The Tokyo Marui Saiga-12K is a faithful replica of the real steel Saiga 12K, K stands for "Korotkaya" which is "Short" in Russian. This gas airsoft shotgun is semi-automatic, and fires 3 BBs at the same time. This feature is similar to most Tokyo Marui shotgun offerings, but do note that, unlike the Tokyo Marui M870 series pump action shotgun, the Tokyo Marui Saiga-12K could not be set to fire 6 BBs in the same time or has a selector for fully automatic fire, like the Tokyo Marui AA12 or the SRG-12 electric airsoft shotgun.  In return, it delivers tight and accurate groupings, being able to send all 3 BBs in a 1-inch group at 10 meters while giving the user a sharp recoil impulse even when using weaker HFC134a gas.
Externally, this gas airsoft shotgun features an adjustable front sight, AK74M style folding stock, an AK style dovetail rail that allows you to add optics to the Saiga 12K gas airsoft shotgun as well as a 23mm threaded barrel. 
Finally, the gas magazine that comes with the Tokyo Marui Saiga-12K is modelled after the real Saiga 12. This gas magazine, however, holds 45 rounds, allowing you to pull the trigger 15 times before needing to reload. The Tokyo Marui Saiga-12K magazine comes with a celsius temperate thermometer inside, which can be accessed by pushing the tab under the knocker valve and pulling the shell apart.
