Things aren’t going so well for H&K when it comes to sales of their G36 rifle. More modern than the M16 design currently used by the US and other countries, the G36 has had a series of embarrassing failures that led to the German government looking for a replacement much sooner than expected. H&K wants to stay on that gravy train and their response is the HK433.
From the press materials:
The new HK433 is a Modular and compact assault rifle chambered for 5.56mm X45 which combines the strengths and outstanding features of the G36 and the HK416 families of assault rifles – both proven worldwide. It doesn’t matter at all weather you are right or left-handed or have trained on a G36 / HK416 weapon system of AR-15 platform: The HK433 is the solution for every scenario imaginable. Maximum functional reliability with intuitive handling combines with maximum modularity, accuracy and weapon safety made in Germany.
This Scar-esk type rifle has quite a few modern features – full ambi controls including a charging handle that out and can be put on the left side in about five seconds, 45 degree safety throw switch, folding and full adjustable stock, and three position gas adjuster.
