AR15 upper protector

*** in the meantime, I found the root cause of my problem and solved it. I'm just keeping this thing online in case somebody is interested in it. ****

Do you have the problem that the extracted .223 Rem cartridges flip around and leave nasty scratches in the upper reciever of your AR?
Well, I do... And it pi**es me off.

So I made this little protector. It fits right onto the very end of the weaver rail, so it should not conflict any scope mounts. Won´t fit if you have the carry handle of the M16!

Edit: after the first version worked well, I made a black one. The white one was good visualisation, but looked absolutely awful on the gun... as you can see
