The M41A E2 Heavy Pulse Rifle is a weapon used by the Colonial Marines as a squad heavy automatic weapon, designed to enhance the firepower of rifle teams.
Currently being introduced on a trial basis to selected rifle and recon platoons. The 'E2' is similar to a standard Pulse Rifle except that the grenade launcher has been removed and the gun modified with a replaceable barrel.
This barrel is 8 centimetres longer to increase the operating forces on the round and the barrel shroud has been extended to provide a solid mount for a folding bipod. An optional 'L' feed ammunition clip contains up to 300 rounds. The intention is to introduce the E2 as a light support weapon, the replaceable barrel offering greater rates of sustained fire in support of rifle and recon squads.
