The 5KU Aluminium Recoil Spring Plug is a simple lightweight upgrade for Hi-Capa 5.1 GBB pistols, replacing the standard recoil spring plug with a CNC aluminium alternative. Designed as a drop-in replacement, the aluminium construction keeps weight down while providing a durable and precisely machined component for the recoil system. It's designed specifically around the 5.1-length Hi-Capa platform. Available in a range of anodised colours, it's also an easy way to add another colour-matched detail to a custom Hi-Capa build. Suitable for Hi-Capa 5.1 GBB platforms. As with aftermarket Hi-Capa components, minor fitting may occasionally be required due to differences in manufacturer tolerances and custom builds. Key Features CNC aluminium construction Lightweight recoil system upgrade Designed for Hi-Capa 5.1 Direct replacement for the standard recoil spring plug Durable anodised finish Ideal for stock, upgraded and custom Hi-Capa builds
