Very nice for the price! - Timber Creek AR Billet Dust Cover

I received this as a gift. I read all of negative reviews on these & wondered what they were all about? So, of course I was a little worried when my wife happens to buy me one for Christmas to go with a new Aero slickside upper. It looked great! The machine work and anodizing looked great, and I wanted it to fit. So, before going through the trouble of winding the spring, I installed it on the rod by itself. Snapped shut perfectly and seemed to have the correct amount of tension when I snapped it open manually.

I installed the spring & now it will no longer snap shut? So I immediately know it's spring related. I take a look at the back and see the longer end has a slot milled in the back of the dust cover, but the short end of the spring is getting squeezed between the receiver & the dust cover. I simply bent a 90° angle into the short end of the spring, just low enough that it doesn't get squeezed between the receiver & the cover, and now it's perfect.

Timber Creek should remedy this by either milling a slot for both ends of the spring or bending the spring end like I did. But honestly, it took me longer to find my needle nose pliers than it did to diagnose & remedy the problem. I have a hard time deducting points when the issue was such a non-issue. Don't let a spring outsmart you. If you do, maybe don't tell the world about it?
