"this is my favorite piston to use. very strong material with pickup tooth support on the back. angle of engagement is super easy with this, no need to file or dremel down teeth.

"I heard some bad review of the earlier batch of this piston but none the less gave this piston a try. So far so good in my Krytac Gate Titan Krytac Spr build. It's the only piston I tried that is a direct drop in after market piston for a Krytac gear box. The omitted last tooth and shaved second to last tooth makes it hassle free for AOE correction. I've tried SHS swiss cheesed, Lonex red, and Kratos but most of them seem fits too tightly on the rails or the rack is too low and cause excess drag on the sector gears for a krytac. After around 30k round I disassembled the gear box and the piston still seems fine. I did ran into PME twice during that period and broke two bevel gears. However the piston seemed to have survived the incidents despite it being full stroke. Make sure to glue the rack to reduce chance of failure and short stroke the sector gear for RPS higher than 25 on M115 spring.

Build: Krytac SPR 400fps Gate titan with M115 spring full stroke (probably should have short stroked 1 teeth). Have put ASG 22k, 30k, 40K, Tienly 30K, Action Army 30K in the gun. Anything more than 30K ran into PME in full auto and got the motor hot very quickly so I settled for 30K and 22K motors.
