Physical Description

Third prototype for an SA80 carbine based upon a converted L85A1 rifle. Shortened barrel and gas system, fitted with an LSW handguard, with just the birdcage portion of the long L85 flash-suppressor protruding from the flat front of the handguard. To accommodate this arrangement, the gas block (with its integral front sight base) was machined off. With a perceived requirement for iron sights, a second gas block was installed further down the barrel, with its gas plug hole left unfilled and, as before, a carrying handle with its integral rear sight was installed. As per the 1989 prototype, no major changes were made to the mechanical components of the gun, other than a shortened operating rod, about 1" shorter than the full-length L85 equivalent.
