This SilencerCo Piston Kit is everything you need to reliably run a suppressor without the guess work. The Piston Kit features five pistons to meet the most common needs of firearm owners looking to use a suppressor, a .578x28 piston, 1/2x28 piston, M16x1 LH piston, M13.5x1 LH piston and 9/16x24 piston. SilencerCo pistons have female threading that attaches to threaded barrels and are interchangeable with 9mm and .45 caliber. Pistons are built with 17–4 stainless steel and heat-treated for optimal durability and a long service life. In addition, these pistons boast a black nitride finish for increased wear-resistance and lubricity making them extremely reliable. Without a piston and Nielsen device on your setup, the added weight of the suppressor can prevent the barrel from unlocking and fully cycling. With a piston and Nielson device attached it increases pressure allowing the barrel to unlock and cycle the action resulting in a smooth and reliable piston and silencer setup on your pistol. If you are using a fixed barrel application, you will need to use a fixed barrel spacer to ensure proper functioning.
