Production Model Tennenbaum AMR. Details are sketchy, but they are believed to be based on, at least in appearance, on lengthened versions of 20th Century Scout rifles for ease of handling.

Based on the legendary Tennenbaum Devices issued to the Internal Security Bureau, the Tennenbaum Anti Materiel Rifle is a weapon meant to take on armored vehicles and exo suits, and to provide mobile support where needed.

The weapon itself can be fashioned from either present stocks, or made from scratch. Plans are in the works to convert surplus Colonial Scout Rifles into Tennenbaum AMRs. Additionally, specialized AMRs can be fashioned from existing bolt actions as well; Dr. Tennenbaum reportedly had success with Mosin Nagants and Lee Enfields.

The "scratch built" Tennenbaum AMR holds five rounds inside a detachable box magazine. Additionally, original Tennenbaum AMRs operate on a modified bolt action system, believed to be derived from Mauser actions, and are chambered in 8mm Mauser.

System functions similarly to the Mauser action. However, instead of a conventional firing pin, there is an electric charger. Here enters the round itself. The rounds themselves are made from a classified mixture of substances, most generally noxious and poisonous to humans and highly explosive and volatile when mishandled.

When the trigger is pulled, the electric charger sends a current into the round, beginning a violent chain reaction within the round itself. At the same time, a small bit of oxygenless propellant in the round forces the round forward, having been ignited by the current. Out of the barrel, the round flies towards its target, where upon impact the sudden jolt will cause a plasma jet penetration effect, with a small explosion on the outside and massive damage to the inside.

The Tennenbaum AMR served in limited conflicts, mostly with the Miradethian Campaign and in other sectors, as well as the Civil War, where it found its niche as both a tool for tearing apart armored vehicles as well as groups of infantry, in and outside of cover.

The most recent version of the Tennenbaum AMR is the NORINCO QBU-190 Designated Marksman's Rifle. The weapon itself was created as part of a post-Civil War search for the best possible upgrade for the venerable design, which demonstrated its usefulness, but at the cost of a slow rate of fire that made it a potential liability in defending against the massed attacks favored by the Mahdists.

Work by Gordie Zann's team at the NORINCO Special Projects Division in Hab 23 produced a design which was essentially a Tennenbaumized Zastava M76 Sniper rifle, chambered in an 8mm cartridge. Refined further from the original prototypes, the design was accepted along with upgraded rebuilds of the classic AMRs as the M19 and M20 respectively.

The QBU-190 is at its heart a Kalashnikov rotating bolt system, mated with the Tennenbaum-system's electrical firing mechanism. When the gun is fired, the electric striker charges the round and sends it flying out in the manner similar to to the classic tennenbaum system.

To accommodate the repeating AK mechanism, the bolt-carrier and piston assembly is modified, replaced with a kinetic feedback system that automatically recharges the electrical striker every time the rifle is fired; the Zann Feedback System attempts to reduce the amount of parts moving around in the system itself to reduce maintenance and help improve accuracy.

In addition, the rifle itself can accept bayonets, and has rails on it for all kinds of goodies.

The cartridge itself fires 8mm Mauser caliber Tennenbaum Improved Cartridges, which are not only designed to be more potent, but also, easier on the weapon itself.
