The Grendel and its variations

[Mutt]

The "MAIN" legitimate reason is ........ MONEY. They can call thier version the "Improved Custom Model" and charge more for it. Where it works better or not. The whole thing p@#$$ me off because you end up with all this other crap floating around in the market. And, everybody just ends up calling them a Grendel. That's why I tell people to buy a Grendel that actaully has the name stamped on the barrel. Chances are those are made to the Grendel chamber or they would be stamped with some other nonesense.
