||Okay rail covers, my dad's friend owns them for his real steel Daniel Defense M4.
VERY milsim and low-profile
Made of rubber, so it has a better feel than the normal plastic ones
Fits exactly where the rail spaces are
No more hand scratching or wearing a gloves
Easy to remove
Really thin so thin your practically griping the rails, it just doesn't hurt
Overall, for the price it's okay. But I wouldn't really recommend buying these unless you want that rail feeling without having to scratch your hand; or if you just want to be mil-sim or low profile.
