SilencerCo AC634 Harvester 300 Direct Thread Mount 5/8x24 Black

The SilencerCo AC634 is a direct thread mount adapter designed to attach the Harvester 300 suppressor directly to a threaded rifle barrel. This interchangeable, modular thread adapter features a 5/8x24 thread pitch and is built for the muzzle threading commonly found on 300 Win Mag and similar magnum-caliber rifle platforms.

Constructed from stainless steel with a black finish, the AC634 delivers a durable, corrosion-resistant interface between the suppressor and host barrel. The direct-thread configuration provides a secure, streamlined attachment without requiring a separate muzzle device or quick-detach mount - ideal for users wanting a clean, low-profile setup on a fixed-barrel rifle.

Purpose-built for the Harvester 300, this direct thread mount allows the suppressor to be installed on virtually any barrel with matching 5/8x24 threading. Installation is straightforward: thread the AC634 onto the barrel, then thread the Harvester 300 onto the mount. It is a practical accessory for shooters running magnum-caliber rifles already equipped with a Harvester 300 suppressor.
