The barrel of the Lucius is its most distinctive feature it has a series of heatsinks to dissipate the excessive heat buildup the increased energy output of the Lucius Pattern creates under sustained fire.
It was judged by the Kriegers that the extra stopping power of the Lucius pattern essentially makes up for this drawback. Another downside: Unlike other Lasguns, the Lucius is semi-automatic only, with a slower recycle rate than other Lasguns. This gives the weapon more punch, but drains the powerpack after only 25 shots. Made famous by the Death Korps of Krieg, the Lucius Pattern - sometimes called the Number 98 (unsubtle reference when one remembers what the Krieg look like) - is designed for brute force its power pack operates at a higher charge than many other more common patterns of Lasgun.Uniquely, the Voss operates only on automatic. Like the Galaxy Pattern, it's primarily seen used by the Armageddon Steel Legion and Catachan Jungle Fighters, being the favored Lasgun of the former. With all the firepower of its big brother but a shorter effective range, the Voss Pattern is essentially a Galaxy Pattern with a shortened barrel and a folding skeletal stock. The Voss Pattern is virtually identical to the Galaxy Pattern, and was intended for Chimera and Leman Russ Battle Tank crews - Guardsmen who had need of ample firepower but need to minimize both size and weight.The Galaxy Pattern was the first Lasgun in the Imperium to include an easily swapped barrel, enabling it to be easily converted to a Sniper Rifle (long-las) or cut down carbine (Voss Pattern). It lacks the standard bayonet lugs of the Kantreal Pattern (its immediate predecessor), but is both lighter, easier to handle, and still boasts a scope rail. Favored by the Catachan Jungle Fighters and the Armageddon Steel Legion for roughly the same reason, and being the preferred weapon of the former, the Galaxy Pattern Lasgun features a shorter barrel and increased cooling.Like the shorter Armageddon pattern, the Kantrael Pattern features a top-mounted rail to allow easy mounting of scopes and other accessories as well. The Kantrael Pattern Lasgun was developed specifically for the Cadian Shock Troops and for Kantrael's own PDF, and it shows the gun has a reinforced frame and was the first Lasgun to feature bayonet lugs as a built-in component. Named for the forgeworld in which it was first built, the Kantrael-pattern Lasgun is considered by many to be the most iconic Lasgun in the Imperium, with its only real rival being the Mars Pattern.In a brief effort to cover the dizzying number of different Lasgun types and a bit of information about each, this article has been made. There are a dizzying number of different Lasguns in the Imperium of Man, often referred to as "Patterns" (an old British terminology for firearm designs, in the 18th century the standard long arm of the British Army was the Land Pattern Musket), as many of them are made from specific design philosophies. The closest thing to choice an Imperial guardsmen will have - what sort of lasgun he'll get (not an actual choice, generally speaking).
