"Thanks to its removable return spring in the forearm, you can pull back on the forearm of the Tristar Cobra III Force Pump-Action Shotgun and release, and this spring will return the forearm forward and close the chamber for rapid-firing action. Or remove the spring for traditional pump-shotgun action. This tactical shotgun from Tristar features a receiver-mounted Picatinny rail, another Picatinny rail under the forearm, ghost ring sights, and a synthetic forearm and pistol-grip stock with soft rubber grips for confident handling. The 18.5"" barrel boasts a muzzle brake choke system for significantly reduced recoil. This removable choke system uses BenelliBeretta Mobile threads, 1 extended choke tube (Cyl), choke box, and choke wrench. Swivel studs. Safety at trigger guard.
