The Sa vz. 61 Commercial Version in .22 LR retains the same feel, appearance, and operation of the military issue vz. 61 in 7.65 mm Br. High strength polycarbonate is used for all magazines which yields an incredible resistance to wear and impact. Magazines are available in both 10 round and 20 round capacities and activate the bolt catch when the last round is fired. The Czech Small Arms .22 LR Sa vz. 61 remains true to the original design. Enjoy the plinking!
