Hello all, my first post. Happy to be a part of this forum. Hope I can answer some questions to help someone else sometime, have learned alot of good info here already. Seems like a great fourm. Now my question to the experts. I have a westernfield M550 shot gun missing some parts, like the bolt & a few other small parts. I have most of the gun, just missing mainly the rec. internal parts. Will parts from a Mossberg 500 work with my gun? Seems like I can find most of them, but not sure if they would fit. It's a decent gun I would just like to get it in good working order. Thanks for the help.
