I purchased 3 sets of 5 to cover most of my 15” keymod handguard, leaving open 3 holes which were enough to mount a keymod paraclip adapter. The panel kit has a nice rough texture that provides great grip without being abrasive and is perfect for either gloves or bare hands. They snap in with some effort and don’t come loose. They’re not as rubbery as the picatinny rail covers - they’re stiffer and are excellent for giving good grip while still looking cool. I also find the black BCM upper I have tends to scratch fairly easily so this also a good way to protect it and keep the handguard looking new.
