CROSS CRGST-RD FIBER OPTIC TALL HGHT GLK RED - CRGSTRD - 046139039917
Product Description
Standard factory iron sights on slide-mounted optic Glock pistols are completely obscured by the housing and battery deck of red dot optics, leaving shooters without backup aiming references if the electronic reticle fails or loses power. Furthermore, standard suppressor-height sights often lack bright contrast points for fast sight alignment in harsh lighting conditions. The Cross Armory Co-Witness Tall Fiber Optic Sight Set in Red (CRGST-RD) resolves these clearance and visibility bottlenecks by providing a high-profile, suppressor-height iron sight set equipped with high-efficiency fiber optic light pipes inside a custom red anodized housing.
Precision CNC-machined from lightweight, aircraft-grade aluminum and finished in an anodized red coating, the CRGSTRD sight set features elevated front and rear sight profiles engineered specifically to clear popular micro red dot optics (e.g., Trijicon RMR, Holosun 407c/507c, Shield RMS) and suppressor bodies. The fiber optic rod inserts gather ambient light to create bright, rapid-indexing sighting dots, giving shooters immediate visual alignment during speed drills, tactical courses, and defensive staging.
Designed for universal compatibility across standard-frame Glock models, the Cross Armory CRGST-RD includes anti-glare horizontal serrations on the rear sight face to suppress sun glare and reflection, delivering crisp, reliable backup sighting capability for red dot equipped handguns.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment & Sight Height Matrix: Fits standard-profile Glock models (e.g., G17, G19, G22, G23, G26, G27, G34, G35, G45, G47 Gen 1-5). Note: Will NOT fit slimline Glock frames (G42, G43, G43X, G48) or MOS models requiring proprietary narrow dovetail dimensions without verifying sight notch depth.
Installation Sequence:
- Safety check the handgun, remove the magazine, lock the slide rearward, and physically/visually verify an empty chamber.
- Field strip the handgun and remove the slide assembly.
- Unscrew the factory front sight screw using a 3/16" hex front sight tool; install the Cross Armory tall front sight using threadlocker (Loctite 242) on the mounting screw.
- Use a dedicated sight pusher tool to drift out the factory rear sight and press the Cross Armory tall rear sight into the slide dovetail.
- Verify center alignment with calipers, tighten the rear sight set screw securely, and conduct manual sight picture alignment checks with your optical red dot.
Key Features
- Co-Witness / Suppressor Height Profile: Elevated sight line provides a lower 1/3 or absolute co-witness through slide-mounted red dot optics.
- High-Visibility Fiber Optic Rods: Gathers ambient light to produce bright red sighting nodes for fast target acquisition in bright sunlight and low light.
- CNC-Machined Aircraft Aluminum: Ultra-durable aluminum housing withstands slide racking and aggressive tactical use.
- Anodized Red Custom Finish: Distinctive red protective anodizing adds custom aesthetic styling while shielding against surface wear.
- Anti-Glare Rear Sight Serrations: Horizontal glare-reduction lines on the rear sight face eliminate sun wash and optic glare.
