Excellent!
Works as expected with good lock-up on a 1913 rail. I wish it were more low profile but then that would compromise the rigidity of the part. Machining looks good, no unnecessary geometry or sharp edges. Processing looks great as well and it arrived free of voids or scratches.

So far, so good
I am a veteran US Army Infantryman, Tactical Police Officer, and now Government Contractor. I use the RSA QD Rail Sling Attachment by MAGPUL to attach a 2 point adjustable sling to my rifle. The adapter is small, and unobtrusive, and functions as expected. So far, I have no complaints to list, but will update as time and use continue.
