I have used these pistons in a lot of my customers guns and the pistons do exactly what they are designed to do. FPS Softair is a trusted manufacturer and I use nothing else now. Read the description and apply the part to intended use.

Garbage
Broke after 300 rounds. Rack of teeth snapped in 3 places! This piston is not strong enough for any medium or high stress build.

Hello, sorry for the issue. We use this piston in our builds without any issue. A high rate of fire can make the sector gear hurt the piston rack gear before it comes back, can you please contact our customer service ? many thanks. regards
