While many of the military fans have only seen the heavy-handedness of military guns, few know that a gun coming out of the factory production line to obtain military certification and official equipment is not easy to shoot with a few rounds. It is going through not routine tests, but near-pervasive maximum destruction and hell-class tests, cold heat, soil and water, wrestling, shooting and crushing, and dozens of harsh and harsh checkpoints that can't pass, with a direct payback and no right to go to war. As a military blogger, i would like to talk to you about how much of a qualified military gun would have to endure the unimaginable torture of ordinary people, using both domestic and foreign military gun stereotyping standards, real measurement processes and hard nuclear data。
The first is the all-encompassing torture of extreme weather conditions, which is a hard threshold for civilian and police guns. Regular military weapons must be subjected to high-temperature cycle testing, and the whole machine must be placed in a professional heating module, first frozen for several decades in a very cold environment of below 40 degrees celsius, with metal components completely frozen, lubricated and frozen, then removed without any reheating treatment, and immediately loaded with live ammunition, requiring a full-scale shell, non-frozen machinery, fractured needles, and targeting institutions. It will be followed by high temperatures of 70 degrees celsius, simulations of hot desert suns, high temperatures inside closed combat vehicles, non-soft plastic parts after long periods of drying, non-heated metal, and regular blasting. In addition to temperature, there are saline corrosive tests, simulations of the operational environment of coastal islands and high-moisture jungles, hundreds of hours of saline spray, no visible rust in gun-body steel, springs, aircraft cartridges, and no rusty carding of internal parts, which is why special nitrogen seepage and roasted blue preservative treatment of the surfaces of military weapons is used. The sand and dust tests are even more stringent, with high-pressure wind and sand currents continuing to pour sand into the barrel, inside the receiver, and even burying the whole gun in a small sand station, leaving it undisturbed, uncleaned, and firing directly with ammunition. Many civilian toy guns and sports guns cannot be cut off as a result of a shell failure in the sand, and placed in military tests. There are also showers and water bathing tests, simulations of storming forces, river crossing, high-pressure rain flushing the whole body of the gun, and even the full immersion of the gun into the water, which can be used properly after a few drops, and electrical circuits and blast structures that are completely free of water vapours, all of which are the basis tests for military designs。

Having survived climate violence, the next is the unreserved physical violence, which is a complete simulation of the real scene of battlefield bumps, falls and accidental impacts. The drop test is strictly standard and the whole gun is at a standard altitude of 1. 5 metres. It falls freely on the concrete floor, on the hard side of the rock, from the point of view of the gun, from the point of view of the barrel, from the side of the butt, from the angle of the rifle, from the point of view of the gun, from the point of view of the gun, from the point of view of the point of view, from the point of view of the gun, from the side of the rifle, from the angle of the gun, from the angle of the gun, from the side of the side, from the angle of the side, from the angle of the side, from the angle of the gun, from the point of view of the gun, from the point of view of the gun, from the point of the point of view of the gun, from the point of the point of view of the wall, from the point of the surface of the wall, from the point of the point of the wall, from which the bullet cannot break itself, and from the point of fire, from the point of the fire, from which it can be shot normally at any time. In addition to wrestling, vehicle crushing tests are conducted, with military light land cruiser vehicles running low through the body of the gun, which can be slightly deformed, but the core receivers and barrels cannot be broken and still have basic operational capability. There is also a long-term vibrating spiral test, where guns are fixed to simulated armoured vehicles, military trucks ' vibrating platforms, with high frequency swings for dozens of hours, a simulation of the continuous vibrations of long-distance marches, requiring internal parts not to be loosed, the targeting baseline not to be deflected, the re-entry structure not to be exhausted, and the loss of spare parts and the mistargeting of travelling vehicles. These violent tests are not half-watered, completely recapitulating the worst surprises on the battlefield, and are not worthy of being a soldier's side weapon。
After physical destruction, the most important test of the core quality of the weapon is the test of the maximum durability of the weapon, which is the hard link of reliability and barrel life, and the data standards must not be ambiguous. When military-type rifles are shaped, it is required that more than 5,000 undismantled, uncleaned and unwieldy live rounds be continuously fired, that the number of malfunctions be recorded throughout the course and that the average failure rate be kept within five per 1,000 to achieve the standard; the pistol standard is equally strict, with no major malfunctions in the tens of thousands of consecutive rounds of fire, and that the pattern is passed. Like our national 92nd pistol, 95th automatic rifle, and the glock, ak series of classic military guns, all go through a thousand durable tests, with barrel rifles with a life of more than 15,000 rounds, military pistols with not less than 20,000 rounds, until the barrel is naturally worn, ballistic precision begins to decline, thus verifying the quality and overall structural life of the barrel steel. The testing process also involves the deliberate use of different batches of manufactured munitions, the simulation of differences in field logistics munitions, the non-loading of firearms and the failure of ammunition to deliver as a result of its official service, and the stabilization of the blast, regardless of its quality. High-intensity continuous firing will keep the barrel hot and hot, and will also test the thermal insulation of the wood, thermal deformation of the receiver, and eliminate the danger of continuous fire over the heat chamber and the softening of the parts。
There are also violent operational tests that many do not know, which are designed to simulate the real scenes of the battlefield soldiers ' panic and irregularity. Testers will deliberately pull violent cartridges, force the break-in of the safety switch, break the gun handle, wear tactical gloves and even gas masks to operate the weapon, testing the design and structural tolerance of the machine gun, even if the method of operation is irregular, and will not allow for the death of the vehicle and accidental discharge. At the same time, a drop-off insurance test is being carried out, the gun is loaded and ready to fall, and it is dependent on self-armed needles and drop-back insurance that must be carried out in a way that will ensure the safety of soldiers as they march and climb. In addition, there are long-term strategic containment tests, which, after specialized rustproof sealing, have been in constant and wet storage for decades, which have been unsealed with simple cleaning and maintenance, and which continue to meet military standards and to be ready for operational use, which is also the test for which the national strategic stockpile must pass。

Many people tend to think that military guns are less sophisticated than competitive guns and are less expensive than collectors, which is why military guns are not designed to be highly sophisticated and attractive, giving priority to durable, reliable and resistant. The gun is delicate and sophisticated, with a small amount of sand, a bump, a low-temperature environment that can easily strike, can only be used in a hot and wet range and cannot withstand the military hell-like torture. A qualified military gun, after having survived cold, high temperature, salt fog, sand dust, water bathing, wrestling, crushing, tens of thousands of bursts of fire and the rough operation of dozens of checkpoints, is the only reliable equipment that can carry soldiers ' lives。
At the end of the day, each of the military guns we see is as simple as it looks, and the process is even a little rough, and behind them are hard currency that has been filtered through countless extremes. War environments are never mild, and wind and sand, severe cold, bumping, high-intensity use is normal. Only through all harsh tests, carrying the most extreme destruction, can the trigger be pulled unheeded and chained at a critical time. That is the difference between military weapons and ordinary civilian guns, the nature of police guns, and the root cause of its credibility。
