Inertia Spring, Factory Benelli M2 or Stoeger 12ga

Now available! This hard-to-find spring is essential to the function of your inertia-operated shotgun. We have available both the original Turkish-made Stoeger M3000/M3k/M3500 spring, and the Italian-made Benelli spring used in the M1/M2/SBE/Montefeltro series as an upgrade. Please select your choice from the drop-down menu. This is an absolute necessity for your emergency parts kit, and should also be replaced approximately every 10,000 rounds.
