I searched around some on THR and with Google and couldn't quite get a straight answer to my question, which is:
Is the only difference between the PTR-91 GI and PTR-91 F models is that the F model has a fluted barrel? The GI has looser tolerances to facilitate better usage of milsurp ammunition, but from my understanding does not have a fluted barrel. Does the F model also have these looser tolerances with its only difference being the barrel? Or is the F model tighter for increased precision?
