Add a suppressor and a Form 1 M203 40mm DD....you just never know when you can acquire some and indirect fire is FUN.
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.
