This Polycarbonate piston is a extremely high quality piston from VFC and is the very same piston used in their famous and high quality AEGs. Due to the polycarbonate construction of this piston, it is very light which helps keep strain off of the gearbox as well as a reduce the overall strain on the moving parts. The VFC Polycarbonate Piston is a great upgrade for your AEG and will certianly not disappoint.
This is the stock piston in the Echo 1 Platinum edition M4 and many other VFC guns. Unless your running a stock setup and just need a new piston, I would not recommend this. This piston is a little weak for any gun running over 350-360 fps or any gun with a extremely high ROF. I would definitely recommend looking into other upgraded pistons before spending your money on this. Although it is lightweight, the durability is lacking. Within one month my M4 with a 9.6v battery had ripped this to shreds. I went with a upgraded Bravo piston and it had held strong for almost a year now running a 11.1v Li-Po battery. Just spend a few extra dollars and get something that will last, because a stripped piston can easily lead to other broken or stripped teeth on your gear set.
Good for a stock gun without any spring/high speed upgrades
Not suitable for high rate of fire
Not suitable for stronger springs
The last metal tooth has no reinforcement, and I have seen 2 cases where not the tooth, but the metal plate has broke and let the last tooth drop making the last tooth before the piston fires the next plastic tooth. (if that makes sense) Ultimately, this will cause you to strip each and every plastic tooth until the gun will not fire at all.

Im running this in my clear canadian 150 fps with .12 g bb gun and works great. YEAH RIGHT im running this bugger against an m120 firing around 420 fps at 20-23 rps. Works great first impression the plastic looked great, very light weight lighter then my stock ares piston and is somehow more reinforced while being lighter weight. The plastic is SUPER consistent throughout meaning there are no bubbles or any of that jg junk. The price quality ratio is unbeatable a piston of this quality should be around $30+. Now remember shimming is important with all pistons longevity.
Holding on a m120 2000ish rounds later
I will buy again
unbeatable price quality ratio
good side wall reinforcing of piston
Will not fit a Tar 21 stock back square thingy needs slight file
