The Rail Mounted Fixed Loop allows a quiet, secure sling mounting loop to railed forends. Machined from aluminum and hard coat anodized, it provides a rugged and silent sling loop on MilSpec 1913 hand guard rails (may require minor fitting on others). This Rail Mounted Fixed Loop is issued with the USMC M27 Infantry Automatic Rifle, and is also approved for use with the M4, M4A1, and M16A4.

Install by sliding loop down the rail to desired position, inserting the provided flat head screw, and tighten with any multi-tool with a flat blade screw driver (instead of odd hex head bits that get lost).
