Not particularly impressed with that sawed-off Noisy Magnet. Especially since I can almost guarantee it's not NFA, while at the same time being broadcast here on a public gun-related forum.
Maybe it's in Europe. Agent Schmuckatelli, that's my story and I'm sticking to it.
PGO shotguns? Waste of good money. Check in with Dave Mc on THR for the full story on that. It looked good when James Caan used one in El Dorado, and that's about it.
The forum it was on said it was a registered SBR, and the filename itself says "SBR", so I assumed it was safe to post.
Some people have a lot of time and money for tax stamps!
As for PG shotguns? Old-style grip, yes, it's a good way to punch your teeth in. But the COPstock really does work, and makes it absolutely controllable by routing all that recoil into an internal mechanism.
Try one, you'll be amazed.
