About Real HK416
The Heckler & Koch HK416 is an assault rifle designed and manufactured by Heckler & Koch. It uses the AR-15 platform, originally conceived as an improvement to the Colt M4 carbine with the notable inclusion of a gas-piston system derived from the Heckler & Koch G36. Customers have the option of purchasing a new upper receiver, buffer and drive spring to refurbish M4s or buying a completely new build HK416. The HK416 is part of the Individual Carbine competition to replace the M4.
About Umarex HK416
The HK416C is a compact assault rifle that Heckler & Koch developed and its intended users are those which PDWs are targeting: paratroopers, vehicle mounted crews, and PSD (Personal Security Detail) but it's also in the Sub compact weapon category that Colt is also working on according to the Firearms Blog. At first glance it looks like one of those Patriot M4 pistols with free float rails, but then the HK416 could easily be mistaken as an M4, the rifle it intends to actually replace, however, it's not quite achieved its objective even it's superior in many areas than the M4.
The HK416 has a 9" barrel and a shortened buffer tube to allow a retractable stock to make it even more compact and can easily be stored or carried. This versatilty then allows for more maneuverability for the user, and in this case, it is definitely more for close quarters.
