This company should be able to make one for you. I think he is a member here. This link goes to the dust cover page. I have read good reviews of his work on MGO.
Veritas Machining is a laser engraving company
Send him a picture of what you want and he should be able to make it.
ETA: Phil Mumaw is his INGO username.
So I never got to buy one of the ar dust covers when the shop was open. Now I'm building another gun this time a blackout pistol. Would like a dust cover for it. Where would I be able to buy one or have one made? Or someone sell me theirs or donate me one.
I'm not sure but I believe you would need the INGO owners permission to use the logo
