I think I saw a post on HK91 of yours about FAC 91 barrels, you said you would post your results after firing the weapon, I never saw your results or anyone elses. Have you shot it? How did it shoot? Are these good barrels? I ask becuase I just purchased a kit and a FAC barrel so that I don't have to shoot my 91, I would like to know if I made a good decision, thanks.
