So I wanted to increase the magazine capacity of my M2 20 ga SBS.  Extension tubes for 20 aren't just falling off the trees, and low-capacity 20 ga extensions seem to be unobtanium.

But I did find this Nordic +7 extension; think it's too much?

Looks like a Chiappa Rhino had sex with a shotgun

Too much? Naw, that thing is just a hacksaw away from being just right

reasonably certain this is a joke post... hoping anyway. I shot 3 gun for years, so I'm up on the longer tube than barrel situation. the point of an SBS is to be shorter/lighter/faster than it's full size brethren, so if you want to do that at least put a longer barrel on there to be within a few inches of the tube ending.

short barrels with long tubes get dirty as shit from powder, too, so be ready for that.

OK, ok.  Just a joke.

This is more like it.

+1, but I'm thinking I can cut thre spring a few more coils and get +2.  I'm about a centimeter short of room to fit a 5th 2.75" shell in the tube.

Right now it's 4+1 for both 2.75" or 3" shells.
