I have three competitive shooters among my clientele. All three have and use suppressors. None would stand for less accuracy because of the suppressor (or for any reason). Threading a barrel for a suppressor or break is as critical as cutting the crown, it needs to be exact! When the job is done correctly there is no noticable difference in accuracy. I just finished a nice rifle last week, Defiance "Rebel" action, Broughton barrel, Mc A5 stock, and a "Thunder Beast" 30P-1 suppressor. By the e-mails I've received from my customer he's very happy, and he wants the utmost from his rifles. As for where to buy one, no doubt, that can only happen in your home state, or maybe , shipped in to a class 3 dealer in your home state. I'd almost bet, if you looked around in a 75 mile radius or where you live, you will find a reputable class 3 dealer that can help you. This might not have been the info you were looking for, but, I had to reply to the accuracy statement.
