AAC TI-RANT 45 Short Piston .578x28 for 1911

The AAC TI-RANT 45 Short Piston provides the interface between your 1911 pistol barrel and TI-RANT suppressor. This piston translates the Nielsen device (booster) action that allows reliable semi-automatic cycling when shooting suppressed. Without a properly matched piston, tilting-barrel pistols often fail to cycle when a suppressor adds reciprocating mass to the barrel assembly.

Machined for .578x28 thread pitch, this short-length piston is designed specifically for 1911 platform pistols chambered in .45 ACP. The piston threads onto your threaded barrel and accepts the TI-RANT suppressor's booster assembly. Durable construction ensures consistent performance across thousands of suppressed rounds.
