About the Hatsan BullBoss

The Hatsan BullBoss is a bullpup pre-charged pneumatic (PCP) air rifle built for small-game hunting and pest control. Its compact bullpup layout houses a fully shrouded QuietEnergy sound moderator and a 23-inch rifled barrel in an overall length under a metre. Fed by a 10-shot rotary magazine and side-lever action, it is offered in .177, .22 and .25 calibers and runs from a detachable 255cc air cylinder filled to 200 bar. In .22 caliber it produces up to roughly 326 m/s (1070 fps) and around 52 J of muzzle energy.
