Ideal for:
Mil-spec M4-style AR builds
Replacing worn or damaged handguard caps
Gas system and barrel component upgrades
New rifle assembly or upper receiver projects
The M4 cut design makes this cap a go-to choice for traditional AR-15 handguards and OEM-style front-end configurations.
Mil-Spec Dimensions for Seamless AR-Platform Compatibility
The LBE Unlimited ARHCR is engineered to mil-spec standards, ensuring excellent compatibility with most AR-15/M4 gas systems and barrel assemblies. Whether building a rifle from scratch or refurbishing an existing upper, this cap integrates smoothly with standard front sight bases, barrel nuts, and delta ring assemblies.
It fits securely behind the front sight base and helps stabilize your handguard, ensuring reliable performance and consistent alignment with the rifle’s receiver.
Enhances Handguard Stability and System Reliability
A proper handguard cap is essential for keeping two-piece handguards secure and maintaining the structural integrity of your rifle’s front-end components. The ARHCR design ensures that your handguards remain firmly seated, reducing movement and improving overall stability.
Benefits include:
Improved handguard alignment
