It's like with their civil defence version of their stoner rifle. It was so detached from reality. They both seemed to have a complete lack of understanding about how military issue rifles need to be rugged.
Ian in particular has made remarks in the past about how soldiers just break stuff, I think he used that old cliché about them being able to break a ball bearing if left alone in a room with it. Soldiers don't just take their rifles out of their rack for a few hours to larp as operators. They have to carry their rifles with them everywhere for weeks on end. They get knocked about, exposed to all sorts of crap, and usually never fired until a range package at the end of an exercise. If he could follow say a mechanic in an armoured unit over a three week exercise where he has to drag his rifle along as he works on vehicle, he'd see how much abuse they need to be able to take.
