I have to update this:
I ordered one of the Scorpion PA-01 shotguns. It arrived, but it wasn't what I expected. So I took advantage of Wanstall's great return policy. I expected a 'Remington action', but it wasn't exactly a Remington action. You couldn't replace the bolt carrier or forend - they're not the same. In fact, there isn't even a forend tube - it's one molded piece of plastic that runs along the magazine, rather than a plastic forend around a forend tube. So forget any aftermarket Remington stock / forend on the thing, it can't happen. A Remington bolt won't fit into the receiver, and a Remington 870 forend tube won't carry the bolt regardless.
It's too bad - I had a Boyd's wood laminate pepper stock and forend for a Remington 870 that I wanted to put on it. With the finish of that shotgun it would have perfectly matched a Ruger Gunsite Scout.
Anyways... The good part of the review here is that the service from Wanstalls' was awesome. Their satisfaction guarantee on their webpage is rock solid, I have done business with Wanstalls' twice before this transaction, and with their help returning the item, I'll definitely continue to do business with them. Highly recommended.

Yep. That's piece of mind.
