Umarex Prymex Features The Umarex USA Prymex uses a gas piston or Nitrogen Piston powerplant rather than a traditional coil spring giving the break barrel action a smoother cocking stroke and a more consistent shot cycle. This T.N.T gas piston design sends standard .177 caliber lead pellets downrange at up to 1000 feet per second enough energy for small game and pest control at reasonable range. The 18.9 barrel contributes to a 46 inch overall length balancing manageable handling with the barrel length needed for consistent velocity. Fiber optic front and rear iron sights are built in as a reliable backup sighting system whenever the mounted optic is not in use. An 11mm dovetail scope mount comes standard on the receiver and the rifle ships complete with a 4x32mm scope and mounting rings already included so shooters have everything needed to start shooting accurately from the first outing. The stock is molded from all weather polymer standing up to rain and rough handling without the maintenance a wood stock demands. At 6.17 lbs the Prymex stays light enough for extended carry during a day of pest control or backyard plinking. Backed by a reputable airgun manufacturer the Umarex USA Prymex is a complete field ready air rifle package for sale at GrabAGun.
