The Umarex Origin is your all-inclusive first step into the world of pre-charged pneumatic shooting. The Origin is a unique PCP that cuts pumping down by half so you can do more shooting. The patented pre-pressurized tank is fully pressurized with only 13 pumps from the included 3-stage, 4,500 PSI hand pump. To completely fill the Origin's Tank only requires 100 pumps, half of the pumps required of comparable models. The Origin is a smooth operator with its side-mounted cocking lever and included two 10-shot auto-indexing rotary magazines. With the Origin, you can spend less, pump less, and shoot more. Mount up your favorite optic on the combination optic rail and head to the range with the Origin and a few tins of pellets and rediscover how good shooting really is.
