i have been reading so many threads over the last few day and i cannot remember where i saw this at.

can you tune with heavier buffers a 10.5" carbine gas system to feel like a mid length gas system? i think i saw somewhere people were saying they were using h3 and h4? this will not be suppressed at this time for what i want to do. if adding the heavier buffers to soften the recoil, will that have the potential to run into problems that i am reading with the mid length gas systems with weak ammo?

set up is DDMK18 shooting out to 300yds.
