I got my replacement top cap, o-rings, and the new spring post assembly. As far as I can tell, the bore in the top cap for the drip tip is now the PERFECT size, and the tolerances of the ID are actually slightly tighter so it sits more firmly on the top plate. Good job Rip, you made good on your promise to improve the AC9, and now it's about as perfect as I could have hoped for it to be. I'll be doing an updated review of the atty in the next few days, and JC West and I might actually be doing it together!


Now that's an air hole
