Can I use any 130 BCD chainring on my fixed?
Not really realizing it before I bought my crankset, the selection of 130 BCD chainrings is pretty small. That being said, does whatever chainring I use have to be "single speed or track specific"? Or will any 130 BCD chainring work? Are the chainring bolts used then different? I know the bolts I have now are single speed bolts.
I have a KMC 710SL chain, which I rather like, so would the chainring also have to be 1/8th specifically? Might be stupid questions, apologies.

Use a single speed or track chain ring. Anything designed for use with a derailleur will have ramps on some teeth. No bueno.
You can use your 1/8th chain on a 3/32 chain ring with NO problems.
You should be able to find plenty in 130 without too much trouble.

3/32 will work but for a fixed I would use 1/8. Most of the chainrings will be 1/8 anyway. Any 130bcd will work but for fixed one that is not ramped will work better. Since it is fixed there will be more tension on your chainring while riding than on a geared bike, so you want a chainring that is just straight cut - meaning the teeth are not cut to allow for shifting. Chainring bolts are the same. Not stupid questions, everyone starts some were.

Ramps shouldn't be a big deal if your chainline is decent. They're also less pronounced on older chainrings, of which there are buttloads available super cheap.

I see you are in Portland or neighboring Vancouver, WA. Call Citybikes or Community Cycling Center in Portland and ask about 1/8" 130 BCD chainrings. Both shops service and ride a lot of single speeds and fix gears.
I would look at Sugino as my first choice. For a given $$ amount, they are probably more round and more accurately drilled and will probably make for less chain tension variation. (Sugino has made high quality chainrings for many decades. Their lower priced and quality units are still quite good. They put their efforts into the basic part, not the cosmetics.) A quick look online, I see a 48" tooth Sugino for $39 that would probably serve you just fine. I googled "130 BCD 1/8".)

Cool, thanks for the info. I actually volunteer at CCC, so I'll check next time I'm there.

As others have said, standard ramped road chainrings aren't a great idea. Here are another couple of options:
A) Treat yourself to a nice Canadian made Blackspire Monoveloce 'ring
B) Get a narrow-wide 1x ring from Wolftooth/Raceface. You'll need a 3/32 chain (and matching cog) for this option, which is not a bad thing IMHO.
