To a point, you get what you pay for.
I think a lot of the hoopla around scars killing optics is overblown. If the optic is reputable and well made, I doubt you would ever see issues.
Will your scar shake apart that Chinese glass? Maybe. Probably more likely to break that sig scope than a NF or a Leupold. Part of it depends on your use case, I’d hate to be out on a hunt and downloading sigs warranty form.
As others have mentioned, buying an ADM delta mount or equivalent should help mitigate the issue. But at that point you are paying the same price for a mount as your optic. Don’t put autozone wheels on a Ferrari.
