I have a nice Browing Challenger that is giving me a problem-I cant get the barrel back on- there is a bit of overhang at the back. I have gotten it on before with no problems-but this time the barrel doesn't lock up. Also while fiddling withe unit-my extractor, extractor spring and plunger - made a leap for freedom across the room! How easy is it to get the extractor unit back in the gun.
Ideas anyone!

Thanks-Chances
