Who doesn’t love to breathe! Our Thru-Flo Rail Covers for M-LOK install in seconds without tools and protect by your hands and your barrel. The unique one piece design pops into the slot with an open middle allowing heat to leave your barrel to both maintain accuracy and prolong the life of your barrel. Additionally, the Thru-Flo panels work with all M LOK style openings that have a thickness under 3mm. Additionally these rail covers give you a great aesthetic to add some life to your platform with tasteful accents. Finally, the Thru-Flo rail covers are the lightest covers for M-LOK on the market at only 2 grams per cover!
The Thru-Flo Rail Cover were originally known as Creature Grips. We rebranded them post our acquisition from the inventor Alex Dombrowski in 2025.
MLOK style hand guards are most commonly found on AR15s but they are also common on AK47’s, MP5’s and just about any other popular tactical rifle. Check for the oblong slots on your rail and that’s the tell tail sign these will work! If you have an AR with MLOK these are the ultimate addition as an AR15 rail cover.
ZERO HARDWARE required to install these rail panels that work with the MLOK system.
The Thru-Flu covers for M-LOK were previously known as Creature Grips and invented by Alex Dombroski. We acquired Creature Grips in 2025 and excited to expand the line up in the future!
