{"product_id":"yhm-nielsen-piston-1-2-28-9mm-slv","title":"Yankee Hill Machine Nielsen Piston 1\/2-28 Thread – 9mm Suppressors","description":"\u003cp\u003eThe Yankee Hill Machine Nielsen Piston enables reliable cycling of tilting-barrel 9mm pistols when a suppressor is attached. This spring-loaded booster decouples the suppressor from the barrel during the unlocking cycle, allowing the slide to move freely and the firearm to function as designed. Without a Nielsen device, many browning-type pistol actions will short-stroke or fail to cycle under the added weight and inertia of a suppressor.\u003c\/p\u003e\u003cp\u003eThis piston features 1\/2-28 threads for direct attachment to most 9mm pistol barrels. Constructed from durable steel with a silver finish, it installs between your threaded barrel and compatible suppressor. Check your suppressor manufacturer's specifications to confirm piston compatibility before purchase.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Nielsen Device \/ Booster Piston\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2-28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 9mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e Tilting-barrel 9mm pistols with 1\/2-28 threaded barrels\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yankee Hill Machine Co","offers":[{"title":"Default Title","offer_id":47943799144703,"sku":"YHM-2060-28","price":69.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2888887.jpg?v=1766601459","url":"https:\/\/doublestackstore.com\/products\/yhm-nielsen-piston-1-2-28-9mm-slv","provider":"Double Stack Store","version":"1.0","type":"link"}
