Maybe just label yours as 'customized." Best of both worlds!!!!!I consider custom, is something built specifically for you..
With that said some of us that have not got very much money like I mean regular people. We get excited that we can rattle can our stock or afford a timney trigger heck if we can afford a break to be threaded on. That is a special thing it something to talk about and it's just a bit better than your buddies rifle.
With that said I do not believe it should be marketed as custom just AFTERMARKET. The word custom just sound more up class for us to say.
