{"product_id":"nightforce-34mm-top-half-ring-w-level-bubble-4-screw","title":"Nightforce 34mm Top Half Ring w\/Level Bubble, 4 Screw","description":"\u003cp\u003eA bubble level earns its place on a rifle the moment you start dialing elevation for distance. Rifle cant tilts the entire adjustment axis, so a turret correction that should lift the bullet straight up instead pushes it diagonally — and the error scales with how much you dial. Shooters who cannot explain their horizontal stringing at distance are very often looking at a cant problem rather than a wind problem.\u003c\/p\u003e\u003cp\u003eRather than adding hardware, this replaces the top half of a ring you already have. The bubble ends up on the scope tube itself, low in your sight picture, which is the difference between a level you check and a level you own. Rail-mounted levels sit forward and out of the natural line of sight, and they compete for the same rail real estate as a rangefinder or clip-on.\u003c\/p\u003e\u003cp\u003eThe swap does not disturb the scope's position in the rings, so your zero survives the installation.\u003c\/p\u003e\u003cp\u003eThis is the 34mm, 4-screw version. Four-screw is the standard Nightforce clamping arrangement and is entirely sufficient for normal centerfire recoil — fewer fasteners to torque and fewer to keep track of in the field. The screw count is not a preference, though: it must match the ring bottom you are mating to. If your rings are 6-screw, order the 6-screw version instead.\u003c\/p\u003e","brand":"Nightforce","offers":[{"title":"Default Title","offer_id":43019618353223,"sku":"A270","price":80.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8250\/4519\/files\/nightforce_ring_cap_bubble_level__72916.jpg?v=1785358340","url":"https:\/\/extremestore.us\/products\/nightforce-34mm-top-half-ring-w-level-bubble-4-screw","provider":"The Extreme Store","version":"1.0","type":"link"}
