SWEEP BOLT




Air held below centerline for gyroscopic backspin

Quarter turn radius for smooth airflow

Oval opening for wider unrestricted airflow

“SofTouch Blot” insert with raised lip

Alien’s use of a two-piece bolt for the exclusive ‘below centerline’ airflow means ample room to lock the SofTouch bolt pad in place. The blowout common with others doe not happen in Alien markers.

As more testing is done it is becoming clear that barrel breaks are not usually caused by the barrel or even by a barrel that is smaller than the ball. Increasingly it is understood that transitioning the ball from the feedneck into the chamber, the bolt’s pushing the ball into the barrel and the front of the bolt hitting the paintball stack are responsible for ball breakage. The term “loading fracture” is used to describe these breaks.

Alien's SofTouch has a raised rubber lip that contacts the ball for a softer transition. Sometimes Manufacturers put a taper on the front of the Bolt to Eliminate or to cure the breakage. Unfortunately that lowers the stacked balls. The bolt then forces the stack of balls back up against the force of the loader’s feeding system. The jamming of the stacked balls causes cracked ball in the feed tube.

The large front of the SofTouch pad contact the ball and holds it away from the bolt. Years of play have shown that holding the ball away from the bolt produces the best trajectory with the Sweep System. The soft surface makes it unnecessary for the larger contact area that is needed when pushing the ball with hard plastic bolts. Alien’s soft raised lip contacts the balls before they can drop into the chamber. Loading fractures are greatly reduced by having both the chamber ball and the ball in the feedneck contacted by the SofTouch Bolt.
