These extra-power striker springs make the striker move faster and hit harder to reduce misfires and increases lock time. To the shooter, the faster the firing pin strikes the primer, the tighter the group.
All Springfield actions
Factory spring is 16 pounds.
Extra power striker spring decreases the lock time of the rifle. The lock time is the amount of time from the moment the
striker is released from the sear until the striker hits and ignites the primer. The shorter the lock time, the shorter the time the
rifle has that it can move off of the target.
Installation requires disassembly and reassembly of the rifle's bolt.
