Not for psak47 gf3! - NcSTAR AK Cleaning Rod

Hidden within the GF3 PSAK47 there is a rivet head that, in some cases like mine, prevents full insertion of the cleaning rod. I had to sand off about three or four thread runs and taper the end to get it to fit. Confirmed that cleaning devices will still attach. I then blued, oiled and greased the threads to prevent corrosion. Now I know why PSA does not ship these with cleaning rods. They don't always fit depending on how that rivet was made. The 3 stars is not a quality rating on NcSTAR's AK Cleaning Rod, rather my disappointment in the omission within the description that some "modification" may be required.
