Introducing the most advanced break barrel system in the marketplace, engineered and produced by SIG in Newington, New Hampshire. The common misconception among many is that high muzzle velocity makes for a better air rifle. In actuality, foot-pound muzzle energy is a more accurate gauge of the power of air rifles than the speed at which a projectile comes out of the barrel. Down-range accuracy and retained energy are better with a heavier projectile leaving the barrel at subsonic speed rather than an impractically-lightweight projectile leaving the barrel at a supersonic speed of 1400+ feet per second. This .177CAL suppressed single-shot, Advanced Sport Pellet (ASP) air rifle delivers down-range power and accuracy with the lightest cocking effort in its class, making it ideal for hunting small to medium game.
