An acquaintance of mine is having an issue with a 6.8 that has a smaller gas port than his other rifles. He's developed handloads for these rifles and he can't make his new rifle function with his current handloads. He's confirmed it's undergassed by re-checking gas block alignment, switched lowers, and switched BCG's. He is definitely short stroking.
On my 5.56 carbines I'd just switch to more powerful ammo or reduce buffer weight. In his situation he doesn't want to mess with his handloads, so ammo is out. He has an A2 stock and rifle buffer system, so moving to a lighter buffer is out unless he wants to buy a JP low mass buffer for big $$. He could open up the gas port but I think it's melonited which would make it tough to drill. Would a reduced power spring work?
Any ideas?
