"The L129A1 has also been seen used by RAF heli-snipers on Puma helicopters deployed for the protection of the Olympic games, another demonstration that the well liked weapon is finding new roles in the force.

More exciting info in regards to the L129A1...
" Apparently, the L129A1 has also been selected for another UOR, far less publicized, which is the “Sniper No. 2 system” or "sniper support weapon" for the renewal of the personal armament and kit used by the spotter in a sniper pair (the sniper using the L115A3).
The main difference between the Sharpshooter and Sniper No.2 is made up by the sights: the Sharpshooter is fitted with a Trijicon ACOG 6X sight, compensated for bullet drop out to 1200 meters and fitted with a secondary Close Quarter Combat CQB sight on top, the Trijicon Ruggerized Miniature Reflex RMR. The Sniper No. 2 is used with a more powerful scope sight Schmidt & Bender for day engagement and with OSTI night sight for nocturnal use.
The L129A1 is issued with 20-rounds P-mag polymer lightweight magazines. The L129A1 is used in Sharpshooter role with the 16 inches barrel, but a 12 inches and a 20 inches barrel are available, and it is not absurd to assume that in the Sniper No. 2 configuration the longer barrel might be used.
Issued one per Section, (27 or more per battalion) the L129A1 is an excellent weapon, and around 1000 are the long term requirement for Sharpshooter role. While there are indications of additional orders having been placed past the initial 440, I’ve no details available. "
