Description Redline SFR Regulator With HPA Line The SFR is Redline Airsoft’s newest regulator. It combines high sensitivity and a super fast refresh rate with a high flow design. It performs equally well whether powering an air sipping PolarStar “Jack” at 40 PSI or an air hungry Daytona gun at 120 psi. It also works with both standard high output and SLP/ELP type low output tanks. Ideal for use with all HPA engines.
