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

得睇過內文後覺得佢介紹sr25多過支新槍...

唔知點解, 我覺得支l129a1應該係呢支...

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 .

(QCB) Quick Change Barrel = 快坼式槍管.
因為連發時間太長槍管過熱會張子彈COOK-OFF! (Jam 槍); 為一方法就係換管, 但係–般机槍換(free float)管係好煩! 有必要挍管! 而新一代QCB管就只要30秒完成裝坼, 回想當年射M2 50 CAL.舊式机槍換管係好煩! 新一代50 CAL.換管易好多! 連發時條管真係見紅, 唔換一定Jam! QCB對50 CAL.机槍係偉大發明! 當你打扙就會明換管快係有幾好!

其實M4系槍械甚至新型突擊步槍(eg.Steyr AUG,ACR...etc)可以比你快換槍管既用意,其實係比你可以快速根據不同任務換standard,carbine,compact長度barrel為主要目的....與機槍用意有分別,不過機槍正常都唔會用free floating設計,亦冇意思,而且free floating都負荷不到機槍既重槍管及極高既損耗...

唔知英佬會唔會得閒換下carbine管當7.62NATO assault rifle用一雞兩味...砌枝UK SCAR-H

that's exactly what i wanna say, depends on different purpose to use the suitable barrel.

I was told the Browning M2HB 50 cal. heavy machine gun is free float barrel design (which make sense with the captioned links)....... so what is your definition for fixed type barrel machine gun? Reference please? Army didn't have much choices in the old days!

Is Brittish force used GPMG fixed or float barrel by definition?

You didn't read my post clearly! I only catch the word (QCB - post#16) only and not sniper rifles! (Read it again, and don't mislead others as I didn't talk sinper guns!) But I suppose when mentioned 50 cal. machine guns most of you (some soilders here) do understand we are talking about those M2HB machine gun! Because, the term (QCB) apply clearly described on these MACHINE guns! Of course, the F88, M249 I used or even some of you guys also shoot before are also defined (QCB) rifle as well, but the definition mainly concern modularity in military application aspects, the reason is I never be stupid to bring two either long or cabine rifle barrels into the field at the same time unlike aboved-mentioned 50 cal. (specific purpose ie. burst; heat up and replace ), small bore rifles require barrel changing only account on pre-assume tecitical condition; whereas Masada rifle based on modular co-ordination concept for time and cost concern. Which this concept will be in US mil-spec. tender condition in future weapons. However, CHing you mentioned....."不過師兄你唔講都唔覺有機槍係用free floating....少之又少..........fixed barrel machine gun????......" Infact, I don't catch your meaning! If not floating design! It should be fix barrel type then? And you ask me back what is fix barrel

Well, I truely don't know and I need your advice Ching. Thx.

Note: some M249 do need extra barrel for (squarding) burst purpose. BTW: M2 machine gun are famous for long time and a lot of people knew her existance, most of western world use M2 type! M2 and M249 are very common weapon! And they both are free float as well. The term free float I associated actually within definition of floating barrel design because torque transfer are minimial into the barrel via handguard and gas regulator system, QCB are floating design and process free floating charactistic, don't just listen to people said this is right and that is wrong! Understand the overall structure of the weapon in determine the barrel system. ie. floating post little stress along the barrel. So what do you mean 少之又少??? Do you understand what floating in engineering sense? Did you read any previous posted link reference! It clearly said there.

我冇興趣再講! 因為你只識"咬"而唔識回答問題! 你勁專門! 你話唔係咪唔係law. 你咪教我地過啲係乜float!

請你再睇吓支M249QCB連regulator係咪裝死起個身到! Requlator是否主要成托支管結構? 叫得QCB.....我唔再講啦!

Biport design for effective prupose and it has movement joints to account upward force in one direction. If SR25 shoot against portective barricade with barrel touching any barricade edges! Is not a free float barrel? Any 8 inch Revolver has nothing touch against the barrel and its a fixed barrel type! Why?
