Looks like a movie gun now. i like it a lot - AIM Sports Inc Remington 870 M-LOK Modular Rail System

The construction is a little on the thin side so it may not be super tough, but it also doesn’t add too much weight. Having the ability to add a flush-mount optic (no riser needed for most red dots) and M-Lok flashlight or laser, etc is obviously what it’s made for, and it does that quite well. There are mounting points for the receiver and the magazine tube, so make sure that you have an understanding of how it all fits together or you may throw off your mounted optics zero when you disassemble for a full cleaning.
