I saw it, cause I instantly knew this was going to be one of those "find the product we're selling" adverts.
My suggestion would be to affix the thing to the wall and unload a clip of the largest caliber firearm/airgun you can at; the largest that doesn't cause significant damage. Steel strike plates for body armor are thinner than the Torq, and usually just shrug off small rounds with only a lead smear to show for it.
Also, not sure how brass actually holds up in the long run, but alternatively, you could get that gold finish by doing a titanium nitride coating on a steel alloy. I'm guessing you'd have to 'outsource' that operation, though.
