Fetishism has gradually become the mainstream of light weapons in western countries.

Adoption has gradually become the mainstream of light weapons in western countries.

After trying out and evaluating a variety of personal defense weapons (compact submachine guns), the US Air Force finally made a somewhat unexpected decision: to buy a foldable barrel accessory for civil rifles, and use this accessory to modify the existing GAU-5A assault rifle of the Air Force, and use it as the next generation of self-defense firearms for front-line pilots of the Air Force, officially named ASDW self-defense rifle.

As for the well-known "celebrities" such as MP7 submachine gun of HK company in Germany, P90 submachine gun of FN company in Belgium and TMP submachine gun of Steyr company in Austria, they were unexpectedly not selected.

Prior to this, the self-defense weapon of the front-line pilots of the US Air Force was only a 9 mm or 0.45 inch (1 1.43 mm) military pistol, and their firepower was obviously weak in the face of emergencies.

Of course, this is not because the US Air Force is stingy or outdated, but because the size of the life-saving bag used for the ejection seat of air force pilots is limited, only 65,438+05 inches (40 cm) square and 3.5 inches (9 cm) high, so it is difficult for ordinary light weapons to fit into this life-saving bag.

ASDW self-defense rifle: civilian accessories bring "second life" to military guns. In fact, as a "supporting role" in this procurement case, the GAU-5A assault rifle is also a famous gun with excellent design. Its army code is XM-177-a name as inconspicuous as the air force code.

However, they all have the same name in the naming standard of Colt Company, that is, Colt car-15, which played a great role in the Vietnam War, and the world-famous M4 carbine also has endless karma with it.

Because of its excellent performance and small size (the size and firepower of submachine guns were better than those of submachine guns at that time), the US Air Force also purchased thousands of CAR- 15, that is, GAU-5A, for air force special forces and bases.

However, the fly in the ointment is that CAR- 15 still exceeds the size of the life-saving bag even if its butt is removed and converted into a so-called "life-saving rifle", so it is not put into the ejection seat to become a "self-defense rifle".

However, a modified civil rifle rewrites the "old yellow calendar" of the traditional ar rifle: the barrel quick disassembly kit developed by Cry-ha Catastrophe Tactical Company can simply disassemble the barrel into two parts or reassemble it, and the whole process only needs to open or close a few buckles, just like opening or folding a folding bicycle.

Most importantly, this modified barrel does not need to "gut" the existing AR rifle, but only needs to replace the upper shell and barrel part as a whole, which means that the US Air Force can still keep the lower shell of the original GAU-5A, thus saving the replacement cost to the maximum extent.

In addition, the U.S. Air Force also replaced the FAB defense company's foldable fit grip for ASDW self-defense rifle, replacing the original grip of GAU-5A, which is also a mature and cheap civilian product.

Therefore, it is easy for us to draw a conclusion that GAU-5A, who has served in the equipment sequence of the US Air Force for more than 40 years, obtained the "clavicle magic" by relying on civilian accessories. After folding, it can also bring three magazines into the pilot's life-saving bag, which opens the second life cycle of his service career.

Guide rails, grips and various small parts: civil products are military compasses. Undoubtedly, in the 1990s and earlier Cold War, no matter in the West or the East, the design and improvement of light weapons were all around the needs of the army and the police-for example, ACOG sight (the "four-sided mirror" in the game of "eat chicken"), red dot sight and picatinny rail, which have been popular for decades, were all designed and produced for the needs of the army, and the accessories of the US Army or special forces were first equipped.

These accessories can either greatly promote the improvement of firearms ergonomics (picatinny rail), or can achieve incredible binocular rapid zoom-in aiming, and at the same time see the panoramic image and zoom-in image of the target aiming (ACOG advanced optical sight), which is immeasurable for light weapons.

With the development of finishing and computer graphics, the design steps of gun accessories become lower. In countries that legally own guns, there are many examples of enthusiasts using CNC machine tools to independently design and process accessories at home. And these accessories, which were born for convenience and comfort, were finally commercialized and applied to the civilian market.

To put it simply, with the successful pioneer Picatinny track, as long as the installation bayonet standard is followed, all kinds of strange civil accessories can be installed to play its role. Obviously, the feedback from the market is faster than that from the military and the police.

It took Picatinny Railway Company 20 years from the concept formation to the appearance of finished products, while M-LOK and keymod, successors of Picatinny Railway Company, only took a few years to rewrite the guide rail map of civil firearms market.

At the Satolli Defense Exhibition, we can also see the subsequent development of American firearms-the M-LOK guide rail system has been applied to the M 1 10 sniper rifle of the Marine Corps, which is enough to show what role the civilian market has played in military light weapons.
