We’ve designed our SKS Detachable Magazines with serious shooters in mind. The mag body, made of high strength composite, has horizontal grooves cut into it for an enhanced gripping surface. We’ve used the highest quality interior components and incorporated a metal floorplate so you can expect maximum strength from this magazine. That, plus the fact that this mag is made in the U.S.A. so it counts for three compliance parts, you could say we’ve really thought of everything. Counts as 3 U.S. 922r Compliant Parts.
