The AAC Ti-Rant 45 Adapter for 300 AAC BLK Subsonic Only gives Ti-Rant 45 and Ti-Rant 9M HD suppressor owners a simple way to mount their can directly to a 5/8x24 threaded barrel. This dedicated fixed-barrel adapter replaces the standard piston and driving spring, creating a solid, secure interface that is purpose-built for subsonic 300 AAC Blackout use.

Designed specifically for fixed-barrel hosts, this adapter uses an innovative wave spring to keep tension on the rear cap, helping prevent the silencer from loosening during extended strings of fire. When installed correctly there is no gap between the suppressor body and the rear cap, and no separate fixed-barrel spacer is required. Ideal for quiet range sessions or training with subsonic 300 BLK, it reflects Advanced Armament’s focus on practical, shooter-friendly suppressor accessories.
