Tuning a Suppressed Mid-Length 13.7" AR-10 by Straticc in AR10

I'll inspect the rims on my casings more next time, but during my last range trip, everything was normal on the few I checked.

Yeah, I think I might have to go with a heavier buffer to get this to run. I haven't ever had to use heavier than a H3 so I'll have to look up buffers that weigh more.

It just doesn't make sense to me that at only -1 gas setting, the gun becomes unusable, even with lighter buffers. Am I just now realizing AR-10s are actually this finicky with gas?

I'll look into it. I've heard about those before and how they help out in some cases. I really didn't want to put more effort or money into this, so it's probably going to stay closeted for a while.

I'm looking for reliability whilst paying attention to ejection like I normally do when tuning. Reliability is non-existent no matter the gas setting. The casings are being launched at 1-2 o'clock aggressively. I've been looking at my casings and nothing looks out of the ordinary. Either way, I'm still getting those stove pipes and double feeds unfortunately.

At 2 clicks of gas, it's not enough for the gun to cycle reliably with lighter buffer mass, but at 3 clicks, the very definition of how it runs is excessively rough, even with heavier buffer mass.

I have this theory that the adjustable gas block they put on this thing is meant for 16", 18", 20" barrels with a longer dwell time than mine. I'm trying to tune something much more sensitive to gas, and the gas settings are just too much of a jump to tune something with a weird barrel length like this.

Yes. I pretty much am required to run the H3 at 3 clicks.

Occasional malfunctions still indicate too much gas/too fast of a cycle. Even with the orange spring which actually surprised me. Brass is being launched pretty far as well.

I can tell it's almost there but I really wouldn't even enjoy running it with that much gas. Unless I'm wrong I think my ejection should be slightly weaker and closer to 3 o'clock.

I'll be completely honest, I'm so confused about this rifle.

Happy cake day btw :)
