HK SPIW HECKLER & KOCH SPIW (Special Purpose Individual Weapon) / GERMANY Very little is known about this weapon, which was the first ever entry of the German firm HECKLER&KOCH in the OICW program. As you can see, this weapon is an "evolution" of the "standard" G-36 assault rifle. It features a total plastic frame to reduce weight, a S-E-3-F trigger group and a selector for standard 5'56-NATO ammunitions or GRENADE firing. It has a MONSTROUS double-barrel side-by-side design, with a BIG grenade magazine placed BEYOND the "standard" 30-rounds 5'56-NATO ammo clip (uses the same ones of the G-36 series, as you can see).
