Yesterday we looked at the mechanics and the history of the Sten Mk4(S), and today we have it out at the range! The very short barrel and its porting reduce the velocity of standard 115gr 9mm ammunition below the speed of sound, and so the gun is very quiet. To my surprise, the complete lack of cheek weld was not really a hindrance in keeping the sights in focus, although I would definitely prefer to have a Mk5 Sten over the Mk4 in combat. That said, the Mk4 is an exceptionally rare item, and it was great to be able to show it to you in use!
