PPS-43 Recoil Spring Assembly

The PPS-43 Recoil Spring Assembly is what gives the PPS-43 the ability to eject, chamber, and fire repeatedly. When the bolt fires a round, the recoil forces compress the spring of the recoil assembly, and once the energy of the spring surpasses the recoil pulse it will push the bolt forward to chamber and fire the next round. This process is at the heart of any open-bolt sub-machine gun and makes the recoil spring assembly a critical part for spares to keep your PPS-43 operating correctly for the future.
