Castellan PDW Retractable Stock for M4 AEG Rifles - Black

Built for compact rifle builds without sacrificing stability, the Castellan PDW Stock is an excellent upgrade for players looking to modernize their M4 platform. Featuring a streamlined dual-guide rod design, this stock offers a compact footprint that's perfect for CQB rifles, PDW builds, and lightweight carbines while still providing a solid shoulder weld and multiple adjustment positions for a comfortable fit.

Constructed from high-strength aluminum and reinforced polymer, the Castellan PDW Stock is engineered to withstand the demands of regular gameplay while keeping overall rifle weight to a minimum. The low-profile buttpad provides a secure shoulder purchase, while the precision-machined guide rods allow the stock to extend and collapse smoothly with minimal play. The integrated adjustment latch makes length-of-pull changes quick and intuitive, whether you're transitioning between indoor and outdoor environments or adjusting for body armor and tactical gear.

Designed for rear-wired M4 AEG platforms, the Castellan PDW Stock is compatible with standard M4 lower receivers that utilize a PDW-style buffer tube assembly. Its compact design also makes it an excellent choice for custom SBR, MK18, and personal defense weapon-inspired builds where maneuverability is a priority.
