M9 bayonet is a multifunctional modern bayonet. It can be used not only as a bayonet and combat dagger for guns, but also as a field tool knife. M9 bayonet can be divided into handle, handle seat, handle core, cross guard, blade, scabbard, scabbard insert, grindstone, hanging belt, hook, etc. The dark green handle is made of ST80 1 nylon produced by DuPont. It is originally cylindrical, and its surface is engraved with reticular and annular grooves, which has good grip and sliding feel and excellent insulation performance. The scabbard is also made of ST80 1 nylon with high strength. The front is attached with a strip-shaped fiber bag, which can hold small items. There is a grindstone on the back, which is generally covered with fiber tape for protection. The bottom of the scabbard is a steel insert, which is fixed with the scabbard by hexagon socket head screws. There are bamboo shoots and cutting edges on the insert, and the cutting edge of the screw is at the top. The plug-in can be used as a screwdriver or bottle opener.
The blade body of M9 bayonet is made of forged stainless steel, which is threaded with the mandrel of the handle. The surface of the blade is light gray, and the cutting edge is extremely sharp after local heat treatment. The flat hole on the back of the knife is sleeved on the bamboo shoots on the scabbard and closely matched with it, and it can cut iron hoops or ribbed steel wire mesh with a diameter of 0.25in(6.35mm). The serrated teeth and file teeth on the back of the knife are hard and sharp, which can cut through the airplane shell, 2-inch (50.8 mm) thick pine boards and hard sticks with a diameter of 1 inch (25.4 mm).
When M9 bayonet is used as a gun bayonet, firstly, the muzzle ring on the bayonet cross guard plate is sleeved in the muzzle flame arrester, and then the bayonet seat of the gun is pulled back in place. There are two small clamping grooves on the handle base (the tail of the handle is connected with the handle core rod through screws), and there are two spring-loaded rotating bamboo shoots in the groove of the bayonet base, so that the bayonet and the gun can be combined in place. When pulling out the bayonet, hold the straight lines of bamboo shoots on both sides inward with your fingers to loosen the bamboo shoots, then move to the muzzle and take out the bayonet.
M9 bayonet is a new generation of multifunctional bayonet developed and assembled by the United States for NATO guns such as AR 15, G3, FNC and their variants after M7 bayonet. The M7 bayonet originally designed for AR 15 can't meet the needs of modern warfare because of its lack of innovation and universality. It is inevitable that M9 will take its place. But structurally, M9 is not the creation of Uncle Sam, but something borrowed, and its invention patent of "knife+sheath = scissors" structure should undoubtedly belong to the Soviet Union. When Red Army soldiers trained Kalashnikov's multi-purpose bayonet on the improved AK47 (the earliest AKM) in 1959, American soldiers were still using m 65438+ with M6 bayonet.
1986, the United States Army Equipment Command organized the selection of new bayonets. After fierce competition from six domestic and foreign manufacturers, the improved hunting knife of Phrobis Company of the United States finally won the first prize, and the military named it M9 multi-purpose bayonet system.
M9 can be said to be a replica of Kalashnikov multi-purpose bayonet equipped by AKM AKM AK74, but it surpasses similar Soviet products in technology, mechanics, ergonomics, aesthetics and many other aspects, making it unique and becoming a famous knife.
1September, 1989, Phrobis Ltd completed the first contract for M9 bayonets of the U.S. Army, with an output of 3 15600 bayonets. The knife marks of these bayonets are: M9 PHROBIS III PAT PEND, USA. There is a difference between a wide font and a narrow font. Contract bayonets are manufactured by BUCK Company authorized by Phrobis Ltd, and are characterized in that both the hand guard and the scabbard have dolphin symbols composed of PHORBIS letters, and the scabbard is a shoulder structure with an accessory bag and a sharpening stone. The scabbard and the handle are olive green, the blade is gray, the right side has a forged blood groove, and the hand guard has a bottle opener groove.
1In September, 1989, after completing the first contract for the M9 bayonet of the US Army, Phrobis III Company changed its name to Phrobis Int'l, and authorized Marto Company in Toledo, Spain to continue to produce its improved M9A 1 bayonet. Unfortunately, the improved M9A 1 bayonet was not adopted by the US Army. The blade of this knife is marked as: left M9 Phrobis Int'l U.S.A Right U.S. Patent No.4,821356, in which the number is the authorization number of this knife in the United States, and the hand guard has a dolphin logo and a bottle opening slot.
199 1 mid-term, Barker Company purchased part of the manufacturing rights of M9 bayonets from Phrobis Ltd to produce M9 bayonets with company logo for sale and export in the private market. It is characterized in that the whole body has no dolphin logo, and the structure is the same as that of Phrobis prototype M9, which is divided into green and gray knife fittings, the blade is divided into gray and black specifications, and the blade body logo is BUCK 188 USA. In the same year, the Austrian army chose Buck M9 bayonet with AUG rifle, and the blade was marked Buck 188↑ USA.
At the beginning of 1995, the US Army approved Lankai to continue to produce an improved M9 bayonet with novel design, instead of forging a blood groove on the upper surface of the blade, the hand guard did not mill the bottle cap groove, the scabbard was changed to a one-shoulder structure, and the accessory bag and grindstone were removed. In the same year, Lancay changed its company name to Lan-cay Inc, and the blade was marked as M9 LAN-CAY USA. There are brown (for general forces), black (for special forces), white (for snow fighting), brown (for desert fighting) and orange (for underwater blasting forces of various services). The M9 knife produced by our factory is made of 425M stainless steel, which is forged by melting hammer and then heat treated. It is the hardest M9 made in America.
2000: Ontario began to join the production ranks of M9 bayonets in the United States, producing only olive green and black M9 bayonets. Its blade body material is also made of 425M stainless steel, which is formed by constant pressure die and directly heat treated without melting and hammer forging. Its quality and durability are worse than M9 produced by LAN-CAY Lnc.
Tapco Company of the United States once ordered a batch of M9 sabers from Zhejiang Pioneer Machinery Factory under China North Industries Company, and the specifications imitated the earliest original M9 bayonets of Robis Company of the United States. Three types are derived: K 1 (broadsword type), K4 (broadsword type) and D80 (Rambo type). These M9 sabers are sold back to the United States, and also exported to many Asian countries equipped with AR 15 rifles or directly exported to M 16A 1-CQ rifles made in China.
