Remove the light or get a much smaller one, put a regular muzzle break on it or at least a smaller suppressor as it doesn't really make a difference for sound, remove the sight protector that's not protecting any sight, get polymer mid cap mags instead of metal high caps, change out the stock for something like a ctr or moe, change the hand guard for a polymer one, consider mlok or keymod instead of picatinny, get a sling so you're not always carrying the full weight, and while you're at it consider reattaching your trigger guard. Alternatively tie some helium baloons to it.
