Looking for a PCC and have it narrowed down to Wilson AR 9 or the JP GMR 13. Anyone own both or shot both that has any feedback they would like to give, thanks!

Anyone have any feedback on either of them?

I've never shot either one.  I think the Wilson is pretty damn new and so probably not many reviews out there.  And I'd guess there aren't that many of the JPs out there in the wild either.  Both are premium companies with great reps.  The main differences I see are the Wilson has LRBHO, which the JP does not, and the Wilson comes configured for one of Glock, Beretta and M&P magazines, whereas the JP only takes Glock.  That, and the JP is a fair amount less money.

Probably not all that helpful but that's what I've got.  I'm sure you'd be very happy with either one.  For what it's worth my build uses the JP bolt and Silent Capture Spring and runs great.

I have a CCMG 9mm stripped lower and DPMS slab side upper I am going to use in a 9mm build
thinking of going with the JP 14.5 barrel and pin/welding their comp on it and then using the JP bolt and silent capture spring
