Introduction
Pre-charged pneumatic (PCP) air rifles represent the pinnacle of modern airgun technology. Originating from designs dating back to the 1780s, today’s PCP rifles combine sophisticated engineering with match-grade accuracy. These rifles, which store compressed air in an onboard reservoir, have revolutionized the airgun industry by offering unprecedented shot-to-shot consistency, power, and accuracy. From Olympic competition to advanced hunting applications, PCPs have established themselves as the premier choice for serious airgun enthusiasts and professionals.
