Good quality - SB Tactical SBT Folding Pistol Brace for B&T APC and HK UMP

This is a very nice piece. I just wish I could use it on ordering. I was looking at several different items and I accidentally you selected the wrong one. This one is not compatible with my pick and teenager in null1913 as I thought I had ordered and I cannot find a way to adapt it to my device. Which is sad cousin Seem a lot nicer than the one that is available for my Ruger charger. I am still looking to see if I can find something to make it compatible. But something that does not make it exceed the legal limit in length.Changing it from a pistal, two a rifle. I wish I had realized when I ordered that it was the wrong one.But it is too late now and I do not see a way to return it. I know there is.I just don't see it.
