Adjustable AR buffer not sufficient: Help
I'm running a DD 11.5" bbl, BCM BCG, Vltor A5 buffer system. UNSUPPRESSED, it runs fine with Sprinco Green spring & either A5H3/A5H4.
Note: AMMO-all shooting done with M193. It functions flawlessly either suppressed or not, and is a fine, soft shooter.
SUPPRESSED with an AAC-556-SD can, it acts over-gassed: ejects to 1:00.
Got a HeavyBuffer A5 buffer tungsten weight kit, built a 10.2 oz. buffer, coupled with a Wolff spring...ejects to 2:30-3:00. I just can't get it to 4:00-4:30.
I do not want to install or rely on an AdjGB.
What the heck am I doing wrong?

Agreed with all of the above, I really never pay attention to ejection unless it’s dribbling out. That said, running a green spring with an A5H4 unsuppressed is a bit surprising for a barrel that is supposedly well gassed, especially if it’s a weaker variant of 193 or more appropriately, weak 55gr.
When was the barrel made? Their MK18 barrels used to be significantly over gassed, not sure if 11.5s were as well.
