Looking for insight as to what users of this specific barrel and using a suppressor are using as far as buffer systems. This barrel has a small diameter gas port from what I understand but I never measured mine.

I use the 12.5" BA hanson barrel with the supplied gas block and a saker 7.62 on the end. I am currently using an H3 buffer and a red spring with the suppressor on. To get it to run unsuppressed (very rare) I pull that setup and put in the regular carbine buffer and blue spring. The rifle still seems a little overgassed when suppressed, guess the saker produces a lot of back pressure.

I am wondering if there is an A5 setup I could go to that might perform well suppressed but still let the rifle function with the can off. Anybody have any insight? Not interested in adjustable gas blocks, my other suppressed guns run beautifully without them. I MAY look into a gemtech or bootleg carrier. The grendel barrel is a little different due to small gas port so im trying to find that sweet spot.

The rifle is 100% functional right now, so no complaints. Just curious if there are some other setups I could try.

And just fyi...if anybody is thinking about buying one of these barrels, I just got back from the range this morning. consistent hits at 850 with factory SST, could not connect at 950 but I ran out of holdovers on my TA31F . The wolf ammo with same zero was consistent at 550, with about 50% hits at 650. My buddy had his 5.56 and a .308 GAP rifle. He was fighting a very inconsistent wind all morning, I did not have to hold for wind hardly at all. .5-1moa at most when at the 850 target.
