Big improvement on the traditional pressed metal cover. - Strike Industries Enhanced Ultimate Dust Cover for AR

This is a good looking cover aesthetically. I like that it won't rust or discover like the pressed metal covers tend to. Installation and future removal is a breeze.

To remove your original dust cover without removing the handrail:
1. Remove the tiny circlip on the barrel end of the hinge pin by pushing downwards with small pliers (or something similar) with the opening of the circlip facing up. I put a small piece of tape under the circlip to prevent a scratch if I slipped.
2. Trace the path of the hinge pin back towards the stock over the assist channel and place a piece of tape along the path being sure to include the area underneath the ejection port. I use electrical tape as its resilient, painters tape doesn't protect well enough.
3. Pull the hinge pin out towards the rear, pulling upwards as you go to clear the forward assist channel.
