The Magpul RSA QD rail sling attachment in black (Magpul part no. MAG337-BLK) clamps onto any 1913 Picatinny rail to give you a QD-compatible sling attachment point. An anti-rotation QD socket prevents twisting and tangling, and the low-profile design will not obstruct optics or interfere with the operation of the firearm. The angle is optimized for two-point slings, which keeps the push button easy to reach. It is made of precision cast steel with a QPQ salt bath nitride finish that resists wear and corrosion.
