    Okay, so I hear that I must replace my stock King arms hop up if I want my gun to be accurate so I see these two being the likely candidates and I am very open to other suggestions as well, like the pro win one, having an aeg-spec hop up would be very nice and can someone tell me a. which hop up I should choose (drop-in fit only please) and b. if pro win mags are compatible with a plastic g&p bolt?
