We also aren’t necessarily “fans” of pistol braces, although we do understand the need for them. This was designed to be a quick attachment that allows the brace to be rested against your cheek, and not “shouldered”. That being said, use at your own risk. We assume no responsibility for the use of any of our products. Thank you all!
