Radian RMR Guardian Optic Guard & Sights
$210.00
The Radian RMR Guardian Optic Guard & Sights is a premium optic-mounting system engineered for shooters who demand strength, stability, and long-term reliability. Built with Radian Weapons’ renowned precision standards, this system integrates advanced sealing technology, a reinforced mounting interface, and low-profile backup sights to deliver unmatched performance in harsh environments.
A standout feature is the TRU-SEAL system, which uses strategically placed O-rings on the mounting screws to create a watertight seal. This eliminates the need for a separate sealing plate and protects internal threads from moisture and corrosion, ensuring consistent durability.
The Guardian also features Radian’s STUD-LOK mounting interface—an enhanced stud-and-nut configuration that increases thread engagement and dramatically boosts stability. This robust design improves resistance to shear forces and keeps the optic plate secure through heavy use.
Integrated SIX Backup Sights offer a reliable secondary aiming solution. Their ultra-low profile maintains a clean sight picture while anti-glare surfaces and anti-snag edges ensure smooth operation during handling or holster use.
Combining environmental protection, mechanical reinforcement, and dependable backup sights, the Radian RMR Guardian provides a fully unified mounting platform built for superior performance and longevity.
The Radian RMR Guardian Optic Guard & Sights is engineered as a high-strength optic–mounting solution designed to offer durability, stability, and long-term reliability. Built around Radian Weapons’ reputation for precision manufacturing, this system integrates advanced sealing technology, a reinforced mounting interface, and a dedicated set of low-profile backup sights. Together, these elements form a cohesive platform aimed at providing secure optic attachment and dependable sight alignment under a wide range of conditions.
Advanced Sealing and Protection
One of the defining features of the Guardian system is Radian’s proprietary TRU-SEAL technology. This system is designed to eliminate the need for a separate sealing plate by incorporating strategically placed O-rings on the mounting screws. When installed, these O-rings create a watertight seal that helps prevent moisture from entering the interface between the optic plate and the slide. By limiting moisture exposure, TRU-SEAL™ plays an important role in reducing the risk of corrosion inside the mounting threads, helping to keep the system secure and functional over time. This added layer of environmental protection is particularly valuable for users who require reliable equipment in situations where weather, humidity, or long-term storage may affect components.
STUD-LOK Reinforced Mounting Interface
Radian’s STUD-LOK mounting interface is another signature component of the Guardian system. Instead of relying solely on traditional screw-in mounting methods, STUD-LOK introduces a threaded stud-and-nut configuration that increases thread engagement and improves overall stability. This design approach enhances hold-down strength and offers greater resistance to shear forces, resulting in a system that is structurally robust. The added reinforcement helps ensure that the optic mounting plate remains secure, even under prolonged use or repeated handling. The focus on mechanical stability makes the STUD-LOK system one of the standout features of the Guardian platform.
SIX Backup Sights Integration
A key advantage of the Guardian system is its integration with Radian Weapons SIX Back-Up Sights (BUS). These sights are designed to work harmoniously with the optic guard, offering a secondary aiming solution should the primary optic become unavailable. The SIX™ sights feature an ultra-low co-witness design, allowing them to sit unobtrusively within the system without interfering with the primary optic. When needed, however, these sights are readily accessible and provide a clear, usable sight picture.
To enhance performance and comfort, the sights incorporate anti-glare surfaces, which help minimize visual distraction, and anti-snag contours, which reduce the likelihood of catching on holsters or clothing during handling. Their subtle presence ensures they remain out of the way during normal operation while still being available when redundancy is required. Radian describes these sights as a dependable “wingman,” ready to activate when conditions demand it.
A Unified and Durable System
By combining TRU-SEAL, the STUD-LOK interface, and SIX Backup Sights, the Radian RMR Guardian Optic Guard & Sights system offers a unified approach to optic protection and sight reliability. Its focus on durability, environmental sealing, and structural reinforcement makes it a comprehensive mounting platform built around longevity and precision.

XS Sights DXT2 Big Dot Sights – Yellow
The XS Sights DXT2 Big Dot Sights – Yellow are designed to deliver fast and highly visible sight alignment in any lighting condition. These sights feature a bold yellow front dot that naturally draws the eye, making sight acquisition quicker and more intuitive. The bright color stands out clearly against different backgrounds, helping users maintain focus during rapid transitions or high-pressure situations.
A low-profile V-notch rear sight supports a smooth and uncluttered sight picture. The “dot-the-I” alignment system ensures the front and rear sights are easy to distinguish, reducing sight confusion and improving accuracy when speed matters most.
To enhance low-light visibility, the DXT2 Big Dot uses a glow dot that absorbs ambient light and produces a bright front-sight glow before the tritium becomes visible. Once lighting dims even further, the tritium automatically provides steady illumination, ensuring the front sight remains easy to locate in near-darkness. The yellow glow variant offers one of the brightest nighttime sight pictures available thanks to its superior light-absorbing properties.
Constructed from durable steel, the XS Sights DXT2 system is built for long-term reliability. These sights are engineered to withstand regular use, recoil, and various environmental conditions, making them a strong upgrade for compatible handguns.

These sights feature a bright green glow dot on the front sight that absorbs ambient light, helping shooters maintain a clear aim point even before darkness fully sets in. The convex surface of the glow dot increases light absorption, creating a stronger and longer-lasting glow in low-light environments.
The DXW2 system pairs this high-visibility front sight with a low-profile V-notch rear sight. This design naturally guides the eye toward the front sight, making target acquisition faster and more intuitive. The rear sight includes a simple white stripe instead of tritium, helping prevent sight confusion during high-stress situations.
Built from durable materials and designed to fit many Glock models, the XS Sights DXW2 Standard Dot Green offers both reliability and versatility. These sights also work as a suppressor-height option and provide a lower-third co-witness with Glock factory-cut slides and RMR optics.
