I'd appreciate any insight about what to expect at the show this weekend. In general, I'll be just browsing but looking for the following:
1) USGI mags
2) Cool accessories for AR-15's (even though I still have to wait another month or 2 for Armalite to ship my new rifle)
3) Handguns
4) Knives
5) Scopes

One question, if I choose to buy a gun at the show, what kind of red tape and background check should I expect? I have a state CCW permit. Will that help?

What % of private sellers vs. established businesses usually exhibit at these shows? For example, is it likely that Armalite, Bushmaster, etc. will show their wares?

Are there any vendors that I should avoid...any that I should pursue?

TIA for the advice and comments.
