{"product_id":"adv-tech-750-low-profile-gas-block","title":"ATI Outdoors ADV Tech .750 Low Profile Gas Block – AR-15 Platform","description":"\u003cp\u003eThe ATI Outdoors ADV Tech .750 Low Profile Gas Block is a direct replacement for standard-diameter front sight base assemblies on AR-15 platform rifles. Designed to sit beneath free-float handguards, this low-profile block redirects barrel gas into the gas tube without the added height or weight of a traditional front sight tower. Upgrading to this style opens up options for extended rail systems and provides a cleaner barrel profile for optics-focused setups.\u003c\/p\u003e\u003cp\u003eConstructed from steel with a black oxide finish for corrosion resistance, this gas block features set screw mounting for secure installation on .750-inch diameter gas port journals. Installation requires removal of the existing front sight base, proper alignment of the gas port, and securing the block with included set screws. A gunsmith or experienced builder is recommended to ensure correct gas system function and headspace safety.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Low Profile Gas Block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 rifles with .750\" barrel diameter at gas port\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 Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Professional Recommended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas block, set screws\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATI Outdoors","offers":[{"title":"Default Title","offer_id":47943511015679,"sku":"ADVA8100050","price":20.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1240130.jpg?v=1766581740","url":"https:\/\/doublestackstore.com\/products\/adv-tech-750-low-profile-gas-block","provider":"Double Stack Store","version":"1.0","type":"link"}
