After a good amount of experimentation, you'll figure out that short stroking the bolt will produce a flatter shooting gun and if you want to take advantage of that to its fullest potential, then you'll disable your LRBHO. I've got mine setup with a Blitzkrieg Hydraulic buffer, Sprinco white spring, and 9 or so quarters stacked on top of a H11 wavespring plus one more quarter between the top of the wavespring and the buffer. You'll have to play around with springs and shims (quarters) to fine tune everything. Type of ammo, type of BCG, type of barrel, type of spring, type of wave spring, and preferred recoil impulse are all things you can change.
Soon you'll figure out that there's no perfect combination
