MRSP?
Been asking this for (shocked at the realization) a decade. You may have more luck finding a parts kit elsewhere and importing. I found a 18" barrel and all parts minus the receiver - was worried major fitting would be required but worked out close enough even if tighter than the original...Can someone with a connection to orders from Norinco ask if they could do a batch of 3" chambered JW2000 with 28" or 30" barrels? An affordable 3" SxS with eternal hammers and hunting length barrels would fly off the shelves. I never understood why they didn't at least offer a spare barrel in 28" or a 2 barrel set
