What section should I list an item for sale?

I have an Yankee Hill AR top end I am looking to sell what section of the classifieds should I list it in? Firearms,
Accessories & Ammunition, or in the everything else section?

Heh. That's something I hadn't thought about before, but as you aren't selling a firearm, I would suggest "Accessories".

Perhaps another staff member will chime in because I'm not 100% sure what to tell you, and I have to step away for a bit so I can't look into it at the moment. (Apologies)

I would agree it should go in Accessories. "Everything Else" is for items that are clearly NOT firearm related, which doesn't apply to your upper.

Thanks for your help gentleman.
