This new Mossberg 500 Persuader shotgun fires the 12 gauge shell. It has an 18.5" barrel with an overall black finish. Mossberg installed a Matthews Harmonic Damper in the stock. This device dampens the vibration in the stock after the round has been fired thus dampening perceived recoil. It is essentially a dumpbell shaped weight enclosed in a rubber. The weight can bounce around soaking up vibration. This shotgun has a factory installed door breaching end and a forearm loop. It comes with box, manual, and a lock. This Mossberg shotgun holds 6 rounds.
