While that is appealing, I don't think I should be expected to spend more money fixing issues that the manufacturer should be more than willing to remedy.
I don't know who that guy is here.
Only lasted a little over 2 minutes into the video, my BS cup had runneth over numerous times by then, couldn't take any more. I come from a different generation, and his appearance alone speaks loads to me, sorry that's just who I am...
What nom de guerre does he post under here?
This is my favorite setup for a right handed user. Note the connector on the stock is on the ejection port side.

Since the Ava Tactical weapon Light mount isn't available anymore as shown in the picture, I'd recommend using the IWC light/sling mount. It will work just as well. I like the BlueForceGear padded QD sling with sewn in connectors. They have lots of color options to pick from. I recommend mounting the rear connector on the ejection port side if you're right handed. Having the sling loop to the outside will help control roll. It'll keep the sling from bunching up when shouldering the shotgun. Having the connector on the inside would poke me when I'd have the shotgun slung on my back. Previously I would have issues where the sling would prevent me from getting the stock in to the pocket of my shoulder. With it wrapped to the outside, this isn't an issue anymore.
I started slinging my rifles the same way now.
