Anyone put a choke in a grizzly barrel 12.5"

Sounds good. You're better off with a pedestal on that short barrel anyways.

I knew this in advance, I asked Casey to do it and he mentioned he would have had to anyhow.

I've got .875 OD at muzzle. Brand new just out of the box bead sight, sling stud on end cap.

I'd say you might be OK, but I would ask before shipping it if you want Remchoke. 100% viable at .890", less than that, better to ask a shotgun smith who has done a lot of choke installation.

.875 would DEFINITELY take invector chokes, but Remchokes are a little bigger diameter.
