The Precision Sniper Rifle (PSR) was a program by United States Special Operations Command to replace all current bolt-action sniper rifles in use by United States special operations snipers with a single bolt-action rifle chambered for a large caliber Magnum chambering like .300 Win Mag, and .338 Lapua Magnum. The solicitation was placed on January 15, 2009. The contract was awarded to Remington Arms for their Modular Sniper Rifle.
Sniper Rifle requirements included:
The system shall be chambered to safely fire factory produced "non-wildcat" Small Arms Ammunition Manufacturing Institute (SAAMI) or Commercial European standard (CIP) ammunition.
The action can be either manually or gas operated and available in left and right hand versions.
With primary day optic and ammunition the system shall provide 1.0 MOA from 300 to 1500 meters (in 300 meter increments) when fired from the shoulder or an accuracy fixture in nominal conditions.
This is further defined as 1 MOA Extreme Vertical Spread for all shots in a 10 round group at the stated distances.
Mean Rounds Between Failures (MRBF) shall be 1000 rounds.
The system shall have an overall length no greater than 52" in full configuration / extended excluding suppressor with a single component no greater in length than 40".
The system shall weigh no more than 18 lbs with a 12:00 MilStd 1913 rail and a loaded magazine with 5 rounds.
The system shall be capable of operator breakdown into major components in less than two minutes.
The system will assemble from the major component breakdown in less than two minutes by the operator.
The system will assemble from breakdown with no change in weapon zero.
The system will have an integral MilStd 1913 rail at the 12:00 position, the rail will be capable of maintaining bore sight alignment and weapon zero while conducting routine firing combined with combat movement and operational training drills.
Contenders for the contract included:
Accuracy International AX 338
ArmaLite AR-30
Barrett MRAD (Multi-Role Adaptive Design)[11]
Blaser Tactical 2
Desert Tactical Arms SRS
FN Ballista[12]
PGM 338
Remington Modular Sniper Rifle[13]
Sako TRG M10.
以上是霉菌招标的要求和几款参与投标的型号,我也看了一些视频,但是对于这些枪型是怎么实现快速更换和紧固管子那个地方我没明白,似乎除了AI家的之外都是采用了extension barrel 的结构。
版上应该也有大佬买了以上某款的枪吧,能否告知一些呢?
