I have the FA 22 LR mini-revo. I paid 150 1-1/2 eons ago so 200 for a Mag version sounds ok. I shot one of my chronys with this gun. It is a solid gun, but don't ever pop the sideplate off or you'll beee sorrry.
The FA mini-revo were the first mini-revo's. The two guys split partnership and the other went on to make the NAA mini-revos. The FA does not have the notches between the chambers so my 5 shot is carried 4 up. I'm not sure about the Mag versions. I expect that they're the same way.
I did own a NAA 22 Mag once and I can not tell any difference in quality to the FA. They're good little guns.
