Crowd was thin--bargains were rare, but there were some.
A guy was selling 90-95% condition Adventureline 20 round AR15 mags, aluminum followers--asking $20, but he came down to $15. Probably had 25 or 30 left.
If you want some pristine Colt NOS 70's mags, a guy was selling those for $35--but them being pristine I'd say the price wasn't insane.
Seemed like a real good day to haggle.
A guy came down to $25 for what looked to be pristine, old-school triangular M-16A1 handguards, no cracks, no chips.
For quick location on the Adventureline mags, divide the show up into a 10 square grid, 1-5 is the far back wall, going left to right, 6-10 being front/closest, left to right. Adventure line were somewhere around grid 7, pristine rebuiilt mags were at the intersection (approximately) of grid 2 and 7.
Good luck.
