Hi folks,
I picked up a police trade in 18" 870 Magnum, serial starts with W, so I assume Wingmaster. Seems to date from 1980's with H stamped on barrel and inside receiver.
Anyway, outside of some scratches to to the blue finish and wear on the action bars, the gun is great shape. Cycles smoothly and looked good internally when torn down for cleaning. I could use some advice on the few things I did notice:
When the gun is racked for dry fire, the bolt backs off the barrel a hair so that the bolt jumps when the trigger is pulled. Light forward pressure on the forearm when doing the same reduces the bolt movement when fired, but does not eliminate it. I have a Express Magnum and Police Magnum both purchased new and they show zero bolt movement when dry fired.
So my questions are:
- Is this a problem that requires parts replacement?
- What parts hold the bolt firmly forward when racked (actions bars or something inside the receiver)?
Thanks in advance for any help. I have searched the site for a while, but find precious little about 870 problems...
