SA80 is the designation for a revolutionary family of assault weapons and, on its introduction, it proved so accurate that the British Army’s marksmanship tests had to be redesigned.
SA80 A2 comprises the
- Individual Weapon (IW); and
- Light Support Weapon (LSW):
- It has a heavier and longer barrel than the SA80 individual weapon allowing greater muzzle velocity and accuracy.
- When fired from the integrated bipod and using the standard SUSAT sight, the LSW is accurate and consistent. It can fire 610 to 775 rounds per minute out to a range of 1000 metres.
These are the British Army’s standard combat weapons. Made by Heckler and Koch, they fire NATO standard 5.56 x 45mm ammunition. The SA80 can be fitted with the SUSAT sight and a Common Weapon Sight, which is a third generation Image Intensification (II) night sight.
Both weapons have been modified in light of operational experience. A major mid-life update in 2002 resulted in the SA80A2 series – the most reliable weapons of their type in the world. This reliability is combined with accuracy, versatility and ergonomic design. It is considered a first-class weapon system and world leader in small arms.
The SA80 A2 is expected to be upgraded to the SA80 A3.

Underslung Grenade Launcher
The SA80 Underslung Grenade Launcher (UGL) system consists of a Heckler & Koch AG-36 40mm grenade launcher and EO Tech holographic sight wedded to an ISTEC range drum. The UGL allows fire teams to deliver effective fragmenting munitions out to 350 metres. Advantages of the system are low recoil, ease of use, reduced ammunition weight and ability to have a chambered grenade at the ready whilst continuing to fire the SA80.
Ammunition Types
The system is currently fielded with Practice and High Explosive ammunition natures. There are six UGLs per platoon resulting in greatly increased flexibility and weight of fire.
Longer term enhancements to the system may eventually include a fire control system, extended range ammunition and buckshot rounds for close-quarter battle.
Cost
The costs (excluding VAT) for the SA80A2 are:
- Basic fit: approximately £1,000.
- Equipped to fight (does not include night sight): approximately £4,000.
It is important to note that purchase prices vary depending on quantities ordered (the above figures relate to the most recent purchase prior to August 2017).
The total cost of the SA80 A2 ugrade by Heckler & Koch was £111 million (ex VAT).
The cost of the SA80 A3 upgrade, of an initial 5,000 weapons, is estimated at £4.4 million (ex VAT).
