The HK416C ultra compact variant of the HK416 has been introduced in October 2010. The HK416C has a high degree of component commonality with the HK416 family though the HK416C has a new retractable butt stock and buffer system. According to its specifications the HK416C, with its very short 228 mm (9.0 in) barrel for the 5.56x45mm NATO chambering, can be expected to produce muzzle velocities of approximately 730 m/s (2,395 ft/s). The firearm's precision is specified as ≈ 4 MOA (12 cm at 100 m) by Heckler & Koch. The philosophy behind the ultra compact HK416C variant has similarities with the Heckler & Koch G36C subcarbine, which was developed out of the G36 assault rifle, and the XM8 Compact Carbine design. The intended purpose of subcarbines is to provide operators with a weapon of (nearly) submachine gun or personal defense weapon size, but firing standard military rifle cartridges, for scenarios such as VIP protection, urban warfare, and other close quarters battle (CQB) situations.
