It's a huge show, should be a little of everything. I noticed uppers last time, they were incredibly over priced, but that was during the craze so it could be attributed to that.
Couple good sources for magpul gear. Lots of mag choices. Good for browsing for crap you didn't know you needed.
Last time I went things were way overpriced but I also went in aprilish....they had a good selection on a good bit of stuff. I was pleased with what they had and with what I bought. Im hoping prices will be down a good bit from what they were.
I'm hoping that the September Harrisburg show was a preview of the York show. Ammo was plentiful and ammo prices were not too insane, lots of guns, with reasonable prices, beef jerky, nuts, and jewelry. We'll see. T&T Reloading was at the Harrisburg show, but the y don't do the York show anymore. A shame too.
