51058 Verified — Citadel

Under UV light (365nm), real modern Citadel stock should remain completely dark or show a very faint, specific blue glow. Most fakes light up bright purple instantly.

The mount features a rectangular recoil lug that seats into the cross-slots of the Picatinny rail. This prevents forward/backward shifting under heavy recoil, specifically from .308 Winchester (AR-10) or 6.5 Creedmoor loads. citadel 51058 verified
