This combo ships with the gas block and gas tube \u003cstrong\u003epre-assembled and pinned together\u003c\/strong\u003e, cutting installation time and getting the upper together faster than sourcing and fitting each component separately.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe \u003cstrong\u003elow profile gas block\u003c\/strong\u003e is machined from \u003cstrong\u003esteel\u003c\/strong\u003e with a \u003cstrong\u003eblack finish\u003c\/strong\u003e and is sized for the standard \u003cstrong\u003e.750\" gas journal\u003c\/strong\u003e found on most AR-15 barrels. Its low profile footprint keeps the unit tight to the barrel so it tucks cleanly under free-float handguards, drop-in handguards, and slim M-LOK and KeyMod rails without clearance issues. The included \u003cstrong\u003emid-length gas tube\u003c\/strong\u003e is matched to mid-length gas system barrels, providing reliable cycling and smooth operation for a standard rifle or pistol build.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eInstallation is straightforward for anyone familiar with the AR-15 upper: the assembled unit seats into the gas block journal on the barrel, the tube routes through the upper receiver gas port, and the included \u003cstrong\u003epin\u003c\/strong\u003e locks the gas block to the barrel so it stays put under recoil and field use. This is a budget-friendly, no-frills solution for builders assembling a fresh AR-15, replacing worn gas system components on an existing rifle, or simply wanting a pre-pinned combo for a quicker build.\u003c\/span\u003e\u003c\/p\u003e","brand":"TacFire","offers":[{"title":"Default Title","offer_id":55063786193218,"sku":"188296","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_e8a481ab-187d-4c43-bf23-80893b439409.png?v=1784735788","url":"https:\/\/centerfiresystems.com\/products\/tacfire-mar011-750-low-profile-gas-block-and-mid-length-gas-tube-combo-pinned","provider":"Centerfire Systems","version":"1.0","type":"link"}
