Retro ARMS 14.5T Piston

The Retro ARMS 14.5T piston is engineered for performance-oriented AEG gearboxes, balancing strength and reduced moving mass for smoother cycling and reliable engagement. Precision machining and reinforced construction provide durable sector gear interface, while the 14.5 metal teeth offer consistent engagement over repeated use. Designed for builds where a balance between durability and responsiveness is important, this piston integrates well with a wide range of gear ratios and spring powers when properly shimmed and installed.
