"A lot of people say a spring is a spring but when it comes to this one. The Prometheus spring has been the most reliable spring that I have ever used. I used it in all my airsoft guns. I highly recommend getting this you won’t be disappointed

"Good spring, identical to the systema. May want to save a few bucks and go with the systema instead. Also the paint tends to flake off after awhile.
