Basic Information
The weapon uses a heavily modified TKB-022PM firing system, that does not require the complicated case ejector, as it fires caseless rounds. This improves reliability drastically, and allows the weapon to be much more compact while still retaining relativley high reliability.
The weapon uses a detachable polygonal 5 groove 1: 10 inch (254 mm) right hand turn cobalt-alloy "flow formed" barrel; the barrel is made of an alloy that contains more than 50 percent cobalt. The barrel is roughly 13% heavier than standard steel barrels, but is more erosion and corrosion-resistant and is designed to retain high strength during long-term exposure to high temperatures. Cobalt alloys are frequently used in the aerospace industry, such as the hot-gas section of turbine engines. A proof of concept M240 7.62mm x 51mm NATO barrel, in practice, had 24,000 rounds test-fired through it, causing it to reach temperatures of 1,100 degrees, without failure. A steel barrel would have failed under such treatment.
The barrel itself, combined with polygonal barrel rifling, in use with the MA5B is extremely durable, and has a minimum 30,000 round barrel life, although it is possible to extend this or get use out of the rifle after the minimum is reached. The barrels can come in different lengths, although it is generally 20 inches long.
The weapon is made from composites and polymers similar to the P90, to both reduce the cost and weight as of the weapon, as well increase the durability. The weapon fires from a closed bolt for both maximum accuracy and reliability.
Each barrel possess a muzzle break designed after the surefire muzzlebreak. The muzzle break is intended to reduce the recoil of the weapon from an already relatively low level to being nearly absent, although some recoil is always present. As well, the design of the weapon and it's straight back recoil impulse, as well as the tighter, more steady grip on the weapon, combined with the impact gel recoil pad, makes the weapon very easy to use and relatively comfortable.
In addition, the weapon is designed to be used with the XM25 airburst firing scope and platform, enabling the weapon to have an "integrated" airburst function. While the electronic equipment is not integrated, it can be added with relatively little ease, and be used much in the same way that it was designed to be used on the XM29. This also allows for grenades to be fired easier, as the firing controls are next to the trigger and pistol grip for ease of reach.
The weapon uses a Blackbox round counter that can be hooked up to an LCD screen to show the rounds remaining. The magazines are generally color coded, which provides indication of how many rounds are within each magazine, although loading in another magazine that does not meet the criteria can result inaccurate round counting predictions; the round counter mechanism itself, however, will not falter.
The weapon uses an extendable stock in a similar manner to sniper stocks. Despite being a bull-pup, several multiple point guiding stocks are used to allow the user to adjust the pull of the stock up to three inches. While extendable, the stock adjustments must be made by loosening and tightening multiple facets, making extending or retracting the stock take a relatively large amount of time.
While picanty rails are integrated into the weapon, many attachments are expected to be used with the weapon, regardless of the versatility of the system.
