great rail covers, feel very nice and sturdy. absolutely NO movement at all. if you like the look of your rails, you have to get rail covers. these are nice because you can put them in front of and behind a vertical grip, flashlight, or laser too.
nice feel, matches the texture on my m4
quick to attach
quick to detach, after you get used to it at least.
wont fall off by themselves
PROTECTS YOUR RAILS!
taking them off is a 2 handed thing, gotta put it down on a table
requires a rifle bullet to take off. (or dummy bullet, or in my case a small screwdriver)
i dont really mind these cons because i dont take my rail covers off very often
