That, and every SA80 in the British army has SUSAT as standard - barring those belonging to tankers etc.). Being shorter than the M16, it's more manoeuverable. Having a bayonet fixture also helps - something the latest M16 model doesn't have - they are still used... to rather good effect, most recently in Iraq - 5 to 1 odds, only 3 injuries...

Only problem is if you're a lefty.
Not quite true, not every weapon has a SUSAT but that is the aspiration.

Also, in reliability the SA80 A2 outperforms the M16A2 by quite a margin.
