Brother One Who Understands gun emperor is the official account of the light martial arts column of the military sub-face public number, focusing on light weapons and striving for interesting and informative!
In the game "Crossfire", there is a rifle called the ancient artifact called 9a91, although the magazine capacity is only 20 rounds, but the recoil is extremely low and the lethality is also quite good, in the short and medium distance of the fire can be called strong and invincible, a point shot can basically headshot or take away the enemy.

In the real world, the 9a91 does live up to this false name, is a very cost-effective cqb weapon, the 9mm subsonic armor piercing bullet fired with the silencer is not only extremely quiet when launched, but also can easily penetrate the "tertiary armor"!

In the 1980s, on the eve of the collapse of the Soviet Union, frequent ethnic conflicts and political upheavals played out in the interior of this vast empire. To this end, the Central Institute of Precision Mechanical Engineering, in response to the kgB's 9th request, developed an easy-to-conceal SR-3 small assault rifle to equip the action team responsible for protecting key personnel.
However, in the actual use process, some elite anti-terrorist units equipped with SR-3 feel that this lightweight and small (SR-3 empty gun weighs only 2kg) and has stopped working well is simply a prodigy for the development of CQB! However, there must be some gains, because the design goal of the sr-3 is to be hidden and easy to carry, so the protruding pull handle was changed to a two-sided slider, and there was no sight mount on the side, and even any type of silencer could not be installed.
At this point, the elite Maozi helplessly issued a "lament" of regret: It's a pity!
▲ The SR-3 rifle is very easy to conceal and carry
The lament reached the Instrument Design Bureau in Tula, where they resolutely began to self-finance the "entrepreneurship" even when they discovered the business opportunities contained in it, and soon launched the 9a91 small assault rifle that fired 9×39mm subsonic armor-piercing shells and was more suitable for cqb operations, and began small batch production at the Tula Arsenal in 1994.
The big sale of the 9A91 prompted the SR-3 to also launch the corresponding CQB version of the SR-3M
The 9a91 rifle uses a long-stroke piston with a gas-conducted type that drives a rotary gun mechanism with four locking protrusions into an automatic loop. Without the magazine, the full gun weighs only 1.75kg, which is about 0.8kg lighter than the aks-74U. Like other 9mm assault rifles in the former Soviet Union (e.g., as, vss), the 9a91 can fire 9×39mm sp-6 subsonic armor-piercing bullets, which are enough to penetrate 8mm steel plates at a distance of 100 meters and Russian standard Class 3 body armor at a distance of 400 meters. A 9a91 with a 20-round capacity in-line magazine can also be paired with a silencer, which is sufficient to meet the operational requirements of the Special Forces CQB.

After the first batch of manufactured 9a91s was delivered to MVD for trial in 1994, the Instrument Design Bureau made improvements in 1995 based on troop recommendations, and the improved 9a91 had a quick-removable silencer.

There is also a mount mounted with an optical sight on the left side of the receiver, which can be equipped with a red dot sight for use as a cqb. However, it is also inconvenient to move the fast and slow machine that was originally located on the left side of the receiver to the right side of the receiver, and it is no longer possible to use the thumb of the right hand to operate quickly.

It is worth mentioning that after the success of the 9a91, the Central Institute of Precision Mechanical Engineering has improved the original SR-3 rifle in order to regain market share again, and launched the SR-3M assault rifle suitable for CQB operations, which also has the function of quickly disassembling the silencer and installing the optical sight, and the performance is particularly excellent.

But Omon (Special Purpose Mobile Force) and Sobr (Rapid Emergency Response Force), as well as some law enforcement agencies, have purchased 9a91. Because the receiver of the 9a91 is stamped and the production line of the AK rifle is used, the price is much lower than that of the SR-3. The Instrument Design Bureau even designed a cheaper PAB-9 armor-piercing shell for the 9A91 to replace the more expensive SP-6 armor-piercing shell at the time.

Like the ass special assault rifle of the year, the Instrument Design Bureau also launched the corresponding silenced sniper rifle vsk-94 based on the 9A91. The main part of the vsk-94 is actually the higher precision 9a91 rifle, which is simply replaced with a mechanical sight and a pso-1 sight, stock and grip become an integrated frame polymer. Despite the poor accuracy (2-4 moa within 400 meters), excellent silencer is his real strength, and the lower price also allows some agencies with limited budget to replace the VSS sniper rifle with the VSK-94. Naturally, when long-range precision shooting is required, the SVD sniper rifle is the first choice.

When the "self-funded" instrument design bureau earned the first pot of gold through the 9a91, they naturally began to plan to further expand the market on this basis, such as launching a variety of caliber 9a91 rifles, including 7.62×39mm, 5.45×39mm, 5.56×45mm three common calibers, but in the end they all disappeared.

However, in addition to this, the 9A91 rifle also has a more interesting no-support variant, the A-91M, and has received a small number of orders.
The structural principle of the A-91M is the same as that of the 9a91, but the gun body is made of polymer and changed to a supportless structure, initially only firing 7.62×39mm M43 bullets and using the standard ak magazine, and the fast and slow machine operating lever is also similar to the ak rifle on the right side of the receiver. The pull handle is located under the handlebar, which not only has a bore door but also a rail for mounting an optical sight.
▲ 9a91's stockless type - A-91M rifle
Careful friends may have found that there is no ejection window on the receiver of the A-91m, and this is the solution designed to solve the inherent defects of the no-stock rifle, in order to prevent the aless rifle from throwing the shell when changing the left and right hands, the problem of easy to "punch the face" and the gunpowder smoke "hot eyes", the a-91m rifle throws the shell shell through the shell tube from the front grip.
In addition, the A-91m incorporated a 40mm front-loading grenade launcher at the front of the gun body, initially fixing it above the barrel in its design prototype and adding a small grip and trigger at its lower end to control the launch of the grenade. However, in the finalized A-91m, the small grip design was abolished, and the grenade launcher was integrated under the barrel, while the launcher also doubled as the front handguard for the gun. The two triggers that control the rifle and the grenade launcher are also integrated in a trigger guard, the trigger in the rear controls the rifle system to fire, and the trigger in the front fires the grenade.
▲ After the stereotyped A-91M rifle, the grenade launcher was integrated below
It can be seen that 9a91 can be described as a very cost-effective cqb weapon, but if its no-to modify a-91m also appears in the game, I don't know what it will be like.
