Hey,

I have never heard of Military Action. They have a double notched 6.03mm 590mm barrel for 50$. Anyone have any experience with these tightbores? Would this also be a substantial improvement over a stock barrel? I am running a scs and systema rubber on a stock barrel and not getting the performance I like. Gearbox is stock and compression is good.

anyone?
