This Nielsen device (booster assembly piston) ensures reliable cycling in tilting-barrel pistols by allowing the barrel to recoil independently while the suppressor remains stationary during operation. The 13.5x1 left-hand thread pitch is a European standard found on select pistol models.\u003c\/p\u003e\u003cp\u003eMachined from heat-treated steel, this piston threads directly onto compatible barrels and mates with the Illusion 9 booster housing. Replacement pistons are essential for adapting suppressors to firearms with different thread pitches or replacing worn components. AAC pistons are serialized components—confirm compatibility with your suppressor model before ordering.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Nielsen Device Piston\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Suppressor:\u003c\/strong\u003e AAC Illusion 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 13.5x1 LH (Left-Hand)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-Treated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Replacement piston for European-threaded pistol barrels\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AAC (Advanced Armament)","offers":[{"title":"Default Title","offer_id":47944253210879,"sku":"AD64245","price":74.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/ad642463e30.jpg?v=1766634278","url":"https:\/\/doublestackstore.com\/products\/piston-illusion-9-13-5x1lh","provider":"Double Stack Store","version":"1.0","type":"link"}
