{"product_id":"lbe-750-gas-block-w-rail-blk","title":"LBE Unlimited .750 Gas Block with Rail – AR-15 Platform","description":"\u003cp\u003eThe LBE Unlimited .750 Gas Block with Rail is a low-profile gas block that adds a short Picatinny rail section forward of the gas tube, giving you a mounting point for flip-up front sights, lights, or other accessories on free-float handguard builds. This replaces your standard A-frame front sight base or low-profile gas block when you want the clean lines of a free-float rail but still need a front sight or accessory mount. It's a practical solution for shooters who want modularity without running a full-length top rail.\u003c\/p\u003e\u003cp\u003eMachined from steel with a black finish, this gas block is designed for .750-inch diameter gas journals, the standard size on most mid-length and carbine-length AR-15 barrels. Installation requires removal of the existing gas block and pinning or set screws to secure the new block in place—some mechanical aptitude and proper tools are required. Confirm your barrel's gas journal diameter before ordering.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Gas Block with Picatinny Rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 platform rifles with .750\" diameter gas journals\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Journal Diameter:\u003c\/strong\u003e .750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Requires removal of existing gas block; mechanical knowledge and proper tools recommended\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas block with integrated rail section (hardware may vary; confirm with manufacturer)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LBE Unlimited","offers":[{"title":"Default Title","offer_id":47943859339519,"sku":"LBARGBR-UH","price":28.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2867714.jpg?v=1766604041","url":"https:\/\/doublestackstore.com\/products\/lbe-750-gas-block-w-rail-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
