Karta
Features three barrels and 4mm caliber for insane rates of fire without much recoil.
Fire modes: full auto, fuller auto, mega auto
600 RPM, 1800 RPM, 2400 RPM respectively
Fed by quadstack mag of 4mm rounds equipped with matter reconstructor which rebuilds 4mm ammunition fron inserted solids. Organics yield more rounds per volume of matter. Can be "fed" blood for round regeneration, creating new rounds while firing. Mag houses 400 bullets.
Damage in Construct: 10x5/turn
Light: Light recoil affects accuracy, reducing hit chance of subsequent bullets. Does not impair movement speed or agility.

Defier
Features insane caliber and many pellets in a round to ensure a hit even if the shooter is a complete pan-faced corpse-eating death-loving wanker.
Double-barreled, one round per barrel, break-action reload.
Has an inbuilt stock-mounted shell generator which reconstructs new shells at about 1 shell/10 seconds for use with Defier. Heavy recoil is mitigated by equally heavy weight.
Damage in Construct: 2x40/turn at point blank, expected 1x20 at 20-30m range, 1x5 beyond that. Can fire both shots per turn, but suffer Knockdown for one turn, doubling amount of pellets fired
Heavy: 40% less pellets hit if user has <100 HP and cannot properly wield such a massive weapon.
