The KRISS Vector SMG AEG receivers are made from a similar material to its real-world counterpart. Fiber reinforced polymers offer the best balance of robust durability and lightweight maneuverability.

The left and right side of the Vector SMG hand guard feature mounting points for picatinny rail sections, for the addition of aiming devices, such as lights or lasers. At the 6 o'clock position is a fixed, 7-slot, picatinny rail that is perfect for stabilizers, such as vertical grips or hand stops.

When folded, the back up sights sit a mere 14.2mm above the receiver top rail, allowing them to be tucked neatly behind, and underneath, optics and other aiming devices.

Ambidextrous switches allow the operator to maintain control of the AEG, regardless of dominant hand manipulation.

The charging handle is not just for looks. When the charging handle is pulled, the dust cover opens, revealing the hop up, for unencumbered adjustment.

The KRISS Vector SMG folding stock is constructed of the same fiber reinforced polymer as the receivers. With the push of a button, the stock folds to the side, reducing the overall length of the platform by 9". Additionally, the butt pad can be extended to match the operator's preferred length of pull, and the metal sling loop provides a sturdy foundation for a sling strap.
