Basic Information
The weapon is essentially magazine fed 7.62mm x 51mm Caseless weapon using a vertical bolt system styled after the TKB-022PM. Unlike the TKB-022PM, the weapon system is caseless, and doesn't require a complicated extractor in order to get rid of spent brass casings, significantly improving reliability of the weapon system by reducing the complexity of the parts. As well, the weapon replaces many of the high friction parts with aeronautics grade cobalt chrome, cheaply formed through flow forming and other similar techniques.
The weapon can sport a 45 or 60 round magazine, based off of the Ak-47 magazine design. While the Ak-47 magazines generally only could carry 30 or 40 rounds of 7.62mm x 39mm ammunition, the 7.62mm x 51mm NATO caseless rounds is roughly 50% lighter, allowing the same spring strength to load and fire more rounds without questionable reliability. The 7.62mm x 51mm caseless rounds also sport an enlarged base, to help with feeding.
The weapon fires from a closed bolt and due to the heat intensive hexagon binder, is unlikely to experience a cook off like in most caseless weapons- firing from a closed bolt also helps to increase reliability and first shot target acquisition.
The barrel is a 20 inch long polygonal cobalt chrome "flow formed" barrel with a 5 groove 5R (5 grooves, rounded) rifling twist of 1:11.25 (1 complete turn in 11.25 inches / 286 millimetres) , for both increased reliability, durability, accuracy, general performance, and rapid fire capability. 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 weapon sports a muzzle break and recoil buffer, and uses an impact gel pad in the stock to help mitigate felt recoil and to increase comfort.
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.
The weapon uses a FN herstal round counting blackbox and a HUD scope, capable of being integrated with the advanced land warrior system.
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 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.
