MK23 Special Operations GNB with Suppressor by ASG

The MK23 SOCOM is a semi-automatic gas pistol that has earned the nickname "silent killer" among airsoft players. Thanks to its fixed slide, its main advantage is quiet operation, making it a top choice for snipers firing from concealment. This version includes a mock suppressor that conceals an extended inner barrel, improving both range and precision. The pistol also features a standard RIS rail for mounting accessories like flashlights, as well as an adjustable hop-up for dialing in BB trajectory. Powered by Green Gas, the MK23 remains well-balanced and easy to handle despite its length of over 42 cm with the suppressor attached.
