The Radian GUARDIAN Optic Guard is designed to offer superior protection for your Glock MOS pistol red dot optic. Crafted from durable 7075 aluminum and featuring a hard-anodized finish this guard ensures robust impact protection from all angles. The innovative STUDLOK mounting system provides exceptional thread engagement enhancing hold down power and shear resistance for secure attachment. With TRUSEAL technology there's no need for an additional sealing plate as preinstalled O-rings on the mounting screws create a watertight seal. This prevents moisture intrusion and corrosion in the mounting threads ensuring long-lasting performance.
