Works well, and easy to use. - Strike Industries M-LOK Rail Covers, V2

I got 2 packs of these to put on my Aero ATLAS S-ONE handguard, and they work well. They easily snap in, and once in place, they don't move. As the handguard heats up, the covers make holding the rifle more manageable. The texture is great. It adds grip without being very aggressive. If you want a really grippy cover, you might want to look elsewhere. I have one problem with it. Since it's a snap on, on the bottom of the handguard it will hit the gas block, and not go all the way on. If you have a wider handguard, it's probably fine. The ATLAS is a tight 1.3" inside diameter. Overall, it's great and I'll probably use them again, but if you have some specific requirements, consider other options.
