Beeman

Beeman's Quiet Tek Dual Caliber Air Rifle Combo features an advanced technology of the gas ram system that uses compressed gas in a sealed, self-contained unit that is designed to replace the mainspring in a conventional air rifle. The air rifles cock like any other barrel-cocking airgun, but the single cocking stroke compresses a cylinder of gas instead of a mainspring. When the trigger is pulled, the compressed gas expands and drives the piston forward. It has reliable performance in any weather, smoother cocking effort, and more consistent power and velocities make for a truly exceptional airgun.
