Piston Kit by SilencerCo

Product Description

The SilencerCo AC728 Piston Kit is a factory replacement suppressor mounting component designed to allow compatible handgun suppressors to function reliably on pistols with unlocking, tilting-barrel actions. As part of the Nielsen device assembly, the piston enables proper cycling while maintaining a secure connection between the suppressor and threaded barrel.

Manufactured from heat-treated 17-4 stainless steel for maximum durability, the AC728 is engineered to withstand repeated firing cycles and harsh shooting conditions. Its interchangeable design allows shooters to configure compatible SilencerCo suppressors for different firearms by selecting the appropriate thread pattern for their host pistol.

Product Highlights

The AC728 Piston Kit plays a critical role in suppressor performance on semi-automatic handguns. By allowing the suppressor to move independently during the firing cycle, it helps maintain reliable function while reducing stress on the firearm and suppressor mounting system. SilencerCo's use of heat-treated 17-4 stainless steel ensures exceptional strength and longevity even under heavy use.

Its interchangeable design makes it a versatile solution for suppressor owners who run multiple threaded pistols. By simply changing pistons to match barrel thread patterns, shooters can utilize the same suppressor across various compatible hosts.
