This unboxing video by Samdos focuses on the GHK G45 MOS Gas Blowback Pistol, an officially licensed UMAREX product featuring a new V2 fire control system for upgraded appearance and performance. It boasts a smooth slide, stable gas efficiency, and MOS expandability, all built with GEN5 structural accuracy for modern tactical use. Key enhancements include UMAREX-authorized laser engraving, a lighter 19.5N trigger pull, and an optimized magazine output valve for consistent gas flow and FPS.
The GHK G45 also comes with a TDC-style HOP-UP for precise adjustments and is compatible with G17 GEN5 MOS and GEN3 magazines. Weighing just 504g (including the magazine), it's lightweight and durable. While it supports RMR sights, remember to buy a separate adapter plate and screws. With a length of 185mm, an 80mm inner barrel, and a 20-round magazine capacity, it uses 6mm BB bullets and performs best with 12kg gas.
