The Umarex® Syrix Air Rifle uses a Turbo Nitrogen Technology (TNT) piston to propel .177 alloy pellets up to 490 fps. TNT also provides smooth and consistent cocking with minimum effort. This pellet gun comes equipped with a 4x32mm scope for precision shooting, and a fibre-optic front sight with a fully adjustable rear sight provide back-up. The all-weather synthetic stock features a rubber buttpad and molded handholds. The Syrix air rifle has 4-lb. trigger and an automatic safety that engages when the barrel breaks for reloading.
