Airsoftjunkiez features a custom HPA system built into a Kriss Vector airsoft gun, which the company has been continuously refining. This specific build features a Polar F2 engine, is set for one joule of energy, and is demonstrated using 30-gram HPA BBs. The build also includes a tracer unit and utilizes the stock barrel, with the host noting that the stock barrels now work very well and don't necessitate purchasing expensive aftermarket barrels. They conduct a shooting demonstration and an invitation for viewers interested in a Kriss Vector to contact Airsoftjunkiez for various customization options, including drop-in kits and full builds.
