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
