Very durable, suitable for upgrade up to M130 spring; ACTUAL product comes in black
This piston is not compatible with the latest CA M15A4 gearbox.
The use of aftermarket airsoft parts is not an exact science. Some parts may require fitting even thought they were designed to fit without modification. Professional installation of upgrade parts is highly recommended.
I purchased this piston in late 2006. I put it in an ICS AK74, as well as a Systema aluminum piston head and M120 spring. For three years, this was my primary AEG. The only problem I ever encountered was the spring broke. Now, five years later, the piston looks almost like the day I installed it. The only indication of use is the 2nd tooth is a bit worn. As it has been stated before, removal of the 2nd tooth is practically necessary anyway.
Very durable, light weight, long lasting. Works great under _400 FPS conditions. No personal experience with piston in _400 FPS set ups.
As with any piston, you should remove the 2nd tooth to ensure proper gear meshing.

this is a perty good piston my CA CQB seal has this piston in it. I have went through 3500rnds. and the very last tooth before the bigest one has been nocked off. but still works like a charm. I have no clue to why that tooth poped off...
8/10 in my case.

Gaurder pistons are the way to go. I have one installed and it has been pullin an m120 for 7000 shots, altleast. Although, i am getting some wear on the first tooth. The piston I recieved was black, not blue, as in the picture.
