Awesome rail but qd mounts aren't anti-rotate
by Alex -
It was between this and the Geissele mk13 and decided to go with this due to it being more price friendly and the great reviews. I gotta say, it's an awesome rail and I dont regret it. It's lightweight feels great in the hands, aesthetically pleasing, super easy to install and solid lock up. Doesn't have a torque spec on the screws so I just tightened them down as hard as I could with some blue loctite and it feels extremely solid. My only complaint is that the QD swivels are NOT anti rotate. They do rotate 360 degrees which I dont like because it causes your sling to twist. which is why I knocked off 1 star. I'll be using an aftermarket anti rotate qd sling mount.
