SRD22X for sale. Minimally used. This will require filing with the ATF for this transaction and will include a $200 tax stamp on the buyers part. 

You pay the buyer (me) the sale price and fill out the forms which I sign, you mail that to the ATF, and then the ATF sends me notification when it is approved and I transfer the suppressor to you. You'll have to look up the process with the forms.
