Following on from our Knight's Armament KS-1 video last month, Jonathan takes a look at another firearm from the Project Hunter trials: the Heckler & Koch HK416 A5.

Project Hunter was launched by the UK to select a new Alternative Individual Weapon for select branches of the British Army, such as the Rangers and elements of the Royal Marine Commandos.

The shortlist of runner-ups included firearms from Daniel Defence, Glock, SIG Sauer and as shown in this video, Heckler & Koch.
