Description
The Magpul RSA (Rail Sling Attachment) installs on any MIL-STD-1913 Picatinny rail to provide a sling attachment point for clip-on slings such as the Magpul MS2, MS3 and Paraclip. The loop gives a wide range of motion for easy rifle handling while its low profile keeps it from obstructing optics or snagging on gear. Precision cast from case-hardened steel with a QPQ salt-bath nitride finish, it weighs 1.3 oz and Magpul rates it to withstand forces up to 300 lb. Made in the USA; NSN 1005-01-591-6119.
