In order to celebrate its 100th anniversary, Mossberg has launched a variety of new firearms, one of which is the "retrograde" pump-action shotgun. The "Retrograde" series is divided into 500 and 590A1. They are also 12 gauge (18.4mm). They use a classic traditional structure, equipped with a buttstock made of walnut and a round slotted handguard, but the interior is completely modern. Mossberg's excellent quality and unquestionable reliability have made these two shotguns a very good sales performance. This article is a review written by Bill Battles, I translated it for you to share.
First introduce the more concise "reverse" 500 shotgun. The barrel of the standard wall thickness is 18.5 inches (470mm), equipped with a fixed shrinkage and a 3-inch (76mm) barrel. There is a brass beaded front sight above the muzzle, and there is no rear sight. The walnut handguard and butt stock are darker in color, and there are anti-slip lines on both sides of the grip. The perforated rubber butt bottom plate is very thick, and there is a black plastic gasket about 6mm thick between the wooden butt. The receiver has a threaded hole to install a scope. The front part of the cylindrical magazine and the lower part of the butt have a rotatable back strap loop. The safety is located on the top of the receiver, which is convenient for thumb operation.
Mossberg 500 "Retro" has a total length of 1003mm, an empty gun with a heavy ammunition capacity of 6+1 rounds, and an empty gun with a weight of 3.06 kg. There is also an optional configuration for shooting 70mm long shotguns and 5+1 rounds magazine, which is the same as other 500 shotguns. All the metal parts are coated with blue, plus the wooden buttstock and handguard, it has become a clear stream in the shotgun market filled with black polymer accessories and tactical styles, attracting the attention of many gun fans. The suggested retail price of the Mossberg 500 "Retrograde" is US$519, or approximately RMB 3,663.
In contrast, Mossberg 590A1 "Retrograde" is a standard defensive shotgun, which is more tactical and functional than Mossberg 500. The promotion. There is a threaded hole on the top of the receiver to install a sight. The handguard release lever is on the left side of the bottom of the receiver, just behind the trigger guard. A variety of models of Mossberg 590A1 shotguns have become the first choice shotguns for military and law enforcement agencies around the world. It is the only pump-action shotgun that passes the Mil-Spec 3443E standard. From this perspective, it can be known that it can fully meet the needs of ordinary users. .
Mossberg 590A1 "retrograde" is equipped with a 20-inch (508mm) thick-walled barrel, with a heat shield above the barrel and a 3-inch cartridge. The sloping front sight is inlaid with orange polymer and matched with the "ghost ring" rear sight with adjustable height and wind deviation. Wings are provided on both sides of the rear sight to prevent bumping. Mossberg 590A1 has a capacity of 8+1 rounds (7+1 rounds when loaded with 76mm ammunition). The metal parts are Parkerized to provide the ultimate anti-corrosion ability. The front part of the cylindrical magazine has a bayonet seat, which can be installed with a bayonet. The suggested retail price of this shotgun is 930 US dollars, or about 6564 yuan.
The two shotguns have obvious differences in the barrel, and the internal parts are also different in the surface treatment process. The steel trigger is a standard model 590, which is inexpensive and has excellent performance. The trigger stroke is about 6mm, the trigger force is about 31 N, the running is smooth, and the firing is simple.
Mossberg 590A1 "retrograde" when the bayonet is installed. Since the bayonet ring is fixed in front of the tubular magazine, the gun strap needs to be removed first, otherwise it cannot be installed. This shotgun is equipped with a bayonet, which is very deterrent. Since the ring of the US Army bayonet is the same as that of the card, the 590A1 "retrograde" can be equipped with various types of bayonet. Mossberg 590A1 "retrograde" has a total length of 1041mm and an empty gun weighs 3.18 kg.
You can see the difference between the two front sights. The 590A1 (above) uses a higher front sight, and the inlaid orange material is convenient for aiming. The bead-shaped sight used in the 500 (below) is a traditional shotgun setting, which is convenient for quick and probabilistic aiming, while avoidingHook. From this photo, you can also see the difference between the barrel surface treatment and outer diameter of the two shotguns.
The butt parts of the two shotguns are exactly the same. This perforated butt bottom plate improves the flexibility and reduces the perceived recoil. From an aesthetic point of view, walnut wood is far better than polymer materials. Because of the micro-pores on the surface, it can absorb sweat from the palms and avoid excessive slippage.
The accuracy test distance is 15 yards (13.7 meters), using Hornady 70mm critical defense (Critical Defense) 00 deer bullets, the 500 is scattered higher than the aiming point 120mm, and the 590A1 is higher than 165mm. Since the 590A1 is equipped with an adjustable rear sight, it can easily adjust the aiming point, which is a feature that the 500 does not have. In the test, both shotguns showed excellent reliability without any failure. The handguard of the 590A1 operates more smoothly. Of course, both shotguns are in the running-in phase.
Mossberg shotgun has many styles to choose from. The same is true for these two "retrograde" series. Users can choose different configurations according to their needs. For example, installing a 590A1 sight on the 500 is no problem at all.
Mention the shotgun, many people will first think of the Remington 870 series, and the Mossberg 500 series is better than the former in some aspects, but it is less well-known.
