Cross Armory CRG5OKRB Gen5 Glock 3-Piece Rainbow Upgrade Kit

The Cross Armory CRG5OKRB transforms standard Glock Gen5 pistols with precision-machined aluminum components in an eye-catching rainbow finish. This three-piece upgrade kit replaces factory polymer parts with aircraft-grade materials that resist wear and maintain their distinctive appearance through thousands of rounds.

What Makes This Different

Unlike basic aftermarket parts, this kit features Type III hard anodizing that creates the rainbow coloration while providing superior corrosion resistance. The aluminum construction offers 40% better heat dissipation compared to factory polymer components. Each piece undergoes CNC machining to tolerances within 0.001 inches, ensuring consistent fit across all Glock Gen5 models.

Key Features

• Three-piece kit includes extended slide stop, magazine release, and takedown lever
• 6061-T6 aircraft aluminum construction with rainbow titanium nitride coating
• Compatible with all Glock Gen5 9mm, .40 S&W, and .357 SIG models
• Type III hard anodizing provides 65+ HRC surface hardness
• Extended controls offer 15% larger contact surfaces for faster manipulation
• Drop-in installation requires no gunsmithing or permanent modifications
• Corrosion-resistant finish withstands 500+ hours salt spray testing

Competition shooters benefit from the enhanced grip surface and positive engagement under stress. The extended dimensions reduce fumbling during reloads while maintaining holster compatibility with most retention systems. Law enforcement officers appreciate the durability advantage during high-round-count training sessions, where polymer components typically show wear patterns.
