Yes, the pin IS removable. In fact, it comes out easily. But, one end is flared just a tad. I have removed mine several times. And the pin is reusable.
Stinger that looks like the same parts diagram I have. I will try and remove the pin what do i have to lose lol.
The pin as described is tapered with knurling on one end. I was able to use a punch and tap it right on out without fuss. New barrel breech seal o'rings and a minor damaged part is on its way.
it aint junk unless its kinked
Tonights progress and the name of the gun is Wookie.
