The Sidearm Comp Series Regulator is designed to fit onto all paintball-style bottle valves (#323). This is a low pressure regulator with a maximum output pressure of 160 psi. The advantage to our low pressure regulator is that it maintains a more steady pressure. This is more important in lower pressure applications like trail ARB pressures, nailgun pressures, paint gun pressures, etc. The dual gauges show your inlet pressure and your set outlet pressure. The aluminum body features deep heat fins to absorb heat faster in high flow applications. The knurled knob features a tight rubber seal to keep the guts and threads clean and dry in harsh outdoor environments. This is the regulator that is used in the Jet Pak 2. Limited Lifetime Warranty.
