Nice product that seems to hold my Sub2k very solidly in place. It took me a little time to figure out the push-pull-lock, push-pull-unlock procedure from the written instructions, but once I did, it works very well. It works great for any weapon with 3-4 open slots on a picatinny rail with sights or scope that aren’t too tall, or that you can turn sideways like I did with my Sub2k. I would absolutely recommend this product. I purchased a second one to mount a Springfield Hellion to the same Grey Man Tactical panel in my truck. The only thing I wish I could do is key two of them alike so I could have one key for both mounts instead of carrying two different keys.
