{"product_id":"ultradyne-pegasus-mb-5-56-1-2x28","title":"Ultradyne USA Pegasus Muzzle Brake 5.56 NATO 1\/2x28 – AR-15 Pattern Rifles","description":"\u003cp\u003eThe Ultradyne Pegasus Muzzle Brake redirects propellant gases to reduce felt recoil and muzzle rise during rapid fire. Designed for 5.56 NATO chamberings, this brake uses precisely angled ports to push the muzzle forward and downward, keeping your sights on target for faster follow-up shots. Shooters running competition stages or high-volume training will notice the difference in split times and shooter fatigue.\u003c\/p\u003e\u003cp\u003eThe Pegasus installs on any AR-15 barrel with standard 1\/2x28 threads. Constructed from heat-treated steel with a black nitride finish for corrosion resistance and durability under sustained fire. Timing is achieved via included shims. No crush washer required. Check local and state regulations before installation—some jurisdictions restrict muzzle devices on semi-automatic rifles.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Muzzle Brake\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\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-15 pattern rifles with 1\/2x28 threaded barrels\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ultradyne USA","offers":[{"title":"Default Title","offer_id":47943771783423,"sku":"UD11010","price":139.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1292106.jpg?v=1766599858","url":"https:\/\/doublestackstore.com\/products\/ultradyne-pegasus-mb-5-56-1-2x28","provider":"Double Stack Store","version":"1.0","type":"link"}
