pump action 500c mossberg question

[usmcchiang]

I have a mossberg 500c 20 ga pump action shotgun that has the thread of
the mag tube broken to the receiver... any ideas on how to get this out so i can replace it with a new mag tube?
thanks.

The tube broke off and the threaded end is still in the gun?

Several options.
One, try to borrow or rent a LARGE screw extractor.
Tap, (not beat) the extractor into the tube and turn it out.

Two, use a SHARP center punch to reach into the tube, and tap with a hammer. The sharp punch will "dig in" and you may be able to get the tube to turn.

Three, make up a extractor from a section of steel or aluminum plate.
Taper the plate and sharpen the edges. Tap the plate into the tube so the sharp edges grip, and turn it out.

Four, get a piece of wooden dowel rod and epoxy it into the broken off section. Use the rod to turn the tube.

Five, take it to a pro gunsmith for extraction.

I would take it to a smith, he otta be ale to pop it right out. Id be wary of doing it my self, mossys have aluminium recievers, and even thought its hard T6 id be worried id mar the crap out of it.
