今天小編分享的軍事經驗：MG技術公司LMG-A-GP機槍亮相 中口徑全威力彈藥 空槍重6.8千克，歡迎閲讀。
在華盛頓特區舉辦的美國陸軍協會（AUSA）年會展覽會現場，MG 技術公司（MG Technologies）展出了一挺新型機槍。
這挺機槍是根據該公司與美國特種作戰司令部（SOCOM）籤署的合作研究與開發協定（CRADA）設計的 LMG-A-GP，作為改進現役 Mk48 機槍性能的演示原型槍。該槍配備速換槍管，槍管長度為 12.5 英寸（318mm）至 18 英寸（457mm）。當安裝 12.5 英寸槍管時，該槍重量為 6.8 千克。
美國特種部隊裝備的 Mk48 機槍是海軍特種作戰中心（NSWC）與比利時 FN 公司聯合研制的，将 5.56 × 45mm 口徑的 Mk46 機槍進行放大，成為 7.62 × 51mm 口徑的中型機槍，并取消了彈匣供彈和可調導氣箍功能。Mk48 機槍重 8.28 千克，盡管比 M240B 的 12.29 千克輕了 33%，但仍然沒有達到理想的目标，并且對射擊精度和使用壽命造成負面影響。
與 Mk48 一樣，這挺機槍口徑同樣為 7.62 × 51mm，但可以更換為 6.5 克裏德莫爾和 .300 BLK，這兩種口徑分别為美國特種作戰司令部小口徑狙擊彈藥和微聲彈藥。據稱内部有緩衝器，可以吸收連續後坐力，不會對機匣產生影響。推測因為機匣不會受到過多的力量，所以會采用較薄的鋼板制造，減輕了整體重量。
雖然它不是為美國特種作戰司令部目前推動的 " 輕機槍 - 突擊（LMG-A，Lightweight Machine Gun – Assault）" 計劃專門設計的，但它肯定會成為有力的競争者。LMG-A 計劃旨在取代美國特種作戰司令部現役的 Mk48 機槍，該計劃似乎仍在進行評估，仍有競争者出現。
這是 LMG-A 計劃的招标要求原文，有興趣的朋友可以自行了解。
The LMG-A shall be a lightweight belt fed, multi-caliber system which will include a primary barrel, spare barrel, with required bolts, barrels, and operating groups for each caliber, buttstock, receiver, sound/signature suppressor, operator manual, cleaning kit, operator tool kit, maintainer tool kit, spare parts kit, training munition kit, bipod, backup iron sights, sling, and a Transportation Security Administration ( TSA ) approved locking hard carrying case capable of storing a fully accessorized weapon.
The LMG-A will extend the range of suppressive fire capability out to 1500m. The LMG-A shall be accurate to 6.0 MOA ( T ) / 3.0 MOA ( O ) at 100 yards firing 7.62mm NATO ammunition and USSOCOM TDP 6.5CM ammunition. USSOCOM is also interested the capability of the LMG-A to adopt other calibers such as 6.8x51mm high pressure ammunition ( U.S. Army TDP ) and the .264 Lightweight Intermediate Caliber Cartridge ( .264 LICC ) via caliber conversion kits.
SOCOM has been interacting with industry for years discussing a 6.5 CM gun. During SHOT Show, 7.62 NATO entered the picture. I asked someone in industry why and was told that the answer is that there ’ s loads of 7.62 ammo available. ( Naturally, I immediately said, ".276 Pederson." ) Word is that the 6.5CM ammo programs aren ’ t progressing very quickly, so like with 300 BLK on RASR, they ’ re moving forward with an ammo supply they can rely on.
They are shooting for a gun which weighs, at its heaviest, 17 lbs. At that weight, it ’ s just a pound lighter than the Mk48 it ’ s replacing. The new gun has to handle 6.5CM which isn ’ t an issue but those other calibers could be tough for some guns, especially as you get down to the objective weight of 12.75 lbs which is around what the developmental model of the KAC LAMG in 6.5CM weighs.
The command has publicly released these additional requirements:
Operation and Performance characteristics
a ) The LMG-A shall be capable of firing in fully automatic and semi-automatic firing modes.
b ) The LMG-A shall have an ambidextrous safety selector that prevents the weapon from being fired when the trigger is depressed and the weapon is on SAFE ( T ) , capable of charging the weapon when the weapon is on SAFE ( O ) .
c ) The LMG-A shall be capable of firing 7.62x51mm NATO family of belted ammunition to include training munitions, and USSOCOM TDP 6.5 Creedmoor belted ammunition via left-hand feed.
d ) The LMG-A shall have AMR not to exceed 6.0 MOA ( T ) , 3.0 MOA ( O ) at 100 meters ( 109 yards ) when firing 7.62 NATO ammunition.
e ) The LMG-A shall be equipped with quick-change barrels in assault and standard configurations.
f ) The LMG-A shall be capable of being suppressed, while reducing the signature of the weapon in flash, ground disturbance, sound, and gas blowback. The suppressor shall not modify the rate of fire by more than 10% ( T ) or 2% ( O ) .
g ) The LMG-A suppressor shall be of a quick-detach, lockable design, and minimize Point of Aim/Point of Impact shift when mounted or dismounted.
h ) The LMG-A shall have a two-position, non-reciprocating charging handle that is operable and moveable to both the left and right-hand side of the weapon.
i ) The LMG-A shall have a user-adjustable bipod that is rapidly deployable/stowable and provides tension and lockup upon loading.
j ) The LMG-A buttstock shall have an adjustable for length ( T ) , collapsable ( T ) side folding ( O ) , and adjustable cheek riser ( O ) that does not interfere with the function of the weapon.
k ) The LMG-A shall have a maximum overall length with bipod attached, buttstock, and barrel ( with suppressor ) of 49.0 inches ( T ) less than or equal to 44.0 inches ( O ) . Sights and other accessories will not be included in the weight requirement.
l ) The LMG-A shall weigh no more than 17.0lbs ( T ) , 12.75lbs ( O ) .
m ) The LMG-A shall have Mil-STD-1913 rails, with numbered slots at the 12 o ’ clock position with a minimum of 8.50 inches aft of the feed tray cover for optical sights.
n ) LMG-A shall have M-LOK attachment points at the 3, 6, and 9 o ’ clock positions on the forward handguard to support the attachment of accessories and enablers.
o ) The LMG-A shall have a rate of fire between 500-750 rounds per minute ( T=O ) .
p ) The LMG-A shall minimize felt recoil across all firing modes.
q ) The LMG-A shall have a single mounting point for DoD-common weapons mounts.
r ) the LMG-A shall have a mounting point for common ammunition carrying boxes or soft pouches.
