I have a Scorpion SBR with a Binary in it and love it. Wanted the Micro till I got to handle one and it wasn't much shorter than what I already had so I saw no reason to spend another grand. I have a folding charging handle, different grip and paddle mag release. I was using the Cz mags and Magpul mags until PSA released the AKV. I buy their mags at $14 each and a 15 rd mag extension for $20. Get a 50 rd stick for $34 bucks.
