Went today, it was excellent. Many different AR related tables, lots of different ammo with different prices. An example, SA 300 round battlepacks were advertised from $35 to $48 each. Saw .223 in SA, Greek, British, Israeli, Guatemalan and the usual US brands, Fiocci, Barnaul,Wolf, Sellier & Beloit, and others. Wound up buying some loose packed Guatemalan. 1000 rounds in a cardboard box. A little dusty, a few with dents, $86.
Mags were going for $13 - 18 for GI 30rd, $20 - 30 for 20 rd and there were even a few Sterlng 40s, $90. Orlite & Thermolds in the teens.
Only a couple of beef jerky tables and no "flea market" tables.
For $7, a pretty decent show. I'll recommend a visit for anybody within two hour driving. It's just off exit 26 of the PA Turnpike, I-276. In the Fort Washington EXPO building, the A Mall around back.
