Heckler & Koch HK433

The Heckler & Koch HK433 is a modular and compact assault rifle chambered for 5.56×45mm which combines features of the G36 and the HK416 families of assault rifles.

The HK433 was designed by Heckler & Koch to be familiar to soldiers with experience using the G36 and AR-15 platforms. All controls are ambidextrous, and major components are modular, allowing for rifles to be configured in the field as needed.

History
H&K is positioning the rifle as a candidate for the German Bundeswehr's competition to select a new assault rifle. The H&K G36, the Bundeswehr's standard gun 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 right-hand twist, six-groove barrels with hard chromium plating. The precision is described as “far above average”.
