NexxSpeed Hop Up

This unit is designed for Tokyo Marui Hi-CAPA 4.3 and 5.1 models, as well as the 1911 series. It is a direct fit for these platforms, though we always recommend checking your specific internal setup before installation.

TDC stands for Top Down Center. Unlike traditional hop-up systems that use a side-mounted wheel or lever, this design applies pressure directly from the top, resulting in a more consistent and centered flight path for your BBs.

If you are comfortable with basic pistol maintenance and disassembly, this is a straightforward upgrade. However, it does require removing the outer barrel assembly, so ensure you have the correct tools and a basic understanding of your pistol's internals before starting.

The 7075 CNC aluminum construction provides significantly better rigidity and durability compared to stock plastic parts. This prevents the unit from flexing under pressure, which leads to more reliable feeding and consistent shot-to-shot performance.

Yes. By providing a more stable and precise adjustment mechanism, this unit helps you dial in your hop-up more effectively. This consistency is key to achieving tighter groupings and more predictable projectile flight paths at distance.
