C Clips … what more can be said about them other than that they were obviously invented by the devil to torment us. The countless instructional Youtube videos on changing the humble AR-15 dust cover is testament to this.  Fortunately for me and other C Clip haters, Strike Industries took note and have developed the UDC (Ultimate Dust Cover). This nylon polymer dust cover can be quickly attached and detached without tools in 5-10 seconds. It features a number of different designs, so if you get bored with one, you can switch it to another.

See it in action here:

The UDC is retailing for $15.95 in a number of color/design combinations.
