I have a couple things left over from my SBR build. Unknown manufacture AR pistol buffer tube. Has a small "ding" from where I left it rotate in relation to the sling plate when torquing. Not visible when assembled. I 30? round thru the gun for function testing prior to receiving my F1 back. SPF $20 Dual clip sling plate, works great with HK style hooks. Same type as in the photo SPF $5 If you're flexible I can meet between Springfield, Corvallis, or Canby; depending on where I'm working that day.
