Direct Thread
Also: Direct-Thread Mount
A suppressor that threads straight onto the muzzle, simple and concentric but slower to swap than a quick-detach mount.
A direct-thread mount is the simplest way to attach a silencer: the can screws directly onto the rifle’s muzzle threading with no intermediate adapter. Because nothing sits between the threads and the can body, this method tends to give excellent concentricity, which keeps the bore line of the suppressor aligned with the bore of the barrel and reduces the chance of a baffle strike. Many precision shooters prefer it for exactly that repeatable, rigid fit.
The trade-off is convenience, since a direct-thread can must be unscrewed by hand and can loosen under vibration or seize on after heat cycling. A quick-detach system instead locks onto a dedicated muzzle device, trading a little concentricity for fast on-and-off swaps between rifles. The right choice depends on whether the shooter values a permanent, tuned setup or quick interchangeability.
