Step up your shooting game with the Pinty Buster. Choose the high-velocity .177 (850 fps) for flatter trajectories and tighter groups, or the hard-hitting .22 (700 fps) for superior knockdown power. The 100 cc air tank provides 20–25 reliable shots per fill, while a fast side-lever action enables rapid follow-ups and minimizes reload time. An adjustable hammer spring lets you fine-tune power and shot feel, and dual 21 mm Picatinny rails — top for optics, bottom for lights, lasers, or grips — give mission-ready modularity for faster target acquisition, better balance, and quick on-the-fly setup. Perfect for small game hunting, pest control, or backyard plinking — precision, power, and adaptability in one compact PCP pistol. 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.
