The booster decouples the barrel from the suppressor during the cycling process, allowing the barrel to recoil freely and actuate the action—critical for semi-automatic pistol-caliber firearms that depend on barrel movement for reliable function.\u003c\/p\u003e\u003cp\u003eThis assembly features the industry-standard HUB (Hub Universal Booster) thread pattern, making it compatible with a wide range of HUB-compatible suppressors. Machined from durable materials with a corrosion-resistant finish, the unit threads directly onto 1\/2x28 TPI muzzles commonly found on 9mm and .22 LR barrels. Installation is straightforward: thread the booster onto the muzzle, then attach your HUB-compatible suppressor. Note that this is a booster assembly only—suppressor sold separately. Verify compatibility with your specific firearm and suppressor before installation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Booster Assembly (Nielsen Device)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2x28 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuppressor Mount:\u003c\/strong\u003e HUB Universal Pattern\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 Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e Pistol-caliber carbines and firearms requiring a booster for suppressed operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Angstadt Arms","offers":[{"title":"Default Title","offer_id":48301622264063,"sku":"ANGAAHUBBA228","price":140.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5809226.jpg?v=1773890901","url":"https:\/\/doublestackstore.com\/products\/angstadt-hub-1-2x28-booster-assembly","provider":"Double Stack Store","version":"1.0","type":"link"}
