SilencerCo Piston 37/64-28 XL, Black

Our pistons are engineered for versatility, allowing quick and easy changes to accommodate different host firearms and calibers. Each piston is precision-machined from 17-4 stainless steel and heat-treated to ensure maximum durability and longevity. As a critical component of the Nielsen device, the piston facilitates proper movement and enables reliable semi-automatic cycling for unlocking pistol barrels. For use with fixed barrel firearms, simply add a Fixed Barrel Spacer to optimize performance. Designed with female threading, SilencerCo pistons seamlessly attach to SilencerCo threaded barrels, providing a secure and reliable fit for enhanced suppressor functionality. XL pistons are ideal for firearms that require additional length between the threaded barrel and the silencer, improving fit and performance
