More than likely the issue with the bottom metal is like putting any other standard 22 in a chassis where you have to use the "bottom metal" (the part that holds the mag). I hope the only thing that might be needed is a little clearance work on the front, but from the look of the placement of the ejection port they might have it back far enough to just drop into an AICS magazine inlet.
I was thinking about the bottom metal issue. Vudoo magazine is well done and thought out. A lot of people will be wanting to make this into a trainer and drop it into an aftermarket stock. The problem with that is, a lot of companies make an aftermarket stock, that takes AICS mags. Their mag is not going to work, It will work in the stocks that take the standard T3 magazine. Any companies make an aftermarket that will still use that T3 mag. I don't think this is going to work in the TAC A1 chassis or the CTR.
