Maybe the suppressor.
I have an unfilled Form 1 around somewhere, but haven’t decided on the .22 or 5.56model.
The M203 is useless without an HEDP round, and each of those require a Form 1 tax stamp, if you could ever find them.
Thank you for another illustration that the unconstitutional National Firearms Act, and the bureaucracy it enables, must be abolished.
Well...after the balloon goes up, you can get your own ;)
Go with the 5.56 ... it will suppress the .22lr too.
