Product DescriptionThe Radian Weapons Guardian+SIX is a robust optic mount and guard engineered for Glock MOS handguns using the Trijicon RMR / Holosun 507C footprint. Built from durable 7075 aluminum and finished in black, the Guardian system integrates TRU-SEAL O-ring sealing to eliminate the need for a separate sealing plate and keep moisture out of the slide threads. Its STUD-LOK stud/nut interface delivers exceptional thread engagement, hold-down power, and shear resistance. The included SIX back-up sights provide a low, anti-glare, anti-snag co-witness solution that stays out of the way until needed, ensuring rapid and reliable target acquisition even if your red dot fails. Made in the USA and supplied with mounting hardware, this is a premium upgrade for duty, defense, or competition pistols.Product Highlights TRU-SEAL O-ring design keeps the mount watertight and removes the need for a sealing plate STUD-LOK mounting interface maximizes thread engagement and shear strength Integrated SIX back-up sights with ultra-low, anti-glare, anti-snag co-witness Precision machined 7075 aluminum construction with black finish Designed for Glock MOS slides; fits RMR/Holosun 507C footprint optics; hardware included Specs Brand: Radian Weapons Model: Guardian+SIX (Guardian Optic Mount & Guard with SIX Back-Up Sights) Color: Black Material: 7075 Aluminum Compatibility: Glock MOS handguns Optic Footprint: Trijicon RMR / Holosun 507C Included: Mounting hardware Country of Manufacture: USA UPC: 810098420341 Manufacturer Part Number: H0002 Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
