Rugged Alaskan 360 Direct-Thread Suppressor, 5/8x24 The Rugged Alaskan 360 in this configuration combines the Alaskan 360 suppressor with a 5/8x24 direct-thread interface. The direct-thread designation identifies the mounting format, making thread compatibility an essential part of selecting this version for a host firearm. The listed caliber range extends from 9mm through .338 Lapua. Caliber coverage and mounting compatibility describe separate aspects of the suppressor. A suitable host must fall within the applicable caliber rating and use the correct mounting arrangement. This 5/8x24 version is therefore a specific configuration to evaluate by both thread pattern and caliber, rather than by the Alaskan name alone. It provides a clearly identified option for buyers looking for the Alaskan 360 in a direct-thread format. Key Features Alaskan 360 model: Rugged Suppressors' multi-caliber product identity.
