So I recently swapped from my 10.5 supressed setup which was a bcm parts based build I did a while back. The gas was tolerable and using a spikes t3 buffer ejection was great upsupressed and pretty darn good supressed. I switched to 12.5 to gain some velocity and it's still carbine length gas system. I have an adjustable gas block here wondering if you think it's gonna be way way to gassy now with a standard block? Getting out shooting tomorrow just curious if I shiuld swap the adjustable block on it or run it and go from there? New barrel is also a BCM

Your ammunition pressure curve and gas port diameter will dictate that. You won't know until you try.
I run superlative arms adjustable gas blocks on all my rifles. With that and charging handles ment for gas blow back i have little gas in my face. 10.5", 16", 20" i just put together so havent tried yet and a 16" 6.8spc. Keep adjusting till ejection was good for both suppressed and non. Dont forget to clean the gas block out from time to time by running screw in and out several times. Remember how many clicks for your settings cuz i did once lol
