This six-position, recoil-compensating collapsible buttstock kit requires no fitting for most stamped AK-47/74 rifles and is perfect for Saiga shotgun conversions. It fits AK rifles by using a unique receiver block that expands to perfectly fit stamped receivers when screws are tightened. It has six (6) attachment points for single point, 2-point, and 3-point slings along with battery storage compartment for two CR123A 3V lithium batteries or two AA batteries without allowing rattle. It is made of Mil-Spec reinforced polymer composite with steel hardware, and rubber buttpad. This kit includes the tube.
