The first series of Pulse Rifle, the M41 was issued to Marines stationed on LV-429 during the events of the first Aliens vs Predator was accurate when fired in bursts but jammed frequently when fired fully automatically. It also features a retractable stock and an underslung four-round 30 mm PN grenade launcher. The Pulse rifle has a small battery-powered digital readout screen that displays the number of rounds left in the magazine, with the battery located in the grip. The magazines can hold 99 rounds, but were usually underloaded by 4-6 rounds capacity to avoid a spring-tension overfeed jam.

Made of light alloy plates, it fires 10x24mm Armor Piercing Caseless Rounds from a 100 round U-bend magazine in either semi automatic, four round burst, or fully automatic rates of fire. The M41A Pulse Rifle is an air cooled, fully automatic, short- to mid-range combat rifle.
