The Alpha SDP is a compact, lightweight, full metal AEG that combines the maneuverability of a pistol with the firepower and capacity of a rifle. Based on the AR design, the Alpha SDP features a futuristic aluminum hand guard with a smooth finish for a comfortable grip. The aluminum receivers feature a stamped KRYTAC logo and accept airsoft M4 style magazines. Additional features include an ambidextrous fire selector and a locking bolt that provides easy access to the KRYTAC rotary hop-up system. 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. The battery is stored in the buffer tube of the KRYTAC Compact Carbine stock, which was designed to provide ample room for a wide range of batteries. The external features of the Alpha SDP are engineered for durability and ergonomics, the heart of the performance lies within the gearbox.

Internally, the Alpha SDP 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 angle, to prevent fracture. Also, the gearbox shell features 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.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 4 metal teeth, with the 2nd to last tooth absent. The Cylinder head is padded with an enlarged rubber bumper to optimize the angle of engagement and to absorb energy form the impact of the piston assembly. The material for the gears have been especially 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 30,000 revolutions per minute unloaded.

The Alpha SDP provides the familiarity, controls, and firepower from a rifle and also offers the compact package. It is the ideal AEG for high speed engagements in tight and confined spaces.
