Questions & Answers
Will they fit into mlok slots also ?

No. They have M Lok versions.

They shouldn't melt, as Ergo states they are heat and chemical resistant. I would be just cautious to ensure the back side of the rail covers are not in contact with the suppressor.

Ergo Grip Keymod by Stuart, January 17, 2019

Great looks - Great feel by All OD Now, Verified Owner, January 30, 2018
Finally someone really knows what military OD Green looks like. Replacing my rail pads with these instead of the “OD Green” ones I have now that don’t resemble any other green on my rifle. These covers are easy fitting and have a good comfortable sec...
