AAC TI-RANT 45 Piston .578x28 – Replacement Piston for AAC TI-RANT 45 Suppressor

The AAC TI-RANT 45 Piston with .578x28 thread pitch is a replacement or alternate Nielsen device (booster) piston designed for use with the AAC TI-RANT 45 suppressor system. This piston enables reliable cycling on tilting-barrel pistols by allowing the barrel to recoil independently of the suppressor, which is essential for semiautomatic function when shooting suppressed. Swapping pistons lets you mount your TI-RANT 45 on different host pistols with varying thread pitches without removing the suppressor from service.

Machined to AAC's specifications, this piston threads directly onto barrels with .578x28 TPI threads and seats into the TI-RANT 45's booster housing. Installation is straightforward: thread the piston onto your pistol barrel, then attach the suppressor to the piston. Confirm proper alignment and hand-tightness before firing. This piston is compatible only with AAC TI-RANT 45 suppressors and requires that your host firearm is already NFA compliant with an appropriate tax stamp for the suppressor.
