The HK433 was designed by Heckler & Koch to be familiar to operators with experience using the H&K G36 and HK416 platforms. All controls are ambidextrous, and major components are modular, allowing for rifles to be configured in the field as needed.[3]

History

The HK433 was launched at EnforceTac 2017 which ran on the 1st and 2nd of March in Nürnberg, Bavaria, Germany, after the HK433 was shown to a select number of people at the earlier SHOT Show in January.[4][5] H&K is positioning the rifle as a candidate for the German Bundeswehr's competition to select a new assault rifle.[6] The H&K G36, the Bundeswehr's standard assault rifle since 1997, is to be phased out and a replacement is planned to be phased in from 2020.

Design

Available barrel lengths will be from 11 “, 12.5”, 14.5 “, 16.5″, 18.9” up to 20″, cold hammer forged and hard chrome lined with a 178 mm (1 in 7 inch) right-hand twist, six-groove barrels with hard chromium plating.[7][8] The precision is described as “far above average”. Action is short-stroke gas piston driven system similar to the HK G36 and HK 416 with gas block regulator adjustment located above the barrel. Non-reciprocating charging handle can be changed to operate from either side of firearm. All other primary controls are ambidextrous. Interchangeable barrel system. Folding adjustable butt stock with three position cheek riser. Paddle style magazine release. Aluminium alloy upper receiver is Monolithic design with full length integrated Picatinny rail system in the 12 o'clock position. Lower receiver is polymer.[9] HK has been criticized for the look of the design as it has similar design cues to the Robinson Armament Co XCR, the FN SCAR and Remington Bushmaster ACR[10] series of rifles. The HK433 features a STANAG 4694 NATO Accessory Rail at 12 o'clock that is backwards-compatible with the STANAG 2324/MIL-STD-1913 Picatinny rail. At 6 o'clock it features the STANAG 2324/MIL-STD-1913 Picatinny rail. They have also been criticized for their use of the HK proprietary "HKey" accessory attachment system at the 3 and 9 o'clock positions rather than the more commonly used M-LOK or KeyMod systems.

The HK433 appears in Activision's 2019 first-person shooter video game Call of Duty: Modern Warfare as the "Kilo 141." It is used by the fictionalized Special Air Service.
