Rogue Core Deepcore GK2.

This innovative submachine gun swaps out the conventional spring recoil mechanism for a fully magnetized receiver assembly. Originally designed for security operations aboard space stations, the weapon fires caseless tumbling ammunition that inflicts maximum tissue damage without penetrating fuselage walls or reinforced windows. A downside to this design is that hits to armor are comparably ineffective.

But what really makes the Decker popular is its sleek and ergonomic design.
