this piston is by far the best i have ever had is withstands the hardest setups i have put on it. it had withstood over 100,000 rounds in a 450 fps, 30 rps setup, and only broke when i changed the setup and in less then 1 minute slaped together a shoddy example of a gearbox to test a new ratio and it blew the back clean off. this was however entirly because of the angle of engagment was wrong it was completely off and so put far more tention on the piston then any in existence could handle.
i am using an m130 spring, so i know this piston can handle high power.
word of advice do not modify this piston in any way it will sacrefice all of its strength and integrity.
easy to install
allready has the second to last tooth taken out
mmakes for perfect aoe
this is the perfect piston for any and all set ups and its cheap
and light weight
i keep three on hand at all times
