im putting a Vortek kit in my R-9. I would like to change the barrel to a .22 Cal but when I read the description on the pyramid air sight, somebody there says the .22 barrel will not work on my .17 R9.is this right and if so is there a difference in the transfer port size. I thought it would be a 120.00 easy swap ? Can anybody shed some here please.
thanks,
Bob
