CA Reinforced Piston (Full Metal Teeth)
So I decided I wanted more power in my m16, and I got this piston and a 210% spring, I think the spring isn't much different than my m130, but this piston is built to last! The polycarb piston body supports the steel teeth from underneath, so I don't see cave-ins happening ever. The teeth are very strong, it took me over an hour to file the first tooth and half of the second one for aoe.
-made of very strong material
-metal teeth are super strong
-not a brittle piston, I bent it in a vise and it went right back into shape
-lighter than a full metal piston by a lot, only a little heavier than a poly piston
-price is good, it seems $25 is enough to get you a very good piston these days
-took forever to correct aoe with a hand file, but the strength is a good thing
