Well made, but poor design for my use. - Viking Tactics VTAC Buttstock Adapter

I bought this to use on an M14/M1A, and it put the D-ring squarely in that pressure point under my jaw. I flipped it over (defeating the purpose of where I wanted the sling positioned), and the buckle was then under my chin. Due to the design of the buckle and the way the velcro feeds through, it constantly gets stuck, making it hard to install, adjust, and take off. It's well made, like all VTAC products, but it didn't work for me. I'd recommend the Blue Force Gear over this.
