Note: this review is of gen 3 micro roni stabilizer glock pistol carbine conversion - CAA Micro Roni Stabilizer Pistol Carbine Conversion for Glock - Non NFA

First, let me say that this PCC chassis is exactly as the reviews said it would be. That would include the YouTube videos from CAA Gear Up, 704 Tactical, and their comments sections. Here's the run down: 1) the fit is secure with my Glock 17 (it will not work with Poly80 lowers as built); 2) construction is solid, but there are some sharp surfaces near grip/thumb position that are easily smoothed out with fine grit sandpaper; 3) the folding brace that comes with the Gen 3 is a bit short for a good cheek weld (I remedied that by buying the extended stabilizer from CAA for another $75; 4) the slide lock/release mechanism doesn't work very well; 5) the gen 3 is only compatible with either Glock 19/23/32 or Glock 17/22/31 (not both), and; 6) like many commented, the "charging handle" has potential to come off when dismounting your pistol from the frame. This presents more of a problem if you use the SBR version, so I'm not too concerned. However, CAA did fix issues 3, 4, 5 and 6 stated above in their next generation design. Had that version been available at the time of purchase, I would have gone that route.
