Its base is machined from Mil-Spec anodized aluminum and utilizes a coated steel loop, which accepts up to 1-1/4" webbing. With its compact and low profile design, it provides a minimal footprint, creating more hand guard real estate. Like any other Magpul M-LOK accessory, the M-LOK GI Sling Swivel features recoil / impact mitigation lugs and cammed T-Nuts for proper M-LOK engagement.
