SilencerCo AC626 Piston 17-4 Stainless Steel Multi-Caliber 13.5x1 LHM XL

The SilencerCo AC626 is a replacement multi-caliber suppressor piston in size XL. It is machined from 17-4 stainless steel and heat treated for maximum durability, and features 13.5x1 LHM left-hand metric threads that mate to host pistol barrels cut to that pattern.

SilencerCo's pistons are interchangeable across their suppressor lineup, so a single host pistol can be paired with different compatible suppressors by simply changing the piston to match the barrel's bore depth. The AC626 is rated for multi-caliber use and carries SilencerCo part number AC626.

The AC626 is compatible with the following SilencerCo suppressor families:

• Octane Series
• Osprey Series
• Omega K Series
• Hybrid 46

Whether replacing a worn piston or reconfiguring your suppressor for a new host pistol, the SilencerCo AC626 delivers the OEM-grade fit and finish needed to keep your suppressor running reliably.
