CITADEL AD500 Adapter Kit

CITADEL AD500 Fixed Stock & Grip Adapter Kit

The AD500 Fixed Stock & Grip Adapter Kit from Citadel is a premium upgrade designed to enhance the ergonomics, stability, and customization of the Citadel AD500 shotgun.

Engineered as a direct-fit solution, this kit allows users to install a standard AR-style grip and a durable fixed stock without requiring any modifications to the firearm.

Crafted from a custom, impact-resistant resin blend, both the stock and adapter are built to withstand significant recoil while maintaining strength and reliability.
