Heckler & Koch, GmbH's HK 433 was designed and unveiled in 2017 and has only been adopted in small numbers by certain German special police units.  Its design was intended for modularity in a compact package, however its low production numbers have left the design largely devoid of any aftermarket support.
The HK 433 was shown to a select few at SHOT Show 2017 in Las Vegas, NV and was introduced to the world at EnforceTac 2017 in Nurnberg, Bavaria, Germany shortly after.  The most notable appearance of the HK 433 was in Activision's 2019 "Call of Duty, Modern Warfare" where it was re-branded as the Kilo 141.

HK 433 Features

The HK 433 is a select-fire gas-operated rifle that operates on a short-stroke gas piston and AR18 style action with a multi-lug rotating bolt.  The rifle is available to law enforcement and military units with multiple barrel lengths and is capable of semi and full auto fire.  The rifle has a full-length top rail for mounting any optics setups imaginable and we’re never going to see it except as an airsoft gun because HK restricted sale to LE/MIL.

HK 433 Capacity

The HK 433 is chambered in 5.56x45mmNATO (.223 remington) and is also available in .300 Blackout.  This rifle can accept all AR15 pattern magazines.  Though its standard capacity is 30 rounds, the shorter 10 and 20 round magazines can be used as well as the larger 60 and 100 round quad-stack magazines.  Due to the magazine well having identical geometry to the AR15, the HK 433 is able to accept 60 and 100 round drum magazines.


The HK 433, when built with a 16 inch barrel, measures 38.2 inches long with an unloaded weight of 7.5 pounds.  Naturally, different barrel lengths change the length and weight of the rifle.  The 433’s design offers nearly identical mobility to other modern assault rifles, though its folding stock gives it an edge over AR15 pattern rifles by making it easier to climb in and out of vehicles with the HK433.

HK 433 Ergonomics

Ergonomics
The HK 433 has fully-ambidextrous controls that are heavily based on the AR15.  The main differences include a bolt release lever located between the trigger guard and magazine well and a charging handle located over the handguard on both the left and right side of the rifle.  The folding stock can be adjusted for length of pull, the comb can be adjusted for different cheek welds, and the rifle can be fired with the stock folded.

HK 433 Fit & Finish

The HK 433 is built with receivers made of 7075-T6 aircraft grade aluminum that is type-3 hard anodized for resistance against damage from weather and wear.  The front handguard has KeyMod slots on the left and right side and a MIL-STD-1913 Picatinny rail on the bottom.  The folding stock is made of polymer.
