That is where we purchased one for my sister in law's duty rifle and while qualifying with it, it flew off and went downrange. If you are going to use one I recommend predrilling where the set screws go on the barrel. We ended up threading her barrel, and did away with the adapter.
+1, I've seen this happen too a couple of times at the range when we requalify.
