I've got a barrel that listed for sale it's already sold and I need to take the post down but nothing is indicating how I do that. Somebody please help me.

For sale 24" created ,fluted, .338 Federal barrel for DPMS low profile receiver. Includes carbon fiber handguard and VAIS Brake. Work done by Compass Lake. 200$ for barrel and parts. I don't know if I'm in the right place putting this up but I couldn't figure out how to do it anywhere else. Somebody please direct me to where to put this.
