The MT-22 Astute submachine gun (SMG) was developed as a personal defense weapon for the troops whose primary activities does not include small arms, such as vehicle and tank crew members, artillery crews etc. To achieve necessary high penetration while keeping recoil impulse low, the Astute fires from a closed bolt for maximum accuracy, and its design makes extensive use of polymers and nano-titanium for reduced weight and cost. The MT-22 is fully ambidextrous, it can be operated by right or left-handed shooters with equal ease, and without making any modifications to the weapon. the charging handle, magazine release, and the firing selector are symmetrically distributed on both sides of the weapon.
When fired, the MT-22 ejects spent cartridge casings downward through a chute located behind the grip, so spent cases are kept out of the shooter's line of sight. It can be fitted with a sling for greater ease of carry, and since the weapon has a fixed stock (as opposed to having a collapsing or folding stock), it can be quickly deployed when needed. A hollow compartment inside the rear of the weapon's frame which is accessed by removing the buttplate allows for convenient storage of a cleaning kit. The MT-22's grip safety uses a unique internal mechanism inside the pistol grip, which makes pressing it, light, smooth, and crisp.
Unlike its prototype the ASI-91 Asinine, the MT-22 is fitted with additional build-in front grip, improve flash hider and slightly extended front barrel. And instead of using a 50-round box magazine it uses a 20-round box magazine making it's overall length much shorter then that of the ASI-91 which was uncomfortable and difficult to handle because of its impractical long fixed stock which at the time was using a 50-round box magazine.
This problem became quite apparent during its field test firing phase, when many of the soldiers who were testing the weapon hated it and complain about how uncomfortable it was to used and fire along with other problems with it. Eventually leading to its complete redesign, the MT-22 Astute allow it to be easily carried and maneuvered in tight spaces, such as the inside of an armored vehicle. To achieve this, the weapon's design utilizes the bullpup configuration, in which the action and magazine are located behind the trigger and alongside the shooter's face so that there is no wasted space in the stock. The MT-22 requires minimal maintenance, and it can be disassembled quickly and easily. It is a modular firearm, consisting of four main component groups: the barrel, the moving parts group, the frame and trigger group, and the hammer group.
