sell AR-15 parts?
I want to go shoot my dignified fab-10 this weekend (friday, actually), but I don't have a rear sight for my flattop upper. I ordered a flip up from GG&G, but I haven't received either or a confirmation e-mail from them stating that it's been shipped, so I'm assuming I'm not going to get it this week.
So, what I need to find is a store that might still happen to stock AR-15 accessories, so I can get my hands on something like a detachable carry handle that I can use.
I already checked Kerly's in Cupertino and didn't see anything in the display case with the illicit black gun parts, so maybe someone else here can recommend somewhere.
It's not really an emergency, so I don't want to drive into some hellhole like frisco or oakland, but any input will be appreciated.
thanks
