6ARC gas systems and A5 buffer systems and factory ammo...what's the baseline?

[dms416]

While it's not always clear, and port size is always a factor...

Where it seemed like the jumping off point for one's preferences in 5.56 is, it SEEMS like the starting point for the 6ARC is the next step up in gas length AND down one weight in the A5 system.

For example: where I would traditionally run an unsuppressed 18" rifle with an A5h2 in 5.56.... for a 6ARC 18" on a rifle +1 with an A5h1 (or 0) seems a parallel operational envelope.

Am I about in the ballpark?

Ran into an issue with this recently, they make T0 weight buffers which are equivalent to standard T1 buffers at 3.8oz, for the A5 system. Id get one. Wolff also makes as 10% less power rifle length spring. If you're going to be playing with 6arc and A5 systems, Id make sure to get those to increase probability of making it run reliably after mixing and matching.

I'm not sure I'm tracking correctly on what you mean by T0and T1
A5H0 is 3.8oz already
A5H1 is 4.56
A5H2 is 5.33

Yeah, that the A5H0 is equvalent to a std carbine T1 at 3.8oz. So thats probably the best place to start.
