Duration: 10:55

This guide details the installation and basic operation of underbarrel grenade launchers for the British SA80 weapon system, covering both historical Enfield adaptations and the modern Heckler & Koch AG SA80. It emphasizes proper attachment, familiarization with loading and sighting mechanisms, and crucial safety checks. The information is presented with the technical detail expected from an expert instructor like Ian McCollum.

Quick Summary

The SA80 weapon system historically required an area effect capability, leading to the development of underbarrel grenade launchers. Early Enfield adaptations faced challenges integrating with the bullpup design, while the current Heckler & Koch AG SA80 offers a refined solution with a side-opening barrel and integrated sights.

Frequently Asked Questions

What were the early attempts at underbarrel grenade launchers for the SA80?

Early Enfield experiments included a unique sliding barrel launcher on the LSW and an adaptation of the Colt M203, which required significant modifications to the SA80's trigger guard due to its bullpup design.

How does the current H&K AG SA80 grenade launcher differ from older versions?

The Heckler & Koch AG SA80 features a side-opening barrel for longer munitions, a double-action trigger, and retains the rifle's original trigger guard. It also includes a refined folding ladder sight calibrated from 50 to 350 meters.

What challenges did the SA80's bullpup design present for grenade launcher integration?

The bullpup configuration of the SA80 made integrating underbarrel grenade launchers difficult, particularly concerning the trigger guard and overall ergonomics, necessitating unique designs like the 'shed-made' guard on early M203 adaptations.

What sighting options were available for SA80 grenade launchers?

Early prototypes featured folding grenade sights, sometimes mounted directly to the side of the SUSAT optic. The current H&K AG SA80 has a dedicated folding ladder sight calibrated for range.
