I've been lurking here for a few months reading and trying to absorb as much intel as possible. I happily stumbled upon this forum as I was researching which PCC I wanted to buy. Ended up buying a CMMG Resolute, basically a 16" 9mm Glock mag fed carbine.
I wanted to thank everyone that has posted their experiences/issues with the RDB system, and their fixes.
I look forward to learning more, and maybe even possibly offering up some knowledge to others.
