Thought the SCAR was ugly but a mixed tan HK416 is an abomination. Have not seen a black one. Could just buy a regular black TM 416D and spay it.
The weapon comes with a modern M-LOK Modular Handguard, with three extra rails in the box allowing fully customisation. Personally I prefer the standard 416 rails, although I have rubber rail covers on the unused parts for comfort.
