I bought (2) suppressors on July 1st from Bo Barrows and mailed the forms off on July 5th. They called today and one of my stamps is back. Right at 4 1/2 months. Am I special or what ?
Go with #3 . Then get an adapter to shoot 22lr in your AR. It is super quiet(well mine is) with the 22lr and with the 556 it brings it down to regular 22lr levels. Sort of a combo deal.
