Does anyone have any experiance with the Flint River Armory CSA45? It appears to be a well made AR45 with some proprietary parts. My main question is how does it run and how well does in suppress? It is short stroke piston driven and has a rotating bolt, which makes me wonder if its similar to the MPX. Some people say MPX is gassy while others say its great, either way I have no experiance with one.

FRA also says they will make a version in 10mm. If you could just swap uppers, that would be an added bonus. I keep looking for a .45 PCC, and the B&T APC45 has seem to run into issues, so I was hoping to see what people had to say about this.
