H&K MG4 E.

The MG4 E is an export variant of the MG4 that has been slightly modified and is slightly lighter. The letter "E" in the designation stands for "Export". It has a different gas assembly that reduces the cyclic rate of fire. In 2007, the Spanish Army adopted this variant as their standard light machine gun. The Spanish Military of Defence ordered 1,800–2,000 of these light machine guns. Moreover, it is compatible with all NATO standard ammunitions and works with commercially available ammunition boxes and ammunition pouches. Its standard MIL-STD-1913 Picatinny rail allows an almost unlimited number of mounting options for mechanical and optical sights, thus guaranteeing full night fighting capability. Its favourable dimensions and low weight allow the user to carry the MG4 E even over long distances without getting too tired. Heckler & Koch set the standard for durability of barrels. At the same time, changing the MG4 E barrel could not be easier. Significantly it can be changed without using gloves, because the carrying grip is also the barrel change grip. This advantage comes into effect when the first barrel has heated up as a result of combat shooting. An additional key advantage: In the MG4 E, the barrel can be changed independently of the bolt position. The bipod of the MG4 E is robust and dirt resistant. It can be simply folded up and stowed away in the ergonomically formed handguard. This allows the user to hold and transport the MG4 E as comfortably as an assault rifle. It can be rotated and has variable height adjustment – absolutely necessary for uneven terrain in combat situations. The upwards protruding loading indicator is very practical. It not only indicates optically that there is a cartridge in the feed tray, but it also allows you to feel the loading status in the dark. The carrying grip also performs as the barrel change grip. When it is folded down, the barrel is locked. To change the barrel, simply fold up the grip and unlock the barrel. A safe and practical option is to lock the bolt in any position of its track. Simply lift up the cocking lever and clamp it firmly against the receiver. Activating the bolt lock prevents any accidental firing. The bolt head carrier design ensures maximum user safety in case of faulty ammunition and prevents incorrect cocking of the weapon. The carrying grip of the MG4 E is attached at an optimum angle. This ensures minimum user effort when carrying it – a great advantage when changing the combat position. The cover to the feed tray can be simply flipped open in the firing direction. This allows the cartridge belt to be changed in a matter of seconds. Another strength: While doing this, the MG4 E remains in the firing position.
