I see the Aimpoint red dot on an LT QD, 3x mag with LaRue Tactical FTS QD mount, LMT BUIS. Looks like he also has a GLIS equipped. Charging Handle had me a bit confused... its an ambi handle but the two exposed roll pins at the top had me scratching my head till it came to me. The rifle is an HK416 and that is the HK 416 version of an Ambidextrous charging handle.
