The WE Hi-Capa 5.1K Gas Blowback Pistol is a full-metal, semi-automatic airsoft gun with a textured polymer grip for secure handling and a gas-powered blowback for crisp recoil and accuracy. Featuring a compensated slide with cut-out ports for reduced weight and better gas efficiency, this pistol offers a 30-round capacity, adjustable hop-up, and manual safety for reliable performance. Its reinforced metal parts, including the outer barrel and recoil spring rod, ensure durability, while the front rail allows for accessory attachment.
