Are these kinds of receivers discontinued?
Question: are any of these still available for purchase or are these officially discontinued? I was really hoping to get one of these, at least a stripped upper for a build.
This video is exactly what I wanted.
I love all of mine no problems with any of them I'll do video reviews soon , but like I said no problems at all and smooth operation
