B& amp； T MP9 tactical submachine gun

B& amp； T MP9 is Bourouga &; Submachine gun (assault pistol) designed and produced by Tome company. Among them, MP is written as "machine gun pistol" in English and "charge pistol" in Chinese. MP9 fires 9× 19mm pistol bullets.

by b & amp； The MP9 tactical submachine gun produced by T Company is the only tactical submachine gun designed for professionals. Because MP9 is improved from the original design of B& Stail B& Company; The T MP9 is also equipped with a forward-leaning front grip, which is similar in stability and accuracy to the TMP9.

The biggest difference between them is that MP9 is equipped with a stock that t MP doesn't have (the stock will fold to the right when folded) and a tactical guide rail of MIL-STD- 19 13, and accessories such as optical sight, red dot mirror/reflective sight, holographic sight or night vision device are directly installed at the top opening of the chassis (a section of guide rail can also be added at the front right side of the chassis to install artillery collection bags and tactics).

All parts of MP9 gun are integrated, and even with tactical accessories, its lines are still smooth. Made of new engineering plastics, it has strong corrosion resistance and will not rust even when used in seawater. Unlike other submachine guns, B&; T MP9 submachine gun can also be stored in its special leather case like a pistol. In order to facilitate users wearing ordinary casual clothes to carry in the car, shoulder-mounted holsters can be used to carry guns. In case of emergency, users can shoot quickly. When used by drivers of heavy vehicles (such as trucks), pilots of airplanes or operators of other instruments and equipment, MP9 is also carried by a holster hanging on the chest; In order to meet the needs of special forces, the manufacturer also provided a leather case hanging on the thigh, so that the MP9 can be hung on the user's thigh like a traditional pistol.

The design of MP9 takes ergonomics into full consideration, and its use mode is very simple. The gun has good quality and high precision, and can be used with one hand in an emergency. It was originally conceived as a personal defense weapon for unconventional combatants such as officers, artillery and train attendants.

MP9 is a weapon using the principle of short stroke recoil of barrel. It adopts a closed bolt, and the locking protrusion in the barrel can protrude heat dissipation, which is helpful to reduce the risk of spontaneous combustion of the barrel and improve the shooting accuracy of the gun.

MP9 adopts barrel rotation locking mode, which is very clean during use. The test shows that the gun does not need to be wiped after firing 6000 rounds, and there will be no fault. MP9 adopts translucent magazine made of high-strength polymer, so users can check the remaining ammunition in the magazine at any time. Its magazine capacity is 15, 20, 25 or 30 rounds respectively, and its weight is 240 g, 300 g, 370 g or 440 g respectively.

Unlike most other weapon systems, the firearms, ammunition and suppressor of MP9 are all developed by the same company. When its quick-release microphone is installed and equipped with subsonic ammunition, the muzzle noise can be reduced to below 32 decibels. B& amp； T Company claims that MP9 is suitable for any existing 9× 19mm Parabellum caliber pistol bullet in the world, and it has also developed its subsonic ammunition and muffler, which can effectively reduce the muzzle flame and noise when shooting, and also increase the user's concealment when using it at night or in buildings.

MP9' s sharp-edged ghost ring-shaped photo door helps users to prevent guns from being caught by clothes when hiding their guns. MIL-STD- 19 13 tactical guide rails are installed at the top of the chassis, which can be used to install accessories such as optical sights, reflective sights, night vision devices or thermal imagers. In addition, laser sights and tactical lights can be installed, and a section of guide rail can be added on the right side of the wooden guard plate for users to install shell-collecting bags and tactics.

MP9' s mechanical sight consists of a ghost ring door and a cylindrical sight, with adjustable height and direction. The aiming baseline length is 190mm (7.48 inches), and the three tenons of the muzzle can be equipped with a quick-release suppressor or flame arrester (and the bottom is integrated with MIL-STD- 19 13 tactical guide rail, and tactical lights or laser sights can be installed). You can also choose to use the general L-shaped butt stock and zigzag bent butt stock used by special police, aiming at shooting when wearing a helmet with a mask or bulletproof glass, and you can also add a shell-collecting bag to the shell-throwing opening on the right side of the chassis.

After inserting the magazine into the magazine slot and pulling the handle to load the bullet, the user does not need to do other shooting preparation actions before firing because there is no bolt safety mechanism on the gun. Like Glock pistol, MP9' s main insurance mechanism is trigger insurance, which can withstand a fairly high trigger pull and make the trigger unable to fire. For this trigger feature, ordinary users need to have a familiar process. Commandos or policemen who often practice live ammunition are fine, but they can be used as auxiliary insurance institutions. The second safety mechanism is a drop safety device arranged on the back of the watch case, which directly acts on the needle. Only when the user pulls the trigger can the fall insurance be released.

MP9 can shoot semi-automatically or fully automatically, and its reducer is located at the front end of the grip. Push the speed lever to the left and see a red dot, indicating the semi-automatic shooting position; Push to the right, and you will see three red dots, indicating the fully automatic shooting position. After the magazine is emptied, the bolt is in the rear position to hang the empty magazine. In fully automatic shooting, after the shooter shoots several bullets, the gun automatically stabilizes, which helps to hit the target accurately. In case of emergency, the shooter can hold MP9 with one hand like a pistol, and shoot semi-automatically or fully automatically, but the dispersion will be slightly larger. The Sling ring located in the middle of the back makes it comfortable and safe for the gunman to carry a gun. The user can hang the strap on his neck or shoulder, and the muzzle is always aimed at the target direction. In an emergency, the user can take off the gun belt and gun from his body in a few seconds and enter the fighting state.

The disadvantage of MP9 is that the gunpowder gas will escape from the gun after the shell is thrown and the handle is pulled, so the user needs to wear protective glasses. However, when the submachine gun is equipped with a microphone to fire, the powder residue will accumulate in the shell and need to be wiped frequently.
