other than external adjustability, is there a difference between a stock a/c 2k reg and an ergo reg?
what's the lowest pressure a stock 2k reg can be set at?
do aftermarket valves only allow for lower running pressures, or are they more efficient as well (more shots per tank fill)?
why does it itch when i touch it?
