Apparently, you missed that the device is set up on a .338 Lapua Magnum.

I agree, it seems a bit much for 5.56.

I didn't miss that at all and such a device makes some sense on such a sniper rifle or any rifle chambered for a .308 or larger. But the article said there is a cheaper 5.56 version - that's what my comment was directed at.
