The RSA provides a forward sling attachment point for the Magpul MS2 or MS3 and other clip-in systems.
Made from precision cast black manganese phosphatized steel, the RSA attaches to any MIL-STD-1913 Picatinny/STANAG 4694 rail. The RSA has been proven to withstand stress tests of over 300 pounds yet weighs a mere 1.26 ounces.
I have used an RSA for about 2 years now on a number of different guns and have no complaints about it at all. The price is a little high for a sling attachment but you get the magpul quality and it is well worth it in my opinion. I have never had it come loose and the hook to attach the sling to is big enough to allow for quick attachment but not oversized that it will get in the way. Would highly recommend this to someone looking for a rail mounted sling attachment.
Heavy duty construction makes this thing almost indestructible.
The simplicity of the RSA allows you to mount it to any piece of rail anywhere giving you all kinds of sling options.
The only cons I can see are the price (a bit on the high end), and that on some airsoft rifles the rail sections are a bit smaller than standard and it will wobble a bit. This is more an issue with an undersized rail and not a con of the RSA directly just something to think about. Even with the slight wobble after mounted the RSA is still very much secured and I have never had a problem with it coming off.
