If you are looking for a suppressor for your lil' AK, you have found the right one. The real world PBS-4 is designed for use on the AKS-74U rifle, but has also been seen in use on full length AK74s!

Full description


Introducing the 5KU PBS-4 suppressor, a funky-looking muzzle device that will give your AK a mean ruskie look. The PBS-4 interior is massive, and filled with foam, meaning you will get a much better suppression effect from this monster than most other Airsoft suppressors. The design is particularly weird due to its intended role, to suppress the AKS-74U, which requires a large moderator/gas booster in order to ensure enough gas is sent back into the system to cycle the bolt. Though the look may be marmite, once it is installed on an AKS74U you will be convinced. The suppressor's built in threads are for AK 24mm CW muzzle threads, though the suppressor comes with an adaptor for standard 14mm CCW threads, should you want to use this on another weapon platform, or if your AK has 14mm CCW male threads. This suppressor has a specific mounting orientation to keep faith with the real PBS-4, though if it mounts wonky once threaded on the suppressor body can be rotated using the collar and steel locking piece near the barrel end. By lifting up the locking piece, you can rotate the suppressor body which will lock in place when you lower the locking piece. The front section of the suppressor can be unthreaded in order to access the internals, should you have your own secret suppression formula you would like to add or to remove the included foam inserts to install an extended inner barrel.
