Desert Tactical Arms

Biggest issue with other Bullpup designs is that when in the prone while taking cover ( if you even have cover) changing mags sucks if it takes two hands just to remove the magazine. With a single hand magazine release using either firing hand on a true ambi design, it allows you to drop the mag while you secure the fresh mag with your other hand. A cumbersome reload process often involves scooping up dirt with the fresh mag, which will shut your gun down, no matter what the design is.

Imagine your arms in the dirt, moving back and forth trying to manage insertion of a critical feed device while projectiles are zipping over your head.

I think you're greatly overstating the issue. I've watched videos of Aussie, Brit, and other bullpup-armed soldiers doing combat mag changes in the prone position, but don't recall any showing such problems as you describe.
