About Umarex

The first steps led to the first big success: Umarex developed a line of guns with powerful appeal to 10 million recreational shooters. Umarex began its expansion in the 1970s by exporting to Egypt, France, Italy, Austria and Switzerland.

The leader in air gun innovation, Umarex USA, is setting the pace once again with an industry-first double barrel air archery gun. The Umarex AirSaber Elite X2 double barrel air archery gun is powered by air-- 4,000 psi of it. Equipped with a 240 cc onboard tank, the AirSaber Elite X2 will send 25 shots from its barrels at big-game-lethal velocity. The first five shots will all launch above 450 FPS and 130 ft-lbs of energy. Accessing the second shot just requires the press of a push-through barrel selector and an optic of your choice can easily be secured to the Picatinny rail section on the top. Additionally, the front has three rail sections to assist in mounting quivers, bi-pods, or other accessories. Included in the box: The AirSaber Elite X2, 3 AirSaber Arrows with 100 grain field tips, one fill probe, and the owner's manual.
