Devastating, authoritative knockdown power! The Sumatra 2500 is an easy-to-cock, lever-action repeater. This precharged pneumatic (PCP) has two built-in chambers (380cc total) that hold high-pressure air (3,000 psi) from a scuba tank, hand pump or compressor. It has a two-stage adjustable trigger that is either double- or single-action. The sights are pretty unique, in that both the front and rear are adjustable. The front post can be adjusted for elevation by turning a small wheel under the post. The rear is a two-hole aperture that flips from a small to large hole and is adjustable for windage. Accuracy is the name of the game when it comes to shooting, and the Sumatra 2500 excels in that area: 3/8" ctc at 30 yds. with Eun Jin pellets. To get the most from this airgun, you'll want to mount a scope on the 11mm dovetails. The finely rifled steel barrel (1:18 RH twist) is fed by a 6-shot cylinder that makes for quick follow-up shots. The cylinder makes it easy to use longer pellets and even mix-and-match different pellet lengths and types. The adjustable power wheel has 13 settings, making this one of the most versatile powerhouses on the market! You'll get about 15 shots on high power and 25 on medium. Muzzle energy ranges from 55.08 to 26.61 ft.-lbs. Although .22 is the best caliber for hunting, the energy from .177 and .20 calibers is suitable to hunt small- to medium-sized game or pests. Comes with 2 rotary cylinders, a fill probe and a tin of Eun Jin domed pellets. A hard Plano rifle case (PL1531) is strongly suggested! Power to spare! Unbeatable accuracy!
