This is why I am going KAC. From what I understand, the guns have had the everloving shit run out of them, and they are configured the way they should be, right from the factory. Slap on your optic, light, and muzzle-device that goes with your can, and go. No need to dick with triggers, rails, buffers, 1-piece gas rings, springs, or any other crap.
Just got back from the range with the APC and ACC. Just swapped back in the H2 in the APC per Jack. Thanks Jack. Had steel silhouette's setup at 300 and 500 yards. Zero wind. I never have zero wind.
At 100 yards I had a .2 mil POI shift on the APC to the right when I put the QDC suppressor on. No elevation change at all. Its like my thunderbeast Ultra 7 on my bolt guns, Almost zero POI difference! I am continuously impressed. 300 yards I dialed 1.3 mils on the APC and sent one down range. Hit the steal but dialed back .2 to 1.1 mils. Next ten rounds all close enough to the center. Went straight to 500 and and continued to make hits at 3 mils of elevation.
Next I verified zero on the ACC at 100 and just planned on holding over/not dialing with that. With the H27 reticle, It's pretty simple to just hold over. Continuous hits, over and over again. I had to turn my electronic ears up so I could hear it.
Forgot to shoot another rifle in the truck as I was having too much fun banging steel. Probably had 120 rounds total down range between the two of 175gr FGMM.

Fine. I'll say it. I vote thread sticky.
😀
I would not in any way recommend using the H3 buffer for these as an overall, but some circumstances can be better with more buffer mass. They run better without a can as is with the factory H2 buffer. I have used an H3 buffer in these using the QDC and QDC/CQB cans, while I prefer the suppressed result of the H3 buffer, I can't see this doing anything to really help reliability for instances that aren't suppressed. I have left in the H3 and run them without a can, and they did run, but I'm sure the span of function decreased. You still maintain a wide margin for function with the H2, even with an optional can. If you shoot these suppressed only, the H3 may benefit those users. The older EMC barrels with the smaller gas port combined with the MAMS, H3, and MK316 can shoot really well, soft and flat, but it's really too much of a good thing. Add in lower temperatures, lack of lube, fouling, etc.. expect issues from that.
Thanks for the clarification and info. These are things that need to be on this thread. I was having good results as we had previously spoke, but was curious about temp ranges. I appreciate all the info and advice you have give me over the last few years. I rarely shoot the APC without a can, and that rifle for the most part is dedicated to the CQB suppressor.
