I just recently purchase 2x RMS mounts for my XR15pro's. I had an issue with one of the links which ecotech quickly sent out replacements. Overall the mounts are sturdy and look pretty good however could be improved IMO. I attempted to use a bolt thru to the backside with a wingnut but am not a fan of the look. I attached a pic of this. I think there should be a stud mounted to the slide piece in which the bolt comes thru and a wing nut on the backside. So what if the bolt sticks out of the backside. If it were done like this, you would see nothing but the flat plastic mount inside the tank instead of a bolt that sticks 1" into the tank with a little black cover that seems like an afterthought. I am debating on using some allthread and epoxying over the existing hole to take away from that eyesore. Its not a huge issue just think an oversight on something that could look a lot cleaner.
