Ok, so I just got a new upper (this one: BCM upper but with the Gunfighter comp pinned and welded). I got it on a whim when I saw that they were in stock on BCM’s website. Considering that quality BCG’s are unobtainium right now, I would like to just drop in the BCG from the upper that this will be replacing (a very similar Spikes upper). It’s one of the Spikes NiB BCG’s.
I’ve put bout 500 rounds through my current upper/BCG, and was wondering if it would be a bad idea to use my old BCG with my new upper, since I know that BCG’s do tend to wear in with the uppers they’re mated to. Thanks for any info/advice.
