Post me up! There is a ton of retro stuff here at the show this year.
I have bought a pile of duckbill and modified 3 prongs, 2 type 2 armalite mags, a few older firepower m16/ar180 drums and the holy grail, an original xm177 barrel!
Also have seen 2 601 firitnure sets, 2 delft scopes, 2 mounts, and a small hoard of 601 small parts. That whole list was overpriced so didn’t buy those.
Will post pics later
