#11, is it okay if we just chuckled for the write-off wiuhott actually getting the joke? #27. The .50 cal. Fun to shoot, not so fun to maintain. I worked on those for several years, and you don’t know true frustration until you’ve gotten a .50 cal back into the armory with the little lever on the bolt flipped the wrong way. There’s a little switch on the bolt, and it has to be flipped forward in order for the weapon to function properly. But every so often someone thinks “flip it back so it slides in easier,” and then you can’t pull the bolt back.
