The Umarex Synergis has three primary features that are making the one-shot pellet rifle obsolete! Fixed barrel under-lever accuracy, smooth shooting T.N.T Gas piston power, and a low profile 12-shot RapidMag rotary magazineall in a great looking, easy-handling package. The Synergis departs from the conventional break barrel airgun design to give shooters fixed barrel accuracy that looks as good as it shoots. Umarex's patent-pending Airflow Boost Technology lets the T.N.T gas piston transfer air in the most efficient way possible which makes the Synergis a true 1,000 FPS rifle. Included with the Synergis is a 3-9x32 scope which mounts to the rifle's Picatinny rail. What really makes the Synergis head and shoulders above the rest is the low-profile 12-shot auto-indexing RapidMag rotary magazine. It's virtually automatic. The patented system rotates the magazine and inserts a pellet into the breech automatically every time you actuate it's easy to use under-lever cocking mechanism. Get stocked up on spare magazines, because you're going to want to shoot all day long!
