After working with a spring manufacturer for many months, our new flatwire recoil spring is ready to go!  Wound from 17-7 stainless steel and cryo treated to increase uniformity and life, these springs will outlast your ammunition budget.  With an estimated lifespan of over 300,000 rounds, you'll run the rifling out of your barrel before you kill this spring.
