I would like to sell a Choate Mk5 tactical pistol grip stock that I just took off a brand new Mossberg 930 SPX. May fit other models? Super easy install, you would only need your old recoil spring retaining pin. Lop is supposed to be 13 inches. I will include the recoil spring, tube, spacer, nut, and the factory shim pack that allows you to adjust the rise. I can ship if needed, buyer would pay shipping . I can accept Pay Pal. $60 takes all.
