Anyone have a stock off an 880 or 440? I may need to buy one but will also need a measurement prior to doing so to confirm something. Thanks!

Actually, Mike if you can measure the width of your shadow's breech block that would be great. I'm trying to see if the plastic shrouded breech blocks are the same width as the steel ones for a stock swap with this one Gamo I've got here...

I'll check and let you know, in a little bit.
