Autogun - Known Imperial Patterns: Agripinaa Pattern Type II - A pattern of Autogun hailing from the Forge World of Agripinaa, this Autogun is chambered for the largest standard ballistic round in the Imperium, and possesses a simple fire selector allowing the user to fire single shots, three round bursts or fully automatic streams. The oversized rounds this weapon fires gives the model an excessive recoil and muzzle flash, but also excellent damage capabilities. To compensate for its recoil, the barrel has had a counter-weight added to try to counteract the weapon's tendency to rise off-target during automatic fire.Agripinaa Pattern Type III - Another pattern of Autogun hailing from the Agripinaa Forge World, the Type III is a slightly reworked version of the Type II intended to speed up production. It fires a long 8.25 calibre round, on either single shot, semi-automatic and fully automatic, with a cyclic rate of fire of 650 rounds per minute with a muzzle velocity of 820 metres per second. It takes both a 20 and 30 round box magazine. This pattern includes a flash suppressor, but one of the weapon's drawbacks it is excessive muzzle flash on firing. There is also excessive recoil when firing the weapon in fully automatic mode due to the size of the round being fired, making fully automatic firing wildly inaccurate at standard combat ranges. The Type III version attempted to correct this by the addition of a counter-weight, a heavy block placed at the front of the fore grip, designed to reduce the weapon's natural tendency to rise off target during automatic fire, thus assisting the firer in keeping the target in his sights. While testing confirmed the counter-weight did aid accuracy, it also added to the weapon's considerable weight. This gun only includes a basic iron sight.Armageddon Pattern - Produced on the Hive World of Armageddon, the Armageddon Pattern is an old but proven pattern Autogun that is loud, lethal and uncomplicated; a heavy-hitter for an Autogun, it fires large calibre solid slugs from a 15-round short box magazine and can stand a phenomenal amount of abuse and keep firing. The Armageddon Pattern has become a staple of the arms trade in many sectors where there are uprisings as well as making inroads into frontier areas where its stopping power and robust design rapidly gains converts.M40 Armageddon Pattern - This pattern of Autogun is also produced on Armageddon, and is regularly issued to local Planetary Defence Forces and militia forces. Lightweight in comparison to other models, it only sports a 12-shot magazine.Hax-Orthlack Creed-9 Pattern - The Creed-9 is a compact Autogun designed for close-quarter warfare and constructed to a local variant of a long established design intended for Imperial Navy boarding troopers. Made using lightweight materials and fitted with a telescopic stock, the Creed-9 is not much larger than a military Autopistol in size and is the favoured weapon for many enforcer kill squads, as well as the private armies of numerous noble houses and Chartist Captains. Because of this "elite" role, it's common to see Creeds sporting numerous upgrades and modifications such as red-dot sights, expanded mag-ports and fire selectors.Urdesh Minor U90 Pattern - The U90 is a heavy duty Autogun of ancient design still manufactured on the Forge World of Urdesh Minor in the Segmentum Pacificus. Despite its retractable metal stock, the U90 is a long, cumbersome weapon. Its muzzle is unusually large to accommodate the weapon's .45 calibre rounds. This has led several Guardsmen to jokingly remark that the U90 is closer to a down-scaled Autocannon than it is to a true Autogun. The U90 offers phenomenal damage and can be fitted with several types of ammunition, including armour-piercing rounds. Standard ammunition clips used by the weapon include both the sickle-shaped 15-round magazine and the larger, 40-round drum magazines. The U90 can fire in both semi-automatic and full automatic modes. As a matter of tradition, every Urdeshi regiment carries an extensive stock of U90s as back-up weapons, which has proven its efficacy against the xenos mercenaries known as Loxatl. The U90's main drawback is that it is prone to jamming, especially with the larger magazines, but it is a risk many Urdeshi gladly take for the added firepower. As Urdesh Minor was occupied for many standard years by the Blood Pact, it is not unusual to discover the U90 in the hands of Chaos Cultists and Traitor Guardsmen within the sector of the Sabbat Worlds.
