Question for anyone still following this thread here....
If I can only do a direct exchange for my barrel and bolt and end up replacing it with the exact same thing.. then whats my next step to prevent the problem if it's based off the cyclic action being too fast and harsh for running suppressed? Since the factory ammo and my handloads are running same speeds and factory stuff shows a lot of high pressure signs, do I need to change buffer weights / springs to try to control the harshness of the cycling to eliminate the issue of breaking bolts? From what KLEM, LRRPF52, GRAYFOX and others have chimed in on here I seem to have an issue where (even the factory ammo) is too fast for my rifle setup and causing issues. I haven't pulled the barrel yet since I've been so busy with work and all, but if I can only do a direct exchange for the same setup (satern type II, bolt head, Mid Gas, etc) then won't I still have the same issues down the line unless I address how hard the gun is cycling? Taking handloads out of the equation... Factory ammo was averaging within just a few fps of my handloads but had ejector marks on every piece of brass, high SDs, a large ES, and erratic ejection patterns. Even if I get exchanged out and run same setup and only run factory ammo won't I have the same issues? Do I need to get a heavier buffer and then retune my gas system? Ideally I am going to try to exchange it for a 20" with rifle length gas and go from there, but if that isn't an option, what do I need to look into changing?
