The American made Savage Renegauge will change the way you think about semi-automatic shotguns. The Renegauge can handle the hottest high-brass and the mildest low-recoil shells with the same dependability. The patented D.R.I.V. (Dual Regulating Inline Valve) gas system ensures excess gas vents before it drives the bolt, resulting in consistent ejection, less felt recoil, and a lightning fast cyclic rate for dependably fast split times. The Renegauge has been designed to fit almost any shooter. Everything from length-of-pull to comb height and drop at the heel can be adjusted to fit.
