Back story:
I just had a couple muzzle breaks installed on my MK116 Mod1 and a BCM upper so that I can run my Saker 556. This was done by a reputable gunsmith and he said that as long as the barrel is made by a quality US manufacture that I'm good to go and that I don't really have to worry about the threads being concentric to the bore "especially on an AR, if it was an AK we'd have problems". After the brakes were installed I did a quick inspection by mounting the cans to the PWS and BCM uppers and looked down the breach to see if there was a detectable misalignment. I didn't see any, so I trusted my gunsmith and proceeded with shooting my rifles suppressed at a night match.
The questions below were developed after the inspection of my can following shooting my Mk116 at the night match and testing out my BCM. Upon close inspection I think that there may be a very light baffle strike which now has meme paranoid after I started researching it more.
Upon further research it would seem that just because the barrel is from a "quality" manufacture doesn't mean that the threads are going to be concentric.
Questions:
1st: Are the threads concentric to the bore on a PWS? What about BCM? For those who shoot suppressed, what has been your experience regarding the threads being concentric [or not[]?
2nd: If the threads are not concentric on the PWS, how do I reconcile this? I don't want to void my warranty.
The BCM barrel I can easily have removed and sent to ADCO or someone like them. However with the PWS, because of it proprietary system I cannot get replacement barrels and I'm pretty sure that I'd void my warranty.
3rd: What has been your guy's experience shooting the PWS system suppressed, if you have input/ experiences of PWS vs DI suppressed that would be greatly appreciated?
Since I've already shot the PWS with the can on it, I noticed that I was getting a lot of gas to the face. This with mild 223 loads on gas setting 3. Setting 4 was barely spitting the brass out. I thought piston systems were supposed to be better than DI for suppressed use? When briefly trying out the BCM, I didn't really notice much difference between the piston system of the PWS and the DI system of the BCM. Maybe I just need to try it more, but if anyone has any input that would be greatly appreciated because I'm thinking of dropping my PWS setup for BCM. If I can't detect any real difference, then I'd rather go with something that has more standardized parts, is more affordable, easier to work on/ customize, plus BCM enhanced lightweight barrel with KMR rail is A LOT lighter than my PWS setup with the same equipment on it.
The post ended up being much longer than I had intended, but any input regarding the questions/ topics above would be greatly appreciated. Thanks!
