Review on GrovTec Button Adaptor Black Oxide by Carl Durant

I bought this to use a Vickers strap. This solution avoids weird MacGyvering to secure the sling. The adapter post was slightly larger than the swivel on the main tube cap. All that was required was a light grind with a Dremel diamond head in a swivel. The QD is secure and releases with normal force. I haven't found anything that compares and I recommend it.
