Upgraded Pinty Striker Compact Bullpup MKII - Precision Powerhouse Engineered for peak performance, the upgraded Pinty Striker Compact Bullpup delivers 950 FPS in .25/.22 cal with 10% higher muzzle velocity from its re-engineered exhaust valve, offering superior sealing and leak resistance. The heavy-duty hammer system boosts efficiency by 30%, ensuring maximum power from every fill of the 310cc air tank (70-80 shots). Featuring a built-in regulator for consistency, dual large magazines for rapid follow-ups, and a 21mm Picatinny rail for scopes/lights, this compact bullpup combines power, precision, and customization. With an easy-read pressure gauge and manual safety, it's built for hunters who demand reliability and performance. Warning: If filling the airgun from 0 psi, then it will be necessary to cock the airgun to remove the force of the Hammer against the firing Valve. Otherwise, the air will pass through the firing Valve and out the barrel, and the airgun will not pressurize.
