The barrel should be detachable and quickly replaced without adjustment after replacement, and the time for replacing the barrel should not exceed 20 minutes. The total length of the system does not exceed 52 inches, but does not exceed 40 inches when the extension (such as muffler) is not included. The weight of the system includes 12 picatinny rail and 5 solid magazines, and it does not exceed 18 pounds. Regarding the most important shooting accuracy, it is required to fire 10 rounds whether shooting shoulder to shoulder or shooting on the bench with a fixture, and it can be kept at 1.0 MOA between 300 meters and 1500 meters. Finally, all bidders are required to submit 3 PSRs, 3 sights and 1 silencer, straps, disassembly/maintenance tools, 10 magazine, biped, carrying bag, gun box, operation manual and 2000 rounds of ammunition.
Competitors who have already participated in the bidding include Remington MSR, Barrett M98B, SACO TRG-42 of Finland, Blaser R93 of Siegel, AWM338 of British Precision International, ASW338 of Ashbury of the United States, AR30 of Amarette and PGM of Drake Industries of France. Remington ·MSR's full name is "Modular Sniper Rifle", which was first made public at the SHOT SHOW in 2009. Remington MPD lost to XM 1 10 of KAC when it participated in the US Army's SASS program last time. This time, the MSR developed by Remington Military Products Company (MPD) is considered as a promising candidate for PSR, because the modular design of Remington MSR is more flexible than other PSR candidates. At present, Remington has applied for a patent for MSR.
Although only manual or semi-automatic rifles are mentioned in the tender requirements, and the caliber is not specified, all bidders, including Remington MSR, submit the scheme of manual rifles with the caliber of 338LM, which obviously requires that1.500m should be kept at 1 MOA, so that no company dares to submit semi-automatic schemes. Although the current high-precision semi-automatic rifle can score 1 moa at close range, only the manual rifle can keep the requirements of 1 moa, 1 500m at medium and long range, so all bidders choose .338, so the manual rifle is the best choice.
In addition to the 338lm caliber used in PSR bidding, Remington MSR had two calibers when it was first introduced, namely, 300WM and 7.62x5 1mm NATO, and then the caliber of 338NM was added, which was a new caliber developed by Norma Ammunition Company of Sweden in 2008, and it was very close to 338lm..
