RETRO ARMS is a manufacturer based in the Czech Republic that makes custom parts for airsoft guns. They specialize in manufacturing high-quality, high-precision internal and external parts using CNC machining.
We offer products for advanced and custom-oriented riders that are lightweight and durable, using aircraft-grade duralumin.
Gearbox (Duralumin): This gearbox offers greater precision and durability than conventional die-cast gearboxes. It strengthens the heart of your electric gun. This popular product has a good reputation. Pistons (14.5-tooth full steel/nylon fiber): Designed for excellent durability even under high-cycle use.
Disassembly and assembly requires knowledge, but it allows for highly refined, high-quality customization.
