Hatsan is well known for producing some of the most powerful airguns on the market, but they've gone all-in with the Piledriver! Producing a jaw-dropping 700 FPE in .45 caliber and an even more impressive 800+ FPE in .50 caliber, the Piledriver is leading the way when it comes to big bore power. With a 300 BAR fill pressure and a 480cc carbon fiber tank on board, and a lengthy 33" barrel, you can rest assured knowing you will have all the power you need for big game hunting.The rifle maintains a manageable profile thanks to the bullpup design. This sets the action back into the stock, and keeps most of the weight relatively certered for the shooter. The all-weather advanced polymer stock is a thumbhole design, and features an elevation adjustable cheekpiece as well as a vertically and angle adjustable buttpad, to help provide a comfortable fit. Featuring Hatsan's revered Quattro trigger, which is two stage adjustable, the Piledriver is sure to be precise enough to place your shots with ease.
