{"product_id":"b-t-rotex-sf-muzzle-brake-556","title":"B\u0026T ROTEX-SF Muzzle Brake 5.56 NATO – Quick-Detach Suppressor Host","description":"\u003cp\u003eThe B\u0026amp;T ROTEX-SF Muzzle Brake is a precision-machined QD mount designed to serve dual purposes: effective recoil reduction during unsuppressed fire and a secure attachment point for B\u0026amp;T ROTEX-series suppressors. Featuring aggressive side ports, this brake redirects propellant gases to mitigate muzzle rise and felt recoil in 5.56 NATO chamberings, while its indexed locking collar system enables rapid suppressor attachment without tools or timing adjustments.\u003c\/p\u003e\u003cp\u003eManufactured from heat-treated steel with a durable black oxide finish, the ROTEX-SF brake installs via standard 1\/2x28 threads common to AR-15 pattern rifles and other 5.56 platforms. The integrated locking mechanism uses spring-loaded ball detents to ensure repeatable zero when mounting compatible suppressors. Note: This is a firearm component only—attaching a suppressor requires compliance with NFA regulations including ATF Form 4 approval and applicable state\/local laws.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Quick-Detach Muzzle Brake \/ Suppressor Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 5.56 NATO \/ .223 Remington\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2x28 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-Treated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, 5.56 NATO rifles with 1\/2x28 threaded barrels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Suppressors:\u003c\/strong\u003e B\u0026amp;T ROTEX-SF series (requires NFA compliance)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026T USA","offers":[{"title":"Default Title","offer_id":47942985941247,"sku":"BANDTSD-145163","price":160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5620062.jpg?v=1766570962","url":"https:\/\/doublestackstore.com\/products\/b-t-rotex-sf-muzzle-brake-556","provider":"Double Stack Store","version":"1.0","type":"link"}
