Photos are representative, but buyer will receive a virtually identical specimen from the same shipment. Here is Mossberg’s best all around semi auto shotgun, equipped with a Choate steel magazine extension for overwhelming firepower. Shotgun Manufacturer and warrantor is O.F. Mossberg & Sons of New Haven, CT. Extension tube kit manufacturer is Choate Machine Tool of Arkansas. This shotgun closely corresponds to current production Mossberg 85122, except this one's tube is recessed 1/2 inch behind the barrel's muzzle. With the Choate Tube, it strikes a happy medium between the Mossberg 85177 Flanigan Rhythm variant, and the JM Pro 85133.Construction is steel barrel, bolt, magazine tube, trigger, and internal parts, in a light weight alloy receiver with polymer safety button and trigger housing. Type is dual system self regulating gas operated semi-automatic. Chambering is for 12 gauge shells, 2 3/4 inch and 3 inch magnums interchangeably. Magazine extension tube is steel production by Choate Machine & Tool of Arkansas. Its capacity is 9 rounds of 2 3/4 inch; or 8 rounds of 3 inch shells. Fully loaded capacity, then, is 9 + 1 on 2 3/4 inch. With #4 Buck, for instance, it can deliver a similar number of projectiles to an entire brick of .22 ammunition, in fewer than 5 seconds. Adept operators, we are told, can leave a round resting on the shell carrier for even more capacity. Barrel is 26 inch, Mossberg Accu-Choke ®, same thread as older Winchoke and old model Browning Invectors. Since the 930 is not back bored, it will handle rifled slugs and sabots just fine. This shotgun comes with a .712 vicinity modified tube, and Accu-choke tubes are readily available throughout the country. Sight System is 11 Post .375 wide serrated top Ventilated Rib, with Red Fiber Optic front sight. Receiver on the 930 is contoured like the Model 500 and 835 shotguns, for a Weaver #88 or 417 four screw base. Safety is classic Mossberg top tang style; and the .250 smooth face blue steel trigger pulls at 5 pound vicinity with minimal felt creep. Length of pull is 14 inches from the trigger face to the end of the 7/8 inch black factory recoil pad. Swivel studs are Choate Permanent Swivel Clamp forward, and stock integral rear eyelet. The Clamp helps prevent damage to the magazine tube proper if the extension encounters direct stress. Weight empty is 8 pounds 2 ounces, with center of gravity at the operating handle. Overall length is 47 inches. Stock and forend are pliable, recoil absorbent black graphite based synthetic. Buttstock drops 1 1/2 inches at the comb, and 2 1/2 at the heel, with a 3/4 inch right hand cant. Metal finish is matte blue steel, with matching black matte anodized receiver, and black trigger group, stock, and forend. This 930 and its mates come to us from Mossberg’s distribution system.
