Wow, I remember asking about these like a year ago wondering why nobody made one. That's pretty sweet that someone does, even if it is "matrix" aka rebranded China. The Marushin 1887 used to be the only one on the market, and it's probably impossible to find.
But $80 still isn't bad for a lever action. Even if it doesn't work hopefully it's not too difficult of a fix. I have no idea about gas guns, that's why I ask other people to fix them for me ;D.
Just to follow up on this: I ordered a TT 2-piece MAV (which I was sporting at NL3) - customer service was very nice and professional, and they saved the last MAV they had in stock for me. However... it took them a month to ship after completing the order, which itself took a month due to a credit card issue with their system, and they sent a different pouch than the one I ordered. I got a helluva deal, around $30 which is good enough for the MAV alone, but I would prefer to get gear more quickly.
