Brownells 75th Anniversary - A Shooting Heritage

Converts Your Field Gun To A Tactical Workhorse

High quality, OEM components allow you to easily transform your Mossberg 500 into a reliable, high-capacity, self defense weapon. 20" long barrel chambered for 2¾" and 3" magnum 12 gauge loads features a fixed cylinder choke for maximum pattern coverage at combat ranges. White bead front with adjustable, U-notch rear sight helps provide rifle-like accuracy when shooting slugs at longer distances. Magazine extension threads solidly into the receiver to provide 8-rounds of firepower; knurled takedown screw retains the tube in the magazine support on the barrel to eliminate the need for a separate barrel clamp. Includes extended-length magazine spring for reliable feeding.
