If you feel uncomfortable with the Sound Hog attached to your TM New Generation AK-102 with Blowback and Recoil Engine, PDI-Japan gives you the answer to your concerns. They have released a Steel Carbine Muzzle for the AEG and is made with cut carbon steel with black oxide finish. It is a 24mm screw thread that is designed at an angle to match only the TM AK-102 thread. You'll need to attach the muzzle slowly as it has been coated with a sealant for the front sight screw as forcibly putting it will remove the sealant.
