At Halcyon Defense, we specialize in producing a variety of suppressor mounts and thread adapters for both common and obscure firearms. All of our products are made to the highest standards on CNC machining equipment to ensure your muzzle device or sound suppressor is safely and securely mounted to your weapon.

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.
