Rockinbar sold me my .22 caliber Marauder Pistol with butt stock and it is one of the coolest urban assault carbines you could ever have.
It is not real fast/powerful but that in turn makes it really quiet. It doesn’t have a silencer and it’s still the most quiet air gun we have. Much quieter than a Gamo or similar and you will fall in love with the rotary mags. I have a 3x Leupold on it and it is deadly, deadly, deadly on iguanas.
It’s also very compact which is nice. Especially if you find yourself shooting out of a truck window a lot. Which I do.
It uses a hand pump. I’ve never felt the need to use a tank.
Rockinbar probably has more air gun knowledge than anybody here. Good luck with your search.
Yours has an integral suppressor as well. Sleeved barrel inside the suppressor.
I suspect you may be fairly close to me now. For how long, I don't know, but if you get a day or so off and want to go thermal some hogs and coyotes, let me know.
