.308 Lower Help

[slowjonn]

Greetings all. I just got around to building up my Fulton FAR308 lower. I bought the parts kit and Extra parts needed from Lanworld (thanks again Chris) awhile back. I have since forgot what the third part is for. It is the half-threaded pin, not the two pivot/ take-down pins. Can someone help me out before I get too far into the build. I tried searching the forum but was unable to find the answer. Can someone direct me to a schematic possibly?Thanks again.

Never mind, I figured it out.
