The Heckler & Koch HK433 is a modular assault rifle chambered for 5.56×45mm which combines features of the G36 and the HK416 families of assault rifles.[1][2]
The HK433 was designed by Heckler & Koch to be familiar to operators with experience using the Heckler & Koch 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 first introduced at EnforceTac 2017 which went 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] Heckler & Koch offered the HK433 along side with the HK416 as a candidate for the German Bundeswehr's competition to select a new assault rifle.[6] The HK 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
The HK433 has multiple barrel lengths ranging from 11-, 12.5-, 14.5-, 16.5-, 18.9- or 20-inch. All of the barrels are cold hammer forged, hard chrome lined with a 178 mm (1 in 7 inch) right-hand twist, six-groove rifling.[7][8] The precision is described as "far above average". It features a short-stroke gas piston driven system similar to the Heckler & Koch G36 and HK416, with a gas block regulator adjustment located above the barrel. The non-reciprocating charging handle can be changed to operate from either side of the rifle. All other primary controls are ambidextrous. It has an interchangeable barrel system and a folding adjustable buttstock with a three position cheek riser and a paddle-style magazine release. Side-folding the buttstock shortens the HK433 by 266 to 297 mm (10.5 to 11.7 in). The monolithic upper receiver features an integrated full length Picatinny rail, and is made of aluminium alloy, whilst the lower receiver is made of polymer.[9] Heckler & Koch has been criticised for the look of the design as it has similar design cues to the Robinson Armament Co XCR, the FN SCAR, the Remington Bushmaster ACR and SIG MCX series of rifles.[citation needed] 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 criticised 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 empty weight of a HK433 Draft STANAG 4179 compliant box magazine is approximately 160 g (5.6 oz).
