Magpul M-LOK RAIL
These rails are easy to install and remove from my M-LOK rail when needed or not needed. Also is a good extra grip on the rail.

Great Pic Rail
The Magpul Polymer Picatinny rail is a fantastic accessory. I used mine to mount a flashlight to an AR handguard, but I would also trust it with a sling or bipod mount. It's that solid. Magpul are the experts when it comes to polymers, and this pic rail feels more like it's made from aluminum than polymer. The M-Loc T-nuts were of good quality, and the mounting screws came with thread locker pre-applied. The only minor issue is that you must supply your own 1/8" Hex wrench to install, none is included. Overall, a great pic rail at almost half the cost of aluminum, without giving up any of aluminum's durability, stiffness, or impact resistance.

Works fine for everything except BUIS.
Got this to mount a Troy Industries front sight to a WWSD 2020 rifle. Realized after mounting the rail that it wouldnt sit at the same height as the rail on the receiver, so its not appropriate for mounting a front sight to. Oh well. It works fine for mounting a B&T USA polymer bipod(like Ian uses on his WWSD 2020). Just gonna have to use either the Arisaka Low Profile pic rail or the one Sig makes for the Tread series. Maybe one of Lancer Systems rails would work too. Not a bad product. Great and lightweight option for mounting M-1913 accessories to M-Lok. Just dont assume itll work for a front sight like I did.
