Its compact single-chamber design redirects combustion gases to counteract recoil forces while maintaining a shorter overall length compared to multi-baffle brakes, making it well-suited for both precision rifle competitions and hunting applications where maneuverability matters.\u003c\/p\u003e\u003cp\u003eThis brake features 5\/8x24 TPI threading, the standard for most 6.5 Creedmoor barrels on AR-10 pattern rifles and many bolt-action platforms. Machined from heat-treated steel with a durable black nitride finish, it installs with standard armorer tools and includes a crush washer for proper timing. The Apollo S uses strategically angled ports that direct gas rearward and laterally to minimize concussion directed at the shooter while maximizing recoil reduction.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Single-chamber muzzle brake\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 6.5 Creedmoor (6.5mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 5\/8x24 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 nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-10, bolt-action rifles chambered in 6.5 Creedmoor with 5\/8x24 threaded barrels\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ultradyne USA","offers":[{"title":"Default Title","offer_id":47943770505471,"sku":"UD10250","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1291860.jpg?v=1766599714","url":"https:\/\/doublestackstore.com\/products\/ultradyne-apollo-s-mb-6-5cm-5-8x24","provider":"Double Stack Store","version":"1.0","type":"link"}
