AAC Ti-Rant 45 Piston - .578X28

Product Details

Swap hosts the right way with the AAC Ti-RANT 45 piston in .578x28. This ASAP/Nielsen piston threads to the common .45 ACP standard, giving your Ti-RANT 45 the correct movement for reliable cycling on semi-auto pistols.

It is machined from heat-treated stainless steel with a matte bead-blast finish and each unit is engraved with thread pitch and rotation, so setup is simple and repeatable. If your pistol is a 1911 or FNP with short exposed threads, verify whether you need the “short” .578x28 variant; otherwise, this standard .578x28 piston is the move.
