Advanced Armament Company
The AAC Ti-Rant 45 Piston in .578x28 is a quick-swap component that unlocks real versatility from your Advanced Armament Company suppressor. Instead of being locked to a single host rifle, this piston lets you move your Ti-Rant 45 between different firearms by simply swapping out the rear piston assembly. If you run multiple rifles with different barrel threads, this is the practical solution that keeps your suppressor in the fight rather than sitting idle waiting for a threaded barrel match.
Built from heat-treated stainless steel, the piston handles the thermal cycling and pressures of centerfire rifle shooting without degradation. The bead-blasted matte finish resists corrosion and hides carbon fouling—important when your suppressor spends time in the field and at the range. Each piston arrives engraved with the thread diameter, pitch, and rotation direction, so installation is straightforward and there's no guessing about which way it goes in.
This accessory is essential if you're consolidating your suppressor collection or want the flexibility to thread your Ti-Rant 45 onto multiple uppers or barrels as your shooting needs evolve. Swapping pistons takes minutes and requires no tools—just access to the rear of your suppressor.

No. The piston swap is designed to be straightforward and requires no special tools or gunsmithing. Simply access the rear of your suppressor and replace the old piston with the new one.
Yes. The whole point of the piston system is that you can own multiple pistons in different thread sizes and swap them as needed to move your suppressor between rifles with different barrel threads. This is the key to maximum suppressor versatility.
