I like the case and cover as well. I think a zip on cover is better. If actually flying a snap on cover looks like it might come off.

These cases are more for car use. Real works of gunmzking accessory art. I have some old frayed ones and modern generic ones. A bespoke one or three would be nice.

In the old days I had a duffel with a bottom section I could fit a takedown case in. Hassle free anonymous travelling. I remember forgetting to declare my rifle on an internal flight or two. Never declared my rifle going into Hwange National Park. Don't think it was allowed to bring it in. Take a rifle into hotels without any hassles. Takedown case in a duffel or suitcase.

Ammo in a small locked case. Fly it in cargo separately. Nowadays gun case, fly it separately. Then both in a big duffel for travelling. Does end up weighing a lot.

I'd get a more solid metal one made for cargo luggage use.
