KRYTAC receivers are made from an aircraft grade aluminum alloy and molded to a modern, billet-style, aesthetic. The alloy construction offers lightweight strength and realistic durability, with enhanced features, such as enlarged trigger guard for gloved hands, and a flared magwell for seamless reloading.

The KRYTAC TR213 is a 13" modular handguard, that is CNC machined from T6 aluminum, then hard coat anodized for a sturdy feel and finish. The robust material and precise machining provide a solid foundation for, and ensure proper fitment of, M-LOK picatinny rails and accessories.

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 KRYTAC Adjustable Battery Stock is tailor made for optimum airsoft utility and comfort. Adjustable to 6 positions, with multiple sling mounting options, this stock can be adapted perfectly to your environment and load out preferences. The large cavities in the stock provide accommodation for a wide variety of 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.
