I got my 18.5" barrel today, looks good, no choke.
The folding stock works well, and really cheap, and is is 2.5" shorter than the fixed stock. I taped a 4" section of pool noodle around the thin bit, so now it is snug, and still folds.
The "Magazine Factory 5 round for DA Grizzly-Mag Shotgun" actually chambered a round with 5 loaded, without major modification! This is a first.
Edit:
"Magazine aftermarket 5 round for DA- Grizzly-Mag shotgun" was the one that didn't feed, so perhaps there is a difference.
