Ripcord Industries LDR1 M-LOK Rail – 11.75″



Product Description

Ripcord Industries designed the LDR1 to be a stable and rigid platform for end-users who mount items such as iron sights, lasers, and bipods to their rail. Ripcord wanted to ensure lasers did not lose zero due to the rail shifting or bending. Removing unnecessary MLOK slots in specific locations to provide added strength, lengthwise, to the rail. The LDR1 also features a longer steel barrel nut for a rock-solid foundation. Ripcord’s anti-rotation wings, indexing pin, and tight interface between the LDR1 and its barrel nut ensure it won’t shift over time.
