Following the landmark success of the "M28 MK2 "Hawker"", the NAF's top brass decided to entertain the Johnson Arms Companies ideas on a dedicated slug-firing model. As such, a fellow named "Ted Lewis" had been pushing the Companies R&D teams to develop a dedicated slug-rifle on the "Hawkers" frame. With Hawker himself okaying the project, the "M30 MK4 "Lewis"" was swiftly put into development. Within the year, the "Lewis" was completed, given a high-quality optic, a longer match-grade barrel and a foregrip to assist the shooter with sending it's deadly ten gauge serrated Tungsten carbide cored high-tensile steel slugs down range. Of course the slugs are jacketed with a copper/tin alloy allowing for greater density of the ammunition. It uses the same twenty round magazines of the MK2 and was called by many of the same troops who used the MK2 "By far one of the most comfortable shotguns I've ever fired.". After the siege of Torbruk it was given the nickname "Pinwheeler" due to the spinning or flipping motion caused by the concussive force of the self-rifling armor piercing slugs.
