據詹氏防衛周刊報導，英國陸軍採購了一批由美國Lewis Machine & Tool (LMT)製造的新的半自動 7.62mm× 51mm "sharpshooter(神槍手)"步槍。
這支SR系列樣式的步槍定名為L129A1，它採用了包含前魚骨護木的整體式上槍身，搭配20發彈匣，伸縮托以及16吋黑色不鏽鋼槍管。
其中一個主要特點為此種上槍身能迅速拆換槍管。

此採購計畫也評比了HK417 & FN SCAR, 而最後由LMT勝出.此份合約總值250萬美元將提供440支L129A1，
為了滿足在阿富汗的戰鬥部隊緊迫的需求。L129A1由今年初開始配發
該 L129A1將取代舊式的螺栓式L96狙擊槍。在英國陸軍某部隊開始提供專業L129A1培訓，並給予狙擊認證。
但是這些L129A1射手不履行原始狙擊手的角色，而是提供給小型作戰單位用以增強準確性的殺傷力。


Semi-Auto Sharpshooter Rifle
December 28, 2009: The British Army has adopted an U.S. (LMT) semi-automatic rifle as a "sharpshooter" weapon, designating it the L129A1. Weighing 11 pounds (5kg), the L129A1 7.62mm rifle has a 20 round magazine and an effective range of 800 meters. The weapon is 37 inches (945mm) long and equipped with rails for scopes and such. About one soldier per squad or platoon would be a sharpshooter, armed with an L129A1. Soldiers must be good shots to begin with, and take a training course, to be a sharpshooter, which is sort of "sniper lite." But while snipers concentrate on being hidden, as well as doing the job with one well aimed shot, the sharpshooter is mainly concerned with hitting the target with one shot at long ranges. This is essential in Afghanistan, where enemy fighters are often encountered at ranges the standard 5.56mm assault rifle has a hard time dealing with.
Semi-automatic rifles are often used as sniper rifles as well. And not just recycled M-14s. The L129A1 is very similar to the American SR25 sniper rifle, adopted by the U.S. NAVY SEALs over three years ago. This weapon is officially known as the Mk11 Sniper Rifle System (SRS).

The Mk11 is a 7.62mm weapon based on the M-16 design (created by retired USAF Colonel Stoner in the 1950s). About half the parts in the SR25 are interchangeable with those in the M-16. The Stoner sniper rifle achieves its high accuracy partly by using a 20 inch heavy floating barrel. The "floating" means that the barrel is attached only to the main body of the rifle to reduce resonance (which throws off accuracy.) The semi-automatic, 41 inch long rifle weighs 10.5 pounds without a scope and uses a 20 round magazine. This is considered the most accurate semi-automatic rifle in the world. It's popular with Special Forces and commandos because it allows a good shooter to take out a number of targets quickly and accurately. The commercial SR25 has a 24 inch barrel, but the navy wanted a shorter one for better use in urban warfare. The rifle was initially purchased for Navy SEALS and marines, but is now used by snipers in all the services, including the navys new infantry force.

係似SAM-R(美) / SECTION 5(英)
不過係16吋管, 睇個mag well係似5.56

重點係, 支新槍應該係
"single-piece upper receiver and free-floating"

所以呢支用ff ras ge應該就唔係支l129a1喇

得睇過內文後 ...

又有一篇...

UK forces are to receive a semi-automatic 7.62 mm x 51 mm 'sharpshooter' weapon to combat Taliban forces engaging beyond the maximum effective range of the 5.56 mm L85A2 assault rifle.

In a USD2.5 million deal the UK Ministry of Defence (MoD) has contracted Law Enforcement International (LEI) to supply 440 LM7 semi-automatic rifles.

The urgent operational requirement follows calls from troops on the ground for a weapon that can be comfortably patrolled with, can be rapidly initiated and provide an increased range for contacts out to 800 m.

To be redesignated the L129A1, the gas-operated weapon carries a 20-round magazine, is 945 mm long and weighs 5 kg. It will be manufactured by Lewis Machine & Tool Company in the United States, with deliveries expected to begin in early 2010.

Features of the weapon include a single-piece upper receiver and free-floating, quick-change barrels available in 305 mm, 406 mm and 508 mm. It has four Picatinny rails with a 540 mm top rail for night vision, thermal and image intensifying optics. Stock options include fixed or retractable versions.

Industry sources told Jane's that LEI beat competition including Heckler & Koch's HK417 (already supplied to specialist units within the MoD), FN Herstal's SCAR (Special Operations Forces Combat Assault Rifle) and an offering from Sabre Defence Industries.

To date UK soldiers must complete a marksmanship course to become qualified as 'sharpshooters' and are regarded as being a grade below that of a sniper. Following the introduction of Accuracy International's (AI's) .338-cal L115A3 sniper rifle, sharpshooters have been armed with AI's outgoing 7.62 mm L96 rifle. However, the latter's bolt action does not make it a suitable option for a patrolling soldier.

With the majority of contacts occurring at either very close range or at ranges out to between 500 m and 900 m, the "only organic asset" available to responding UK forces in a small-arms capacity is the 7.62 mm General-Purpose Machine Gun, with MoD sources saying that "5.56 mm weapons lack the reach to engage the enemy at those ranges".

"The 5.56 mm is sufficiently lethal at the right range, but troops need 7.62 mm for longer ranges. We should be looking at higher performance rounds with higher lethality at longer range. Research is going to filter into user requirements for the soldier system lethality programme," one MoD source told Jane's .
