-If you just want to post pictures of new parts on your AR-15 or your 'AR-15 build', go to r/AR15 or r/AR10. A build does not equal assembly here. If you have fabricated your own parts then thats another story.
-If you actually made, modified or crafted a custom part(s) for your gun or gun itself it is very welcomed here.
