Better watch the video by Toronto Airsoft to find out if your jaw will drop. They feature a custom-built Hi-Capa, highlighting the possibilities achievable with readily available parts and a substantial budget. The build is based on a Tokyo Marui 5.1 Hi-Capa, known for its compatibility with aftermarket parts. The total cost of the build, before tax, amounted to $1,912. Key components include an Airsoft Masterpiece Giga slide, a Nine Ball fluted barrel, and a Holosun HE508T red dot sight. Whilst the build is impressive, it's not cost-effective, and comparable out-of-the-box Hi-Capas are available at a lower price. If you are beginner, you are discouraged against such builds due the potential for fitting issues and the need for adjustments.
