The Rattler 357 is a 15 shot semi-automatic big bore air rifle purposely built for larger game as well as long range shooting. With these 15 full power shots, the rifle can produce upwards of 270 ft-lbs of energy with each pull of the trigger. Made with the highest quality components and engineered to withstand the taxing demands required by the .357, the Rattler can stand up to the toughest shooting conditions. The long list of features include a 580 cc air cylinder, an adjustable regulator, and a hammerless firing system uniquely configured for incredible shot-to-shot consistency. A knurled throttle knob lies just below the high capacity magazine for quick and easy velocity changes and a wide range of power adjustments. Reaching maximum power of 270 ft-lbs, the Rattler is as comfortable shooting 81 grain pellets as it is sending 174 grain slugs down range. The Hammer Forged Nitrate Coated TJ barrel provides unmatched accuracy, producing sub MOA groups at 100 yards. At 21mm, the fixed Titanium magazine has enough depth to accept some of the longest slugs on the market today. The Western Rattler 357 is also equipped with a 20 MOA Picatinny scope rail, dual side rails, and a Picatinny bottom rail for attaching the bipod or accessory of your choice. A solid aluminum shroud silencing system quiets the report to a very comfortable crack.
