Is there a paintball bolt action sniper?

Answer 1

Yes. Although all standard paintball guns shoot around the same distance, there are certain barrels or paintballs available that add range and/or accuracy to the marker. Besides that any marker with a longer barrel and optics could be considered a "sniper" marker.

Answer 2

There are bolt action paintball guns, that can resemble sniper like guns.

Answer 3

There are new ones every year, and many variations of the same marker. There are literally thousands of paintball markers available.

Answer 4

No, that would be impossible because the air has to compressed to force the ball out of the barrel.
