Krytac's TRIDENT series airsoft rifles took the airsoft market by storm with overwhelmingly good features, performance, and demand. While they also carried a premium pricetag, Krytac was determined to offer the same kind of high quality AEGs at a more affordable price point and thus their ALPHA series of AEGs were born. 

The SDP is Krytac's ultra-compact AEG variant with a combination mock suppressor and hard guard combo. The ported octagonal SDP end houses the entire barrel assembly and gives the SDP it's unmistakably unique look. The same rock solid aluminum receivers sporting the Krytac logo still feature their lefty-friendly ambidexterous fire selector, enlarged trigger guard, and locking charging handle, bolt, and dust cover which provides easy access to the hop up assembly. Changing the hopup is a breeze with Krytac's numbered and locking rotary wheel style hop up that securely holds your settings in place. Removable front and rear adjustable iron sights can be used alone or with aftermarket optics such as red dots or scopes. A metal sling plate between the buffer tube and receivers. The unique compact carbine stock's all metal design can hold various PEQ style LiPO batteries. It's super compact design has two positions, collapsed and extended. When collapsed, this AEG is no longer than 18.5"

Internally, the ALPHA SDP uses the same tried and true Nautilus Version 2 gearbox. Sporting features such as  8mm ball bearings, easy-change spring system, AOE corrected piston, piston teeth, and cylinder heads, and more. The gearbox shell itself is uniquely designed to reduce chances of fracturing as well as has a viewport for viewing AOE and lubricating gears. Krytac included an in-line MOSFET to reduce wear and tear on the trigger contacts as well as improve responsiveness. A 20K revolution Krytac motor allows for 20+ BBs per second rate of fire when using 11.1v Lipo batteries (not included).
