The SA80 A2 rifle entered service late last year. There have been no indications of reliability or accuracy problems when using the A2 in conjunction with the Rifle Grenade General Service (RGGS). Tests were conducted by QinetiQ prior to the A2's introduction to validate with the modified rifle the results of earlier exhaustive performance trials using the SA80 A1 with the RGGS. Some rifle-launched grenades no longer in use did on occasion cause damage to the A1 and its optical sight, but since its introduction into service in 1996 the RGGS has been found to be safe in this respect. For maximum accuracy it is used with a dedicated prismatic sight.
