Extreme-Flow Valve Assembly Spring to be used with heavier hammer and custom sturdier one-piece valves only.
Kindly do not use these springs with the factory valves as they would not stand the beating from these springs.
Upgrading to this spring, you would also have to upgrade your breech knobs to sturdier ones as these springs causes the factory breech to bend over a period of frequent use.
This Spring replaces the factory main hammer spring
