This is what you’ve been looking for . - Magpul Industries M-LOK Type 2 Low Profile Rail Covers

I originally bought these to install on a new Kuna . I read there might be issues but I thought they were cheap enough I’ll check them out . They don’t fit the Kuna . Magpul needs to emphasize that they are made for a slim octagonal shape hand guard . Some videos show that but I didn’t know until after . Good news is they work incredibly well on a DDM4v7. MFR hand guard is the perfect match for the rail covers . Best covers I’ve used . Aggressive grip with heat mitigation . We’ll see if they hold up . Ordered some more in ODG for another rifle .
