These turned out perfect! Just what I was looking for. I much prefer this bolt on style over the malleable clip in style. Plastic still doesn't like heat and when the snap in style gets too hot they start to warp where these will not do that. Even after heating up they stay straight because they're BOLTED in! A+ on design and good texture.

Looks great, ok hardware quality

The mounting hardware is made of steel, but seems to be machined poorly since there were a few dents in the locking nuts. Luckily only one nut was either affected by the dent, or the threads were poorly machined. Good thing I ordered 2 packs. Otherwise they look great.

So far I am pleased

I installed these on two AR's this past week and so far I am pleased. They are well made, lock in tight, have pretty good texture, and look great. After one trip the range they held firm and did a good job of blocking the heat from the barrel. Installation was a bit tedious because of how the panels are packaged, but not enough to reduce my rating.

Great option

Panels are very nice for the money and better value than the super expensive options and way better than the snap in ones

Sweet Combo!

I purchased a set of the M-LOK Slate Panels to use on my FM AR9 Pistol along with the Magpul a M-LOK AFG Angled Foregrip. A nice combo for my big hands to help make the compact AR9 comfortable to shoot. I only needed two because of the Angled foregrip filled the space on the bottom.

Good product

Happy with my purchase. Great handguard option. Think of them as less expensive rail scales

Buy these instead


These are the only rail covers I’ll buy now. They’re comfortable & the mounting hardware keeps them extremely secure. You can stipple them if you want to. They’ll hold up for you much more long term than the plastic clip-in style covers. & if you’ve got a particularly slim handguard, The 2 slot size will fit around your gas block beautifully.
