The three-screw clamp design distributes clamping force evenly around the barrel, reducing the risk of movement under sustained fire compared to traditional set-screw designs. This gas block is built for shooters upgrading to free-float handguards who need a reliable, low-profile gas system that won't interfere with handguard installation.\u003c\/p\u003e\u003cp\u003eMachined from steel with a black finish, this gas block sits flush under most free-float handguards and maintains proper gas port alignment during installation and use. The three-screw clamp design simplifies installation—no dimpling or permanent barrel modification required, though a small amount of red Loctite is recommended for secure mounting. Suitable for experienced builders comfortable with torque specifications and gas system alignment.\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 with .625\" diameter barrel journal\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\u003eInstallation:\u003c\/strong\u003e Drop-In (mechanical skill required for proper torque and alignment)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e 3-Screw Clamp Design\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Faxon Firearms","offers":[{"title":"Default Title","offer_id":47937886028031,"sku":"FXGB-LP-625-3","price":34.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/4962796.jpg?v=1766499163","url":"https:\/\/doublestackstore.com\/products\/faxon-3-screw-625-low-pro-gb-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
