{"product_id":"kak-retro-duckbill-fh-1-2x28","title":"KAK Industry Retro Duckbill Flash Hider 1\/2x28 – AR-15\/M16","description":"\u003cp\u003eThe KAK Industry Retro Duckbill Flash Hider is a faithful reproduction of the three-prong flash suppressor used on early M16 rifles. This muzzle device redirects muzzle flash away from the shooter's line of sight while maintaining the classic profile of Vietnam-era service rifles. The duckbill design features three forward-facing prongs that break up and disperse combustion gases, reducing visible signature during low-light shooting.\u003c\/p\u003e\u003cp\u003eMachined from steel with a phosphate finish, this flash hider threads directly onto standard 1\/2x28 TPI barrels found on .223\/5.56 rifles. Installation requires a crush washer or shim kit for proper timing and a standard armorer's wrench. The design allows full use of standard AR-15 cleaning rods through the center port. Ideal for builders seeking period-correct aesthetics or shooters who prefer the proven performance of the original three-prong pattern.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Three-Prong Flash Hider\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e .223\/5.56mm\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 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M16, and similar .223\/5.56 rifles with 1\/2x28 muzzle threads\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KAK Industry","offers":[{"title":"Default Title","offer_id":47942774128895,"sku":"KAK1-2-28-DUCKBILL","price":13.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/4479417.jpg?v=1766570732","url":"https:\/\/doublestackstore.com\/products\/kak-retro-duckbill-fh-1-2x28","provider":"Double Stack Store","version":"1.0","type":"link"}
