Ripcord LDR1 – 13.13″


SKU N/A Category


SKU: 19980320-13.9

We 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. We wanted to ensure lasers did not lose zero due to the rail shifting or bending. By removing unnecessary MLOK slots in specific locations, we were able to provide added strength, lengthwise, to the rail. The LDR1 also features a longer steel barrel nut for a rock solid foundation. Our anti-rotation wings, indexing pin and tight interface between the LDR1 and its barrel nut, ensure it won’t shift over time.
