One of my newly threaded rifles causes strikes to the baffles of my suppressor, and I need some input.
I sent two Cooper model 52 rifles to Cooper to be threaded for a suppressor. Before I sent Rifle #1, I included specifications for the suppressor I planned to use (a Saker). After having Rifle #1 threaded, I told Cooper I wanted to send Rifle #2 "for the same treatment as the other one" but I mentioned I was planning now to use a different suppressor (Thunder Beast which I specified). I also mentioned that I would be using an Area 419 adapter (which I specified) for the appropriate shoulder for the TBAC can. Cooper did not ask for any additional information (including any different thread specs), but at the suggestion of the Cooper gunsmith, I did agree on a different pitch for Rifle #2 (9/16) vs. Rifle #1 (5/8) due to the barrel width. There was no other discussion about any variations in threading.
Rifle #1 seems to work fine with the TBAC and the adapter. Rifle #2, however, strikes the baffles. TBAC says the problem is that there was no recess cut into the barrel below the threads, as per the Can #1 specs (and as apparently was done on Rifle #1). TBAC said that the absence of a recess is the problem - which they have agreed to fix for a reasonable sum.
Did I do something wrong, and do I have unrealistic expectations here? I communicated in advance with the rifle company, adapter company and can company and thought having the rifle company do the threading made the most sense. We all seemed to be on the same page. After figuring out the problem, Cooper, however, just told me they decided to not cut a recess in Rifle #2 (as it would be "too thin" there and that would "cause accuracy issues"), but they never communicated this decision with me, or told me about the accuracy concerns. (If they had done so, I might have chosen not to thread that rifle.) Is this my fault? I guess I could have been proactive and sent the thread specifications for TBAC to be used on Rifle #2, but TBAC said that the specs are the same (both include a recess).
Cooper has been very responsive and pleasant, and has stepped up to pay for some shipping. But they are saying the baffle strikes (and resulting damage to Can #2) are not due to their work. I've asked several times for an explanation as to why they (apparently unilaterally) decided not to cut the recess and why they did not discuss that with me. I am still waiting on an answer.
