Ruger 90482 Bolt Shroud 6061-T6 Aluminum Black Anodized

The Ruger 90482 Bolt Shroud transforms standard bolt rifles with precision-machined 6061-T6 aluminum construction and military-grade black anodizing. This aftermarket upgrade replaces factory plastic components with aircraft-grade materials that resist corrosion and maintain dimensional stability under extreme conditions.

What Makes This Different

Unlike standard polymer shrouds that can crack under temperature extremes, the 6061-T6 aluminum construction provides superior strength-to-weight ratio and thermal stability. The Type III hard anodizing creates a surface hardness of 65+ HRC, significantly outperforming factory coatings. This shroud maintains consistent performance from -40°F to 200°F operating temperatures.

Key Features

• 6061-T6 aluminum construction for maximum durability and corrosion resistance
• Type III hard anodized finish in matte black for reduced glare and enhanced protection
• Precision CNC machined to exact OEM specifications for perfect fit
• Lightweight design adds minimal weight while improving strength
• Compatible with standard Ruger bolt assemblies and safety mechanisms
• Corrosion-resistant coating withstands harsh weather conditions
• Easy installation with standard gunsmithing tools

Field testing demonstrates consistent performance across temperature ranges where polymer components often fail. The aluminum construction eliminates flex under bolt pressure, maintaining precise headspace and improving overall rifle accuracy. Professional gunsmiths recommend this upgrade for competition rifles, hunting applications, and duty weapons requiring enhanced reliability.
