Heavy Stubber2
The standard LMG for the Lenehenese Imperial Guard, the Heavy Stubber is essentially a scaled-up version of the smaller Autogun (It's official name is the MK. XIV Infantry-Portable Heavy Autorifle), the name 'Stubber' is common slang amongst the Guard and refers to a wide variety of high-calibre slug throwers.  Firing heavy-calibre bullets able to stop a man dead in his tracks or chew through light armour, their use is limited to large formations of unarmoured or lightly-armoured targets. Weighing just under 5 kilos, with a length of 1.05m and an RPM of 850, the Heavy Stubber is ideal for providing fire support and is always assigned to at least one member of an  infantry squad.
