The Remington Model 522 Viper is a semi-automatic rifle chambered for the .22 Long Rifle cartridge. The Viper uses mostly polymer in construction; only the barrel, bolt and a few small parts are steel.
The stock is made of Rynite.[4] Barrel length is 20 inches and weight is 4.5 pounds. The rifle has an integral scope mount rail. The polymer receiver is permanently attached to the barrel and the sights are attached to the barrel by machine screws. Magazine capacity is 10 rounds. Remington briefly produced 25 round magazines for the Viper, but the rifle's introduction was only months before the 1994 Federal Assault Weapons Ban, and the model 522 was dropped before the ban sunset in 2004. The stock did not include provision for sling mounts; these had to be added by the owner or a gunsmith.
The rifle features both a magazine disconnect safety and a manual safety, as well as a last-round hold-open.[1]
Official capacity is 11 rounds ("includes 1 in chamber").[5] This requires chambering a round through the port and then inserting the magazine loaded with 10 rounds.
