I am new to the FX Impact world, I have the .22 Sniper M3, very accurate at 150/70 (first/second) reg. I just bought a 600MM .177 Barrel and am trying to create a near silent 12/FPE backyard 10-20 yard tune. Would like to understand the settings for the first reg, second reg, valve adjuster, macro, and micro adjusters. Has anyone had experience with that? Can I drop the second reg to 50 bar or should I turn it up and try to adjust the hammer to take small sips of air? Please let me know if anyone has any ideas…. Usually shoot JSB 8.4 or 10.3. Thank you in advance….

Your main enemy is the plenum size! sub 12 IMPACTS usually run at 50-60 bar reg, the bottle reg can stay as the factory setting.
Sub 12 IMPACTS come with the original very small plenum to keep them consistent, the easy fix is a plenum plug to reduce the plenum volume but of course it requires complete dissasembly of the gun but will transform its consistency in sub 12.
You will however still hear the internals of the gun as a sub 12 is indeed almost silent, check out the sub12iargunners channel to see what they do.

Thank you…. Adding a plenum plug is not an option, as I want to use the gun for multiple tunes across several different calibers. I will try reducing the second Reg to 50-60 and see how low I can tune with accuracy…. Thanks again, I will share my tune once completed….

Very easy! Set regs to 170/150, back the preload all the way out and crank down the valve till you reach 12FPE. It will be stupid quiet.
my crown MK2 shoots at 8 FPE with reg at 150 without the ability to crank down the valve.
