This is an excellent addition to your paintball marker. Once installed, you will improve your accuracy and control your speed (no more hot shots). The output gauge pressure will also coordinate your speed. Once you chrono your marker, look at the pressure on the gauge. Then you know which pressure reading will give you the approximate desired speed. By controlling the volume of gas that enters the marker, you will save $$ on gas and get more shots per bottle. Use the R-2000 Regulator as a primary speed control on CO2 and as a secondary on a fixed N or HPA system. Machined from a solid block of the highest quality certified aerospace aluminum, it will fit any bottle with standard ASA threads. The tournament sleeve locks up the adjustment system for tournament play - a must, since you can't play tournament if you can't lock your speed control.
