G3A4

The G3A4 is a variant of the Heckler & Koch G3 battle rifle, chambered for 7.62×51mm NATO. It belongs to the G3 family, a line of rifles derived from the CETME design and widely adopted in several countries. The A4 designation identifies a late variant that incorporates updated furniture and accessory compatibility while retaining the G3’s core action and reliability.

As with other G3 variants, the G3A4 uses a roller-delayed blowback operating system. It is typically capable of semi-automatic and fully automatic fire from a closed bolt, and it feeds from detachable 20-round box magazines. Sighting is carried out with typical iron sights, including a front post and an adjustable rear sight for elevation and windage. Many examples allow mounting of optical sights or other accessories and feature updated furniture such as a fixed stock and improved handguard, depending on the operator’s configuration.

Design-wise, the G3A4 emphasizes robustness and simplicity, with a chambering that provides substantial velocity and effective range for a battle rifle of its era. Its weight, balance, and reliability have contributed to its long service life in various forces, especially where 7.62 NATO performance is valued over lighter intermediate calibers.

Users and service notes indicate that the G3A4 saw widespread use with German forces and law enforcement, as well as export adoption by several other countries. While many operators have since transitioned to newer designs, the G3A4 remains recognized for its rugged build and straightforward maintenance, traits characteristic of the G3 family.
