DETAILSHK433 ASSAULT RIFLE

BarrelsThe HK433 gives the shooter six different barrel length

options, allowing him to adjust the weapon to the parti-

cular operational need. As standard, the barrels are equipped with

a further-developed and toolless adjustable gas port for sound

suppressor operation and an interface for the 40 mm grenade launcher

HK269 and the GLM/GLMA1. A front sight interface and bayonet

holder can be mounted on the barrels as an option. All barrels can be

replaced at the operators and maintenance level.

Operating conceptThe replaceable lower receiver defines the desired operating concept,

thus reducing the training expenses for the shooter. Depending on the

shooting training, the shooter can choose between a G36 and an HK416/

AR-15 operating concept. All operating elements are attached on both

sides, arranged symmetrically and can be customized. „Drop-in“

solutions of the lower receiver extend the range of functions of the

weapon with respect to match triggers or trigger assembly combi-

nations.

HandguardThe Slim Line handguard is positivie-locking and connected to the upper

receiver free of backlash. It can be removed without a tool and offers

carrying sling fixing points, modular HKey interfaces on 3 and 9 o‘clock as

well as a continuous MIL-STD-1913 Picatinny rail on 6 o‘clock.

Round counter (optional)The upper receiver has a

built-in maintenance-

free round counter.

The weapons data can

be transmitted and

archived wireless. The

round counter requires

no energy supply. Data is

read using RFID

technology.

HK pistol grip ergonomicsThe grip interface is designed similar to the HK416

weapons family. Pistol grips with exchangeable grip

shells and back straps similar to the P30 and SFP/VP

series of pistols are optional possible.

ButtstockThe ergonomically

foldable and length-

adjustable buttstock

with height-adjustable

cheek rest is free

of backlash and

connected to the

receiver. The length

adjustment has five

locking positions, allowing it to be adjusted dyna-

mically to the personal protective equipment of the

shooter. Moreover, the buttstock can be folded to

the right in each locking position. Even though, the

trigger always remains freely accessible. The case

ejection port is not covered, ensuring the ability to

defend in an emergency in the transport mode.

Magazine compatibilityThe magazine well

according to NATO STANAG

4179 (draft) ensures

interoperability of the

G36 weapon systems with

HK conversion magazine

well, the HK416, and the

commercially available

AR-15 platforms.
