 According to Steyr, their compressed-air cylinders have storage capacity for about 180 shots.A distinctive feature designed by Steyr and called the "stabilizing system" incorporates a small tungsten piston to compensate for the impulse caused by the movement of the pellet and some other internal parts in an attempt to stabilize the pistol during discharge.Further, the barrel has three holes drilled on top along its length and a muzzle brake to counteract muzzle rise and reduce recoil.
