Looking for a 31.5-32 inch type 4 Perazzi barrel with 4 mm step or ramp rib. Would prefer fixed chokes but will entertain screw-in choked barrel. Also, would prefer 0.736 or larger bore. PM me with what you have to sell. Oliver
just out of curiosity did you make a typo? 4mm is like 1/8 inch. not much more Tham a bead. just trying to help out.
