Enriches the sport, inspires the reservist

The benchmark

The HK243, like the G36, continues to set the benchmark when it comes to functional reliability. Furthermore, the semi-automatic rifle is extremely versatile and very easy to handle – regardless of whether it is used unsupported or rested. The HK243 can be easily disassembled into its assembly groups for cleaning, and with good care it will last longer than one might think.

HK243 - Authentic civilian
Classic or tactical

We offer the HK243 ex works in two pre-configured equipment variants. The basic HK243 SAR variant is equipped with a polymer handguard, a polymer sight rail with dioptre sight, the classic skeleton buttstock for the G36 and a 10-round polymer magazine. In the HK243 TAR tactical version, the semi-automatic rifle features a Slim Line light alloy handguard with HKey interfaces, a light alloy sight rail with folding backup dioptre sight, the G36 Ergo buttstock from the IdZ (“Infantryman of the Future”) series, the G28 birdcage flash hider and the 10-round polymer magazine.
