Bushmaster 2000
The Bushmaster 2000 is an electro-pneumatic paintball marker released by Indian Creek Designs. Designed for with tournament-style speedball, it can shoot more than 20 paintballs per second. This paintball marker utilizes two valves to monitor airflow; a high-pressure regulator which is averagely set at 200-275psi and a low pressure control device which is set to the standard 75-90psi. The Bushmaster functions with the use of a ram-actuated poppet regulator. The Bushmaster 2000 is usually termed as a “B2K” or a “B2KX” (X stands for the year of that particular model). The 2004 modern model is recognized as the B2K4. It was recently suspended yet was restored with the same though more developed Promaster.
The Bushmaster 2000 is successfully of similar design as the Bob Long Defiant so the usual pieces can be interchanged between the two markers.
Improvements
Many enhancements are easily accessible for the Bushmaster series markers such as the valves, boards, frames, triggers, feednecks, bolts, ASAs and regulators. 2003 model and previous models utilize ICD threaded barrels, the 2004 on the otherhand and some 2003 models make use of the Autococker barrel threads. Aside from the barrels, the single compatibility dissimilarity between the models is the cabling harness or board. Some models make use of the 22-pin wiring whereas the 12-pin is more commonly used. A 22 pinboard can be wadded into a 12 pin control and will operate accurately excluding in the paintball detection system. An anti-chop eye system, which is the PDS(Paintball Detection System) is the most accessible stock in 2003 and more recent models can be fitted by competent suppliers. PDS utilizes a sender and receiver photocell that spots the successful loading of a paintball into the marker’s breech. If the ball is not successfully loaded, the marker will not fire. This facet significantly diminishes the possibility of chopping a paintball when it is not totally supplied into the breech.
Operation
The function of the Bushmaster 2000 is the same to that of the Impulse, Intimidator or other poppet-valve operated electropneumatic markers. The paintball marker is considered as open-bolt which means the bolt is total-back position prior to the firing series.
When the trigger is tugged, an electronic microswitch propels a signal to the markers electronic board signaling it to start the firing series. The board then takes action and propels the solenoid. When the solenoid valve is initiated, the air that controls the hammer in the full-back position is re-directed via the ram assembly thereby pushes forward the hammer at a fast speed. The hammer then opens the valve in about 6-16ms (this time is called the dwell). Since the markers bolt is connected to the hammer, it simultaneously moves forward, carries a paintball, passes through the detents, and positions to a firing form. The air that travels upwards via the valve directs through the bolt and the paintball is fired out of the barrel through a mixture of air pressure and kinetic energy imparted from the bolt action. As soon as the lapse of the dwell time, the solenoid goes back to the hammer onto the full-back form by directing the LPR-supplied air back via the default channel.
