Comment on Futuristic weapon design by Jonasrjp

Changing the magazine on that sucker would suck. The less steps there are to do things in combat, the better. On that gun design, you would have to roll the weapon barrel all the way up past your head, up in the air behind you to get ahold of the magazine. AR platforms make changing  mags easy, the magazine is right in front of your hands (humans can naturally bring their hands together in the dark, which may not seem important but trust me), and it takes a simple push of a button to drop the magazine, and another very accessible button is used to unlock the bolt from the rear.
