these mcfarland gas rings of the one piece type--anybody running them?
anybody have any problems solved by running them?
anybody have problems after running them?
i am just trying to figure out if there worthwhile or more the
"mall-ninjas just got to have them because that is what all the kool mall-ninjas have in their AR's!"
i have never seen a need for them--but the one piece gap-less ring looks logical but is it?
