B&T MP5K collapsible buttstock . This fits ONLY the K model ! It’s 2 pin mount . New , mounted , fired a mag through it . It’s brand new . It’s a nice buttstock , but I’m old and it makes me twist my neck uncomfortably . Young guys wouldn’t be an issue . I have the Gibbous aftermarket butt pad , which is a really nice improvement ! No trades. Price is firm . Below market , not sure even in stock lately . Thanks ODT .
