Too narrow at the pic rail - Magpul Industries RSA QD Rail Sling Attachment

I like the intent of the design (steel) but the single locking screw does not allow enough clamping force for the somewhat narrow width of the adapter to give me a good feeling about hanging a heavy rifle from the adapter. The single clamping screw head does incorporates both a Flat Head slot and an Allen hex drive but the Allen is easily stripped because it is so small. If the single screw used a larger Allen head................I'd feel much better about it. This one should work fine for a light rifle. I prefer slightly wider adapters which use two Torx type screws to clamp the Pic rail.
