WTB: 870 12ga for parts/repair

[Screaminta]

I figured I would post here before getting something through gunbroker.

 

I’m looking for an inexpensive/beat up 870 12ga frame that I will use parts for a slug gun build. I need everything minus stock and barrel as I do not want to  switch barrels once I get a good shooting setup. I would prefer 3” gun but not a must have. Also partial to a wing master frame as opposed to an express but again, not a must have. 
 

It’s really just a tinkering project as I mostly use a m/l or my H&r but I want to see what kind of accuracy I can manage with pinning/shimming the barrel (Hastings), stock mods, etc. it may not be worth it in the end but if I can get the parts cheap enough why not!?

 

let me know what you have! Thanks
