Any reason why this might be not MA legal?

Not sure if this thing is cool or tactical. Just curious about NFA rules or if an additional grip could be attached legally.

Pretty sure that if you attach a stock to it, that will be classified as a SBR and then NFA rules will be in effect. No stock on it and it's just an accessory for your pistol.

And putting a forward grip on it would make it an AOW.

Something similar. But these guys won't even talk to you without the SBR stamp.

I believe that an additional grip does require a stamp as well. I want to recreate the Hyman Pistols from the 1930's but...
