Is there a list somewhere of the "standard" gas port sizes on carbine and rifle length gas systems, AR10 and LR-308 would be good, too.
What is the "perfect (M16 length)" gas pressure needed at the port?
Better yet, is there a formula to get the hole size right?
I'm building a wildcat with an extended length tube and hate to do a "Just drill one and try it out, repeat" I'm putting on an adjustable gas system, but want to get the hole close.
I have Quickload and can figure approx. pressures at different locations on the bbl.
Any info would be appreciated.
