Halo Reach Assault Rrifle 2

I'd be in love with you if you were to make the MA37 (MA5C mk. 4) more realistic... or just usable.

I request improved ergonomics for the stock (where your head rests), removal of the "magazine grip", curve the mag, expose the mag well a bit more, improve the grips' ergonomics (perhaps remove the flashlight and add a P90 style grip), clear and add a full-length top rail and redesign the barrel cover, remove all unnecessary bulges, round edges, and reduce weight with plastics.

Go for a light, thin, 7.62 NATO bullpup carbine made for long range and CQB controlability and dominance...
I'd be extremely thankful!
Sorry for the poor grammar, I've been very sick lately.
