with 1/9 twist for Aguila 60 gr ammo, in a factory stock, and 10/22 #3, well, the only thing stock is the ten round magazine. You'll find that the extent that these rifles can be modified is limitless.
The two images of the rifle with the black stock is the same rifle- left and right sides- and the final look of the rifle is slightly different- no iron sights and the scope and mount is different- but similar look. The rifle with laminated stock is a build with all aftermarket parts.
