Real Action Markers are designed to replicate the physical features, weight, and function of their firearm counterparts to provide law enforcement and the military with the best possible training tool available. These tools, which fire .43 caliber paintballs, or .43 caliber runner balls for training exercises, remove the risk of live ammunition accidentally making it onto a training course and into a real firearm, thus creating an environment where tactical mistakes are still realized, but not life threatening.  Real Action Markers are the tool to take your tactical paintball game to the next level!
