Because they are assembled wrong?
In context of what we were otherwise talking about, I pulled out my DG3 to check weight and my trainer / fmr 11B friend put it on. So excited by the comfort, not just because Crossfire awesome, but because:
His MOLLE II pack (all of them, from Basic to AFG, including the paid for replacement after first issue one stolen) dug in. The plastic frame against his back was uncomfortable.
The frame? Against your back?
Made him stop, showed photos of proper config. "The plastic frame dug in?" Yup. NO shoulder strap unit with the pad your shoulder blades ride on. Just Two Shoulder Straps, attached direct to the frame. Swears on a stack of bibles he is recalling this properly.
Anyone else encountered this?
Seemed to be why they would overload the assault packs when they could. Anything to get away from the MOLLE II ruck as configured.
