"I wanted this Piston to be Great I really did, but sadly today is not the day for wishful thinking. Unlike other Action Army products The AA Piston falls short with only 1 major flaw dragging it down.

Let me start with everything else first. The design of the piston is great! The material they use is strong and the molding has like zero flaws on it. Molding its self of the piston is very nice and looks amazing! The Diameter of the Hole of the piston where the spring sits is wide enough for ball bearings to spin freely (you dont know how crazy hard it is to find a good piston that allows this). Every thing was great, until i put in my gearbox with a sector gear. when Sector pulls back the piston right in the middle of the rack the motion becomes very stiff like the gears are getting stuck some how. Come to realize that the spacing where the Nylon teeth meet the Metal teeth are not perfectly measured or symmetrical with the spacing of the rest of the teeth, metal or nylon. So what happens is that the Sector Gears teeth do not line up correctly with the tooth that meets first contact with the metal piston tooth allowing the teeth to not MESH correctly and causes a slight jamming effect which would be very bad for your electronics/switch/Motor and could cause lock ups in your GB for sure.

So im upset that this piston would not live up the the reputation of AA. This could be fixed but that requires shaving off plastic and possibly metal for this to work propper to allow the Metal teeth rack to sit closer to the Plastic teeth. But who wants to do that when other great pistons are available. LONEX is my goto before and is still now.
