4 Minute Read

How much do you know about the weapon that TRULY holds up the Imperium – the Las-gun of the Astra Militarum?
lore via Lexicanum


Lasguns are reliable, easy to maintain and produce, and are readily available on most Imperial worlds. They have longer range and higher ammunition capacity than a Laspistol (the laspistol power packs having roughly 80 shots before depletion, compared to roughly 150 shots for a lasgun), but are nowhere near as powerful as a Lascannon. They also lack the rapid-fire quality of the Multi-laser or the Hellgun.
The lasgun uses the same basic technology and operates along the same lines as other laser weapons, emitting a beam of focused light. The high amount of energy in the beam causes the immediate surface area of a target to be vaporized in a small explosion. It is a relatively unimpressive weapon when compared to other weapons in the Imperium, but is still capable of cleanly severing limbs or piercing the power armour of a Space Marine (but only through a vulnerable spot in the armour). Most designs have iron sights mounted along the top of the weapon. It is powered by a small, rechargeable power pack located beneath the weapon, in front of the trigger guard. The pack can be recharged in many ways, including sunlight. It can also be “overcharged,” a trick used by Guard veterans that causes the pack to explode, turning the weapon into a makeshift grenade. This tactic is only used in last-ditch situations, as it results in the destruction of the weapon. The resultant explosion, however, is powerful enough to crack open the frontal armor of a Chaos Dreadnought. Lasguns have several lethality settings that adjust the damage of each shot in order to conserve power (weaker settings use less energy) or disable rather than kill a target. The weapon can also be fitted with a “Hotshot” pack, providing more powerful but less numerous shots.

Merovech pattern assault lasgun

Merovech pattern assault lasgun is designed purely for close range assaults. It is heavily reinforced and has a bayonet built into its short and heavy frame. Slots for two power packs are included so the gun can switch to a fresh pack with no reloading. Since the firefights it’s designed for are typically over long before two packs are exhausted, it serves its design perfectly.
