The L22A1 is a carbine version of the SA80-series of weapons and was produced by Heckler und Koch to the same level of modification/upgrading as the L85A2. The L22A1s were I believe largely produced from converted L86A1 LSWs, the conversions being carried out over the past three years or so.
There was a proposed carbine version in the original SA80-series of weapons, but these were never adopted/issued, rumour has it that a small number were produced.
So, in short the L22A1s are all of recent production, i.e. post Op. Telic.
