The RSA provides a low profile forward sling attachment point for our E-RUSH and RUSH Sling systems for rapid two to one point transformation. Made from nitrocarburized steel for wear and corrosion resistance, the RSA attaches to any 1913 Picatinny rail and has been proven to withstand stress tests of over 300 pounds while only weighing a mere 1.3 ounces. Made in U.S.A.

    Total Reliability

    Posted by Daryl on Feb 24 2016

    My wife and I each use this device for our rifles. Hers is a Beretta CX4 Storm with a Tri Rail and an Urban ERTSling. Mine is an Arsebal SAM7 with a Midwest Quad Rail and an Urban ERTSling . The RSA works perfctly for both applications. Matt at Urbn ERT was very helpful in configuring both of these rigs.

    Nice Addition to my PS90!

    Posted by John Frascello on Oct 21 2015

    I bought the RSA and mash clip so that I could make my sling a 2 pt or a 1 pt at my discretion. I originally ordered the "plain" mash clip (no adapter) and had to re-order. Matt had it to me in about 3 days! It is extremely easy to operate and it works as shown in the company's video. I love everything I've gotten from Urban ERT. I highly recommend this company, not only for the quality of their products but, for their fast shipping and GREAT customer service.

    Thank you, Matt.....keep up the good work you do!

    looks nice, but not the most useful without hook webbing clip

    Looks nice, but not the most useful without hook webbing clip. I will order that soon. If I had known though, I would have saved on shipping by getting it with my Hybrid Sling Order. I am pleased with the refund and customer service oversight for ordering another Mag Pull RSA because on the confirmation, it doesn't list what was selected. Will order other piece soon.
