Magpul RSA Rail Sling Attachment

For a business built on injection molded polymer accessories, Magpul's first forays into cast metal harware have proven to be phenomenal, beginning with the Magpul RSA (Rail Sling Attachment). The milspec black manganese phosphated steel sling loop weights in at a mere one and a quarter ounce, yet has exceed over 300 lbs of force in testing.

The Magpul RSA provides a forward mounting loop for Magpul MS2 or MS3 slings, and all other slings that utilize HK style or ITW Mash clips. The Magpul RSA installs onto any 1913 Picatinny or Stanag 4694 rail interface. The placement of the loop to the side of the firearm near the bore axis ensures minimal roll in the rifle when transitioning to a slung position.

  • All cast steel construction
  • Mil-spec black manganese phosphate finish
  • Works on any standard 1913 Picatinny-spec rail
Made in the U.S.A.

    Works just like it's supposed to. I like HK clips over push button QD and this gives you the option to hook up your sling wherever you want.

    A Fantastic Addition to Any Loadout!

    Posted by Erik Dang on 3rd Apr 2015

    Before I purchased the Magpul RSA from SKD, I suffered from One Point Syndrome, in which I had to consistently hold the grip/hand guard of my rifle in order to prevent those dastardly groin slams that inevitably occur with a one point sling. Now with the RSA, I can have my rifle comfortably slung on my hip, over my chest, or even on my back! Just wonderful! And as for packaging, it was THE most secure and intact package I've ever received in the mail. 5 stars for both the RSA and SKD's shipping expedience and care!

    Exactly what I needed!

    Small and compact. I use it for a single point sling attachment on a heavy LR 308 rifle. For me it's perfect. I actually have it mounted on the upper receiver rail under my scope.
