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

The KRISS Vector Limited Edition Alpine features the KRISS Vector MK5 Modular Rail l is 5″ long and features a full length bottom rail and 5 slot rail segments at the 3 and 9 o’clock positions.

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 and bolt catch button are not just for looks. When the charging handle is pulled, the dust cover opens, and the bolt lock holds the bolt plate back, revealing the hop up, for unencumbered adjustment.

The DS150 stock is the same model featured on some of the Vector AEG's realworld counterparts. Constructed of the same fiber reinforced polymer as the receivers, the stock is adjustable to 6 positions with QD, and sling strap, accommodations on both sides.

Extended capacity means extended battery life. The KRISS Vector Extended Battery Cap is a standard feature of the KRISS Vector SMG Limited, and allows ample room 1200mAh lithium polymer stick batteries.

A representation of decades of experience in airsoft and tech work went into creating the highest performing and most rugged gearbox from the factory. Features that would require custom fabrication and cutting in years past are standard in the Nautilus.

The KRYTAC Trident Series AEGs were the first M4 style airsoft replicas to utilize a numbered rotary hop up, with tactile feedback for precision hop up adjustments.

The Nautilus MOSFET safeguards the circuitry and is strategically positioned at the rear of the gearbox in order to maximize space in the battery compartment.

The Nautilus Gearbox achieves perfect AOE out of the box thanks to the enlaged padding on the rear of the cylinder head and the absent second tooth on the piston.

Modern T-plugs offer superior performance and save significantly on space compared to the traditional airsoft batttery plug.
