M41A "Pulse Rifle"
The M41 uses electrically-fired 10x24-mm explosive-tipped caseless ammunition, which can be selected to fire semi-automatically, in four-round bursts, or fully automatically. An underslung, hand-loaded, 30-mm pump action grenade launcher features a four-round magazine. The compact ammunition magazine holds 99 rounds, though is usually loaded with 95 to avoid jamming. An LED counter display located just below the receiver indicates the amount of remaining ammunition.
The M41 is constructed from lightweight, impact resistant composite materials, and weighs 10.8 pounds fully loaded. With shoulder stock extended, it measures 33.01 inches in length. Fully automatic rate-of-fire is 900 RPM, or 700 RPM effectively. By 2179, this weapon was the primary longarm of the USCM infantry.
