Gun smith long range shooter - Volquartsen Firearms VS3 Recoil Rod Spring and Assembly Kit for Ruger MKII, MKIII and 22/45

The parts work well as advertised the only thing you need to do before installing the parts is too polish the rod your spring rides on so it doesn't bind anywhere during cycling.On some of the reviews they said they had too file down places on the part too make it work. 99 percent of the time it's not that it's the spring binding on the recoil rod. Mine bound up when i first put it in the gun i removed it sprayed dye on it tried it again removed it looked for marks of where it was hitting it wasn't it was the spring binding on the rod.
