I bought a replacement inner magazine tube for a .22 pump rifle and I need shorten it a bit. I have removed the catch pin which I thought would be holding the knurled knob, spring, and plunger in place. Then I was going to cut that end of the tube to length, drill a new hole for the pin, and shorten the spring. That was the plan, but the knob will not come out with the pin removed. Is the knob normally pressed in the tube? I thought it might have loctite, so I heated the tube with no luck. Anybody know how these are normally put together? Any ideas how I can get it out without damaging the finish on the knurled knob? I thought about cutting the tube with it assembled then driving the knob out of the piece. I would have to cut it off near the knob because I will probably cut the spring also. I could then cut it again at the right length with the spring out so I don't end up the spring too short. Sound like a plan? Any better ideas?
Thanks!
Thanks!
