I'm currently doing a build using a VLTOR MUR upper; since I'm starting from scratch I figured I'd change the ejection port cover with an engraved one just for fun. I've learned that you need to remove the forward assist / deflector module that is pinned on and install the cover from the back side.
At least this is how I think it is done..............Is there anyone who can clarify this for me, as to how to do it, or anyone who has a step by step guide/or any pics. (I may be asking for a bit much with the guide part but figured what the hell
Below is the link for all I was able to find on the matter:
Thanks for your help
