The Yukon Magnum is powered by the ReAxis gas-piston for plenty of power, smooth cocking, and reduced vibration when shooting. The ReAxis piston launches .177 caliber pellets downrange at 1150 FPS and .22 caliber pellets at 950 FPS. The Yukon Magnum features a handsome wood stock with a rubber recoil pad on the butt and checkering on both the fore end and wrist. The RugerĀ® Yukon Magnum balances well and comes with a 3-9x32 scope to mount on the Picatinny rail on the rifle's action. Even though the Yukon Magnum launches pellets with authority, it does it quietly thanks to the SilencAir suppressor on the muzzle.
