New from Tippmann, the Special Ops A5 is the most agressively styled marker to come from the Tippmann family, with an Mp5-SD style shroud and mag with gas-thru grip complete as standard. The MP5-SD mods are the most popular mods available for the Tippmann A5 and, combined with the A5's cyclone feed system linking the feeder to the air system to increase the hopper revolutions the faster you fire, the A5 Special Ops marker is one of a kind !!
