AK-47 Family
This adapter will allow you to attach standard 7.62mm accessories and sound suppressors to any AK-pattern rifle with the standard M14 X 1.0 LH threads. This also includes most RPK and PSL pattern guns.


While our adapters are made to exacting standards and are concentric - the same cannot be said about all AK's. It is very important to double check baffle clearance before you fire the weapon with a suppressor attached. So far we have only seen one RPK that we would not feel comfortable shooting suppressed without having a qualified gunsmith repair.

By purchasing Halcyon Defense thread adapters, I acknowledge that: Halcyon Defense produces precision thread adapters that are held to the most stringent quality control standards possible. The end user of Halcyon Defense products is responsible for ensuring that barrels, suppressors, and all other devices that Halcyon Defense thread adapters may be utilized with have threads that are concentric to the bore, and that any projectile that passes through these devices will do so without striking any component in the weapon system. Some manufactures do not adhere to the same standards and precise tolerances as Halcyon Defense, and Halcyon De mage to any component that occurs while using Halcyon Defense thread adapters.
