JK Armament 155 RPX 30K .30 caliber Suppressor, Black The JK Armament 155 RPX 30K combines a titanium blast baffle with a lightweight aluminum baffle stack in a modular .30 caliber suppressor. The compact K format emphasizes a manageable overall profile while retaining a configurable baffle system. The Black suppressor includes a taper mount and 5/8x24 Bald Eagle muzzle device, making compatible rifles and fixed-barrel hosts the starting application for the supplied mounting system. The 1.55-inch diameter keeps the body profile consistent across its approved modular configurations. Choose the 155 RPX 30K .30 caliber Suppressor, Black at BattleHawk Armory. Titanium Where the Blast Arrives First A Grade 5 titanium blast baffle occupies the first baffle position, followed by 5 7075 aluminum baffles. The hybrid construction places the stronger, heat-resistant titanium component at the blast end while using aluminum to limit overall weight. It is a considered material mix for an owner who values a manageable suppressor without treating every application as an all-steel duty cycle. Configurable Length and Sound Reduction The 6-baffle system supports approved shorter and longer configurations. Shortening the assembly reduces length and weight at the muzzle; retaining more baffles increases the available suppression volume. The modular components also provide service access. The best arrangement depends on the firearm, cartridge, and intended use, rather than the model name alone. Included Mounting Components The RPX 30K includes a taper mount and 5/8x24 Bald Eagle muzzle device. The Bald Eagle attaches to a compatible 5/8x24 barrel and provides the interface engaged by the suppressor's taper mount. The muzzle device and taper mount perform separate jobs; together they equip an appropriate fixed-barrel host for the suppressor. End Cap and Mounting Flexibility A flat flash-cut end cap completes the suppressor. The 1.375x24 HUB rear interface supports compatible mounting options, subject to the required internal clearance and approved host application. A tilting-barrel pistol requires its own approved mounting arrangement; the included taper system should not be treated as a piston booster. Cartridge-Specific Use Limits The RPX 30K supports .300 Blackout and approved .30-caliber rifle applications. Its .308 Winchester sporting-use rating distinguishes subsonic use from supersonic use, with a 12.5-inch minimum barrel for supersonic ammunition. .300 Winchester Magnum sporting use requires at least an 18-inch barrel. The caliber, ammunition, barrel length, and approved firing schedule must be considered together.
