RSA® Rail Sling Attachment – Picatinny Sling Attachment by Magpul
The Magpul RSA® Rail Sling Attachment is the professional solution for a reliable, low-profile sling attachment on your firearm. Designed for use with the Magpul MS3® and MS4® as well as other clip-in systems, this compact adapter system sets new standards in stability, durability and mounting convenience.
Maximum load capacity – minimum weight
Despite its light weight of only 1.3 oz (approx. 37 g), the RSA has successfully passed load tests of over 300 lbs (approx. 136 kg). This provides maximum safety and reliability even under the harshest conditions.
High-quality materials for long-lasting use
Made from nitrocarburized steel, the RSA impresses with outstanding wear and corrosion resistance. The robust surface treatment reliably protects the component against weather, intensive use and mechanical stress – ideal for outdoor, hunting and tactical applications.
Universal compatibility with Picatinny rails
Thanks to compatibility with the M1913 Picatinny rail system, the RSA can be quickly and securely mounted on nearly any modern bolt-action or semi-automatic firearm. The low-profile design ensures ergonomic sling routing without any obtrusive height.
