Useful product - Magpul Industries RSA QD Rail Sling Attachment

This product has been very reliable for me. I use it with Magpul slings. It works with other qd brands, as long as they are not too cheap, and they retain good specifications. This is useful for achieving different sling attachment angles, or when you only have 1913 Picatinny type rail mounting options. This has not given me problems so far. I use the yellow or blue locking fluid included, or myself as I switch it from firearm to firearm. I would recommend this to a friend.
