Like its larger brother the 'Kraus' combat pistol, the Rudd is a polymer encased asynchronous linear chem-rail pistol employed by the Colonial Pact as a issued sidearm for higher ranking officers and for issue to those that need a more concealable and lightweight sidearm. This very factor has also made it a popular item in the civil arms and private arms market as a concealed carry weapon.

As stated above the Rudd was designed as a concealable weapon based on the ALP-57U 'Kraus' pistol with its dimensions reduced. As with most size reduction projects certain compromises where made to performance in order to reduce the weapon's size. The largest being the simplification and reduction of the pistol's muzzle compensating device, effectively reducing it to a few forward oriented vents. While still functional the Rudd is far less controllable in automatic fire when compared to its larger brother. Additionally while the magazine size was retained the size of the power cell within was reduced, this was also accompanied by a reduction in barrel length and as such a reduced acceleration coil. While reducing weight and size it has also hampered the muzzle velocity when compared to the larger counterpart. However these compromises come with the bonus of having a still rather capable firearm that can be readily concealed on one's person.

Effectively a more compact twin to the Kraus, notable differences include the reduction in the size of the sights, a shorter overall length, the deletion of the forward rail, and a smaller sized grip. However it still shared the integrated frame charging handle, the jam extraction port on the right size of the pistol, and the same general display/trigger/firing selection group.

Below are listed and described the various mechanisms and interface systems of the Rudd compact chem-rail pistol system.

• Weapon Action Mechanism - The Rudd is a dual action weapon employing a electrically managed motorized blowback primary action and a secondary linear acceleration system to boost the weapon's muzzle velocity. It employs a closed cycle system using caseless ammunition, however in the event the weapon jams or needs to be unloaded a ejection port on the right side of the weapon can be opened and the action cycled. The action and rate of fire are handled by the weapon's computer system which actuates the action to be timed with when the linear acceleration system is active.
• Loading/Unloading Mechanism - The pistol feeds from a double stacked semi-motorized magazine, it is a drop free type meaning when the magazine release is pressed the magazine drops free of the weapon. When a new magazine is inserted the user must then pull back on a semi-integrated slide visible below the rear sights, this manually chambers a round, links the power system to the magazine's battery, and initiates the action mechanisms.
• Attachment Rails - A clamp style rail can be attached to the pistol's top to mount optics. However this is the only weapon mount option due to the pistol being designed for concealment rather then direct combat operations.
• SV90 Standard Lightweight Shielding - SV90 type applique is used on the inside of the pistol's frame to act as a dampener against exotic particles and waveforms which may damage the weapon's operating mechanisms.

• Firing Selector - The pistol employs an up or down ambidextrous selector switch which can be used to cycle through the various operating modes the weapon is capable of. Standard issue pistols of this type are setup as follows from bottom to top; safe, semi-automatic, burst, and finally fully automatic. However these can be programmed to user preference.

  • Contact Grip Safety
  • ID Grip
  • Mechanical Safety
• Magazine Release - The pistol employs a simple mechanical ambidextrous magazine catch just behind the trigger, when depressed the weapon disengages its ammunition/power magazine and drops it free of the pistol.
• Weapon Charging Mechanism - The charging mechanism employs a non reciprocating charging slide at the back of the pistol above the grip, when the magazine is inserted pulling this device will manually chamber a new round and initiate the power linkage between the pistol and the magazine's power cell. At this point the slide cannot be operated, primarily to prevent double feeding the weapon, however there is a ejection port on the right side that can be activated by depressing two buttons on the slide. Thus when pressed it allows the ejection port to open and ejects the chambered round, if the magazine is present it will chamber a new round.
• Sighting System - Red coated tritium nightsights of a triangular three dot style, additionally the weapon supports smart link optics and has the ability to provide augmented reality sights.
• Weapon Status Displays - There are three hardened weapon status displays on the pistol, a general one displaying weapon power status and remaining ammunition on both sides of the pistol above the trigger. The other being mounted on the rear sight displaying remaining ammunition and firing mode.
