The upgraded CRC 1U020B mid-length handguard set from leading Ukrainian manufacturer KPYK combines uncompromising reliability, thoughtful ergonomics, and a sleek, tactical design. This kit is specifically engineered for AK-74, AKM, and AKS-74 platforms, as well as civilian carbines based on them.
This model features a major redesign of both the lower base and the upper cover while maintaining the line's core benefits: quick installation and maximum structural rigidity.
Key Features & Upgrades
-
Next-Generation Lower Base:
-
Re-engineered mounting points for both the upper bridge and the receiver for a rock-solid fit.
-
Full compatibility with both short and long upper bridges.
-
Dedicated storage slot for the factory cleaning rod.
-
-
Full Gas Tube Coverage:
-
The new extended cover completely shields the gas tube, offering superior hand protection and expanded grip positions.
-
Integrated top Picatinny rail for mounting red dot sights.
-
M-LOK interface slots along the sides for weapon lights, lasers, and other accessories.
-
-
Time-Tested Reliability:
-
Rigid Aluminum Construction: Crafted from durable aircraft-grade aluminum built to withstand extreme operational stress.
-
Drop-in Installation: Mounts directly to factory fitting points — no filing, grinding, or gunsmithing required.
-
High Compatibility: Works seamlessly with both original gas tubes and aftermarket alternatives.
-
Modular Design: The lower handguard can be used independently if desired.
-
Important Operational Note!
Please Note: During firing, powder gases vent through the front M-LOK slots on the upper cover (exact venting points vary depending on the specific rifle build). If you are not using these front M-LOK slots for accessories, we strongly recommend installing a short Picatinny rail section (such as the CRC 9004) or M-LOK slot covers. This prevents potential burns and shields your hands and gear from hot gas discharge.
