[Alton Anker]

Good evening to all
I have a question on two sets of Parker repo barrels the barrels are stamped
Imp cyl and mod on both sets but when I measure them on the right barrel the restriction is six thousands and the left barrel measures twelve thousands restriction that would tell me they are choked skeet and ic what am I missing both sets measure very close to the same that would lead me to believe they have not been tampered with thanks in advance to set me stright
