The CRC 1U004B is a next-generation long handguard featuring an extended gas tube cover, designed specifically for upgrading AK-series rifles and civilian AK-pattern carbines.

This model combines high durability, enhanced ergonomics, and versatility thanks to its newly designed mounting points and expanded accessory interface options.

Key Features & Updates

📍 Redesigned Lower Handguard:

• Updated Mount Geometry: Features newly engineered mounting seats for both the upper bridge and the rifle's receiver.

• Universal Compatibility: Compatible with both long and short upper bridges.

• Retains Factory Functionality: Includes a dedicated slot to store the standard cleaning rod in its factory position.

📍 Extended Gas Tube Cover:

• Full Protection: Fully covers the gas tube to protect the shooter's hands from burns and mechanical impact.

• Integrated Picatinny Rail: Features a top Picatinny rail for quick mounting of red dot sights and optics.

• M-LOK Interface: Side and additional slots allow easy attachment of flashlights, laser aiming devices, and foregrips.

📍 Proven Core Engineering:

• Drop-in Installation: Mounts directly onto standard rifle attachment points — no filing, cutting, or gunsmithing required.

• Modular Design: Comes as a two-piece set (upper and lower). The lower handguard can also be used independently.

• Flexibility: Compatible with both original factory gas tubes and aftermarket options from other manufacturers.

• Rigid Aluminum Construction: Ensures zero play/wobble and superior durability under high-volume fire.

⚠️ Important Operational Note

During firing, powder gases vent near the front section of the top cover (exact location varies depending on the specific rifle variant). If you are not utilizing the forward M-LOK slots for accessories, we strongly recommend installing a short Picatinny rail (such as the CRC 9004) or M-LOK rail covers/plugs to shield your hands and equipment from hot exhaust gases.
