T68 paintball marker
The T68 marker debuted with the first generation in 2004, and has since had six revisions. It is a .68 caliber semi-automatic and full auto CO2 or HPA (high compressed air) powered paintball marker. Besides standard paintball play, the marker is also used for military simulation (MilSim), and law enforcement training - as the marker physically resembles an M16 and M4 U.S. Military assault rifle and carbines. The markers provide effective crowd control and are an alternative method for subduing individuals; the markers can fire .68 caliber Less Lethal Live Rounds, more commonly known as pepper balls - live rounds filled with powder substance that irritates the eyes and nose, similar to pepper spray.
The T68 core is a design similar in action to the Spyder markers. Primary systems (Barrel, Air System, Feed System & Trigger) attach to the core. Additional external components add to the overall M-4 look. These include a carry handle (fixed or removable with RIS weaver rail), T-charging (cocking) handle (Gen 3 upwards), pistol grip with trigger guard, faux clip housing with working magazine release, fake magazine with hollow interior (for storage), M-4 handguard assembly with interchangeable front handguards, M-4 forward sight with bayonet lug and sling loop, and either 3-position M4 Carbine or fixed M-16A2 style stock. Various barrel lengths and styles are available, from 1" through 20", with interchangeable muzzle flash suppressors or faux silencers. The barrels use Spyder threads, so aftermarket barrels are also capable of being used. Made from machined aircraft aluminum, it is extremely rugged and simple to operate and maintain. The marker is purely mechanical, with no electronic parts in its factory form. A velocity adjustment screw is provided under the stock for adjustment of the shooting velocity, and a simple push-safe safety is situated just ahead of the trigger on the core.
The sixth generation and later models feature large changes to the marker core and body to accept a working 18-round magazine. They eliminates the gap between the trigger and the magazine receiver, allowing the trigger finger to reach the magazine release button for tactical reload. The air system is completely internal and allows the unit to be self contained.
The T68 Marker can use any weaver mounted accessory and be made into any configuration of the M-16/M4 Carbine, as well as working M203 grenade launchers that can be mounted on the marker. There are also AK-47 stocks and handguards, and MP5 accessories, allowing custom configurations.
