It was The Firearm Blog that first caught the scent that website of Heckler & Koch as been updated with new weapons. Whilst they are the first to actually report this as far as Google search reveals, they have no idea when the new information about the HK233 and HK233K rifles have been uploaded.

But anyway, the first thing that you will react upon seeing the initial photos of the HK233 and HK233K (K for “Kurz”) is that they are the latest reincarnation of the G36 series. Indeed, as the product page admits, these are rifles based on the G36 with increased performance.

According to The Firearm Blog, they are similar to Sporter Basic Variant of the HK243 S SAR which is a semi rifle available to the civilian market. So there is a death of information and we most of us can work on are on the information provided by the product pages so here they are:
