Features & Overview
The AP5-SD features the iconic SD-style integral shroud . Built on the proven roller-delayed blowback system using HK-spec manufacturing standards, the AP5-SD delivers the same legendary reliability and soft-shooting performance the platform has been known for since the 1970s.  Ambidextrous controls and the classic HK charging handle keep ergonomics familiar and intuitive, and the included Picatinny optics mount makes it ready for red dots and low-profile optics right out of the box. 

The firearm accepts all standard HK/AP5-pattern magazines from multiple manufacturers for effortless compatibility. Each AP5-SD ships as a ready-to-deploy package complete with a factory 30-round magazine, sling, cleaning kit, optics mount, and a rugged hard case.
