Key Benefits & Features
Enhanced Accessory Compatibility
With the integrated Picatinny rail, you gain the flexibility to mount micro red-dots, flip-up sights, lasers, or lights directly onto the gas block — expanding your platform’s utility beyond standard AR configurations.
Proper Alignment for Free-Float Handguards
Upper-receiver height placement helps ensure the gas block’s top rail aligns seamlessly with your receiver’s rail, achieving a continuous rail line. This makes handguard installation and accessory placement more consistent and visually cohesive.
Lightweight Construction
By choosing anodized aluminum, LBE Unlimited delivers a gas block component that minimizes added weight while maintaining structural integrity. This smart material decision supports performance without adding unnecessary bulk to your rifle.
Industrial-Grade Finish
The black anodized finish delivers both function and aesthetics: it resists wear, minimizes glare, and preserves the component’s appearance through rigorous use.
Ideal Applicant & Use Cases
Custom Builders: Perfect for those assembling an AR from parts, who want a high-quality gas block that supports upper rail alignment and accessory mounting.
Upgrades & Rebuilds: If your current gas block lacks mounting options or height compatibility, upgrading to the ARRGBUH adds modern capability and visual cohesion.
Gunsmiths & Professionals: Having a dependable railed gas block in inventory offers a flexible solution for a variety of clients’ builds — from tactical to competition setups.
Range & Duty Use: Trusted for use in extended session environments thanks to its durable finish and sound engineering.
Install & Compatibility Notes
Ensure your barrel’s gas port diameter and distance are compatible with the gas block’s specification — confirm sizing before installation.
Because this is upper-receiver height, check compatibility with your handguard system and receiver rail to achieve proper alignment.
Use proper torque values and alignment tools during installation to avoid misalignment or interference.
When installing accessories on the top rail, ensure rail nuts or mounts do not interfere with the gas system or block function.
