Was that too big of a noob question
My yawn wasn't for you, it was for the super long server space waste that the article took up.
If you want pins put them in.
AR astronauts never seize to amaze me. They act like the stoner rifle had as much engineering as a Elon Musk space craft.
Is simple really. In my personal opinion you do not want hardened pins rotating in a aluminum receiver. If you did, why in the world is the pin hole hardening process necessary on an AK? Its because the rotatation could cause hole egging over prolonge heavy use. . If this is the case with a steel receiver why would you want steel pins rotating in a aluminum receiver.
And for the comment on running dry.... Every mechanical object that has moving parts that produce friction needs lube.
No.... I did not read the entire waste of server space.
If I'm wrong so be it... Im sticking to my knowledge of mechanical experience and not taking every so called ExPeRT's advice as gospel.
