What does L85 GBP mean?

L85 GBP refers to the "L85" model of the British Army's standard infantry rifle, officially known as the L85A1, which has undergone several upgrades and is now often referred to as the L85A2 or L85A3. The "GBP" in this context typically stands for "Great British Pounds," indicating the currency used in the United Kingdom. However, without further context, it's unclear how GBP relates directly to the L85 rifle.
