Hi! I'm looking for tightbores for my GHK ak. I have narrowed down my choice to two options: A prommy 6.03 that is $70 An action army 6.01 that is $24, yet I've heard good things. I'm looking for an FPS boost (both will give me one), accuracy at range, consistency, and viability in a GBBR platform. Will be using maple leaf 70˚ blue. If ya'll think the 6.01 is OK, I'm willing to clean after every game day etc. Its mostly a price issue. Thanks a million!
