KRYTAC, established in Southern California in 2013, is a dedicated product research and design team of the Switzerland-based firearms manufacturer KRISS Group. The primary focus of KRYTAC is to engineer premium airsoft products for recreational use. Additionally, KRYTAC also specializes in the advancement of cutting-edge professional training systems. The KRYTAC team is comprised of highly experienced firearm and airsoft professionals who have come together for one common goal, to provide premium products that evolve individuals beyond their boundaries. Their mission can be seen in the KRYTAC brand name, which is derived from the legendary sea creature The Kraken. The Kraken was feared, and revered, for its power and dominance in the sea. No other creature could match The Kraken in strength and speed. The spirit of The Kraken lives on in KRYTAC. With the Alpha CRB M4 Full Metal AEG, you can unleash that power in your own battlefield without spending a fortune.

The Alpha CRB is a versatile carbine-length M4 airsoft rifle that can be used effectively in close quarters battle and wide open outdoor engagements. The Alpha CRB utilizes a 10.5-inch barrel and a 10-inch free floating Alpha rail system. The aluminum receivers feature a stamped KRYTAC logo and a dull matte black finish. It comes with sling loops for carrying your KRYTAC CRB around and adjustable iron sights for honing in on opponents. Additional features include an ambidextrous fire selector and a locking bolt that provides easy access to the KRYTAC rotary hop-up system.

This system is a fine example of how you can customize your Alpha CRB M4 Black Airsoft Rifle. The KRYTAC rotary hop-up has 15 adjustment settings and a numbered adjustment wheel for a quick reference point to determine how much hop is needed. As such you can fine-tune accuracy for close-, mid- or long-range targets. The KRYTAC adjustable battery stock features two different battery configurations as well. Nunchuck-style batteries can fit in the tubes or a small lithium polymer brick battery can fit at the rear of the stock in front of the buttpad. A third battery option for the Alpha CRB is a stick battery in the buffer tube. The stock also features two QD sling swivel divots as well as a loop for strap type sling attachments.

The Alpha CRB has the latest in shooting sports technology and the internals to back them up. It features a reinforced 8mm ball bearing gearbox with integrated MOSFET to regulate electronic signals and to protect the trigger contacts. The corners of the gearbox that surround the cylinder feature a smooth radius, as opposed to a 90-degree angle, to prevent fracture. Also, the gearbox shell has a small window on the left side where lubrication can be applied directly to the gears or piston. This window is also convenient for inspecting the angle of engagement with the gearbox fully assembled. A special coating resists corrosion from water or debris. Additional gearbox features include a modular spring guide system that will allow the spring to be changed without completely disassembling the gearbox.

The KRYTAC piston is made of a durable, lightweight polymer and features four metal teeth with the 2nd to last tooth absent to reduce jamming. The cylinder head is padded with an enlarged rubber bumper to optimize the angle of engagement and to absorb energy from the impact of the piston assembly. The material for the gears have been specially formulated to be very strong - Rockwell test figures on the KRYTAC gears are much higher than industry norms. Turning all of the drive train components is the KRYTAC high-torque motor capable of 20,000 revolutions per minute unloaded.

The Alpha CRB Carbine is the best multipurpose AEG of the Alpha series that can perform at a high level in a multitude of different scenarios. It has the power and the accuracy to perform from almost any distance and is one of the most reliable airsoft rifles you'll find.
