Notes
The HK11A1 introduced 30-round magazine compatibility; the HK11E added a three-round-burst mode, lengthened barrel and improved sights. Greek state arsenal EBO produced a licensed variant designated EHK11A1.
Background
Because the HK11 shares its roller-delayed action and 7.62mm magazine with the G3 rifle, a squad armed with G3s could feed its support gunner straight from their own rifle magazines, a logistics trick H&K marketed heavily to budget-conscious militaries.
