Product Description The Griffin Armament Low-Pro Rail 13" (LPR13) is a slim, ultralight, yet exceptionally rigid M-LOK handguard designed for the modern carbine platform. Engineered with a custom aluminum extrusion, the LPR13 features significant internal reinforcement that dramatically reduces flex when gripping the carbine firmly in the shoulder pocket. This innovative construction provides rigid mounting for IR laser aimers, ensuring minimal point-of-impact (POI) shift when torque is applied to fore-grip accessories or when loads are placed on the rail while shooting off barricades or with loaded bipods. Internal testing demonstrated 70% less POI shift with laser aimers compared to competing slim rail options. Strategically positioned slots throughout the rail promote rapid barrel and handguard cooling during sustained, fast-paced shooting, while maintaining the structural rigidity the LPR13 is known for. Finished in a durable black anodized coating, the LPR13 ships with all necessary mounting hardware and thread locker for a complete installation. Product Highlights Ultralight M-LOK Design: Custom aluminum extrusion delivers a slim, low-profile handguard without sacrificing strength or rigidity.
