I’ve shot with Corey and shot his PCC and DaVinci PCC’s. My observations I think are helpful but also isn’t comparing apples to apples….
That being said, with my ammo (140pf 115s) any blowback PCC kicks a lot compared to my MPX. I’ve shot brekke custom guns too with tailored ammo for the guns. They felt really good! BUT, I’ve still yet to shoot a PCC that is as good as the MPX. My friend just got a JP5 and his when I asked his thoughts he said “it wasn’t a game changer” compared to his AR PCC…. More to come for sure…. Back to my original point, the MPX BCG is small/light. Less reciprocating mass means less violent recoil when tuned properly. That being said, for a few hundred bucks it’s easier to get a Scheel roller delay buffer system than a JP5 $3600 price tag. Maybe I’ll change my mind once it shoot a JP5?
