Kailin Yeo –
I’m not sure if this adapter fits properly on my equipment? Is the qd mechanism supposed to be stiffer upon touching firmly on my rifle’s stock?
Imran Hanafiah –
Hello Kailin, thank you for reaching out to us about your concerns with the Problue S-03-4 9/16″ Swift Adapter. The QD mechanism should be stiff when fastened securely, but it should also be easy to move when detached. If the mechanism feels overly stiff or difficult to use, it may not be properly seated or aligned with your rifle’s stock. We’d be happy to provide more guidance or support to help you troubleshoot the issue. Please contact our customer service team and we’ll do our best to assist you.
