You will have to ask themselves. I don't believe it's a set standard.
When I had my 5 done, I remember going around to them, whoever Cherokee Gun n Pawn recommended and FTA and GFL was the cheapest and quickest. Mine got done the same day.
Looking for some recommendations on which suppressor to purchase. These current wait time have me thinking it's time to get one.
I have no clue about suppressors.
What I want if possible...
A suppressor that will work well with standard M193 ( I know it's not Sub's.)
Work well on...
