Interesting place to put the mag. Reminds me of the G-11 or the P90. Ergonomically effecient, though.
The mag placement was inspired by the P90, so it's no surprise that the reminder is there for you to pick up on. The weapons are desgined to be compact and ergonomically pleasing, because nothing sucks more than a rifle that is a hinderence to movement and is uncomfortable to shoot.
