The SilencerCo Piston (Model AC1756) is engineered for easy installation and versatile use across various pistols and calibers. Crafted from heat-treated 17-4 stainless steel, this piston ensures maximum durability and resistance to wear during regular operation. Designed as part of the Nielsen device, it facilitates semi-automatic cycling by allowing the unlocking of pistol barrels, making it suitable for a range of firearm configurations. The piston features female threading that securely attaches to SilencerCo threaded barrels, providing a reliable connection. Its 1/2X28 thread size enables indexing directly on the muzzle of the barrel, which is particularly advantageous for small-profile pistol barrels with insufficient shoulder diameter for traditional mounting. An optional Fixed Barrel Spacer can be added for fixed barrel applications, increasing versatility and compatibility. This piston is an essential component for firearm owners seeking durable, easy-to-install parts that enhance firearm function and maintenance.
