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.

"This gun is one of the best I've owned. Cqb, this gun rocks. Mid range, right on target. I've even taken out a few long range. Everyone who tries it is amazed how well it hits and range. Only made a few adjustments to it, like a hevier spring to up the fps, and a motor to handle it.

"Got this from the Fourth of July Box of Awesomeness and it shoots wonderfully with a 9.6v 1200mAh battery (I don't own a LiPo, so I haven't tested with that yet.) Stock mag feeds well with 6mmProShop .25g BBs, I plan to bring this to a nearby field tomorrow to get some play time in. Also, rotary hop up and locking bolt are major benefits of the Krytac series, big A+ there.

Side note, I personally think this looks much better with a reflex red dot than with a T1 red dot, but that is super subjective.

"I have one of these and I love it to death. I got mine from a sale in Colorado Springs, Co, and it has some adjustments that are not stock on this. Mine has deans lipo batteries, so it uses a different charger. The connections on a deans are a little bit better for some hardcore play and use. I re-tightened and adjusted the internals and that's all the modification I did on my rifle.

It's a beast in cqb, and mid range engagements.
Very simple and basic, bare bones and works well with just one sight.
Can handle major abuse
Incredible accuracy for a cqb.
Lots of room in the trigger well, for gloves

Only top side picatinny for an optic. No other picatinny rails for handguards, or other accessories.
This is a small gun, don't use it if you want a full size ar-15 type rifle.
