There’s quiet on a dB meter, and then there’s quiet to the ear. With JK Armament’s Tone Technology, you get both! Tone Technology refines the 155 RPX 46 sound signature for a solid, deep tone that’s more pleasing to the ear.
Lightweight, durable, and fully Mission Configurable, the JK 155 RPX 46 suppressor is right at home on every 45 Caliber firearm in your collection. With it exceptional design and modularity, it excels on anything from Handguns, to Lever-actions, to Straight Wall Hunting Rifles, and even Full-Auto Subguns. This allows you to move the RPX 46 between your different 45 caliber firearms (45ACP, 450, 45-70, 458 SOCOM, 458 Win Mag), while still being compatible with your smaller centerfire cartridges (223 / 5.56, 308, 6.5, 350, 300 blackout, 357, Etc…).
A Grade 5 Titanium JK 155 PRO blast baffle and seven user-configurable 7075 billet JK 155 LT modular baffles combine for an ideal balance of strength and weight. JK’s Tone Technology delivers industry-leading sound reduction along with a solid, deep tone that’s more pleasing to the ear.
In its micro configuration, the RPX 46 is 3.3 inches long and weighs a shockingly light 3.7 ounces. In its full configuration with all eight baffles, it’s still only 8.7 inches long and weighs just 11 ounces. By simply adding or removing baffles – no specialized tools needed! – the user is able to choose the length, weight, and sound suppression that’s right for the firearm and the mission.
In addition to the modular baffle and end cap design, the 155 RPX is even more Mission Configurable thanks to its industry-standard HUB 1.375×24 mount size. This means dozens of mounting options are instantly available! From the included JK 155 LT Quick Attach Taper Mount, which fits our industry-leading JK muzzle devices (Including the Bald Eagle Compensator Muzzle Device in the packaging), to pistol boosters / nielsen devices, direct thread fixed mounts, tri-lug mounts, QD / QA mounts, and much more, the versatility of the HUB standard can’t be overstated.
The JK 155 RPX 46 is rated for .45cal full-auto use as well as for use on other pistol calibers from 25 ACP on up to 357 Magnum, and even on 300 Blackout, all without barrel length restrictions. It can even be used on rifles chambered in 223/5.56, 350 Legend, 308 Win, 300 Win Mag, and more with varying barrel length requirements. This makes the 155 RPX an extremely versatile choice! See the Barrel and Caliber Rating chart below for barrel length restrictions and more information.
(All RPX 45s produced after Serial Number RPX0848 are now marked as RPX 46. This is primarily an In-line change to highlight the multi caliber capabilities of the RPX 46.
