I remember a while back seeing a thread showing the member here named Treetop's entire collection. It was like 20 something ARs, each with a number beside it.
It was/is an amazing collection. I see part of it in the thread about pinned Vortexes.
Treetop, do you have an updated photo album you would mind posting, or would you post the old one you posted in the past again? It was a great album to look at for ideas on upper configurations.
It isn't 20 of them (in the first photo, but there may be more further into the thread)
Look -------------> Here
perhaps you could IM him from that thread or email
