The M41 Pulse Rifle is an air cooled, electronic pulse action, selective-fire automatic rifle. The M41 is designed as a modular weapon that can fire the caseless M3xx family of 10mm x 24 high explosive light armor piercing rounds and high-velocity 30mm grenades.

Armat produce the M41 in three basic variants: the lightweight automatic assault rifle (with integral 30mm slide-action grenade launcher), the lightweight sniper rifle, and the heavy automatic battle rifle with unique high capacity L-shaped magazine. A universal T-bracket enables no-tools mounting of passive electro-optic, thermal imaging and laser rangefinding weapon sights to carry handle/sighting rail. It has been the standard longarm of the Colonial Marine Corps since the mid-60s.

In operation the Pulse Rifle operates on the electronic pulse action principle. The system uses a primer, electronically-fired at 17.5 volts. +/- 2 volts, the upper and lower limits preventing fire from either stray currents or static electricity. The direct electrical firing eliminates the mechanical delays associated with a striker and the possibility of jams with an extraction system, allowing for high sustained rates of fire. An LED counter on the reciever above the magazine well provides a visual record of rounds remaining. Electrical power for the rifle is provided by an internal Polymer Ion power cell which has a runtime life of 10,000 firings and can be recharged from the ports built into all rifle racks or weapon lockers.

The ammunition used is caseless i.e. without a cartridge case to contain the propellant. Instead, the projectile is encased in a solid molded block of Nitramine 50 (a nitrocelulose-based compound which is highly inert with a high ignition temperature to prevent cookoff), making it more compact that a full-length rifle round. This allows more ammunition to be carried for the same weight as conventional types, maximising logistics. Additionally, because the projectile doesn't have to be designed to fit a case (as the propellant telescopes around it), it can be of an aerodynamic shape optimised for its speed, accuracy and penetration.

To further reduce space and logistic loads the propellant block of the caseless round has a square base to fit the polygonal breech, chamber and barrel assemblies. This allows for tighter packing of ammunition in a box magazine, maximising the space used when compared to the gaps between cylindrical cartridges in a conventional magazine.

The stresses placed on the breach, chamber and barrel are much greater than seen with conventional cased gun types. As such, these components are made from steel coated with a layer of vapour-deposited carbon crystal, which both strengthens and acts as a heatsink.

An additional component to the M41A Pulse Rifle is the undermounted M92A PN Grenade Launcher, which is a
gas-operated, electronically primed, slide action repeating grenade launcher.
