POWERHOUSE VALVE for Benjamin Marauder .25
You want ultimate power from your Marauder, look no further. Whether your wanting to add power to your stock setup or your highly customized Marauder in a larger caliber, the POWERHOUSE valve is for you.
Contrairy to what this valve is called, it’s not a Balanced Valve like most would suggest. The Powerhouse valve by Don Cothran is an easy opening valve. That means the exhaust seat can be larger in diameter then traditional valves. These Powerhouse valve kits come drop-in ready for factory .25 cal guns, but if you want to mod your gun even further, the .250 base transfer port is ready to make you smile.
