{"product_id":"nightforce-30mm-top-half-ring-w-level-bubble","title":"Nightforce 30mm Top Half Ring w\/Level Bubble","description":"\u003cp\u003eCant is the error nobody sees themselves make. If the rifle is rolled a few degrees off vertical, your elevation dial no longer moves the bullet straight up — part of it goes sideways, and the further you dial, the further left or right you push. At close range it hides inside the group. At distance it becomes a miss you will blame on wind.\u003c\/p\u003e\u003cp\u003eThis part solves it by replacing the top half of a ring you already own with one carrying an integrated bubble. That is the design decision worth understanding: the level is not bolted onto the rail out ahead of the scope, and it does not consume rail space you might want for a rangefinder or a night vision clip-on. It sits on the tube, in the lower edge of your vision as you settle behind the glass, where you will actually glance at it before the shot rather than after.\u003c\/p\u003e\u003cp\u003eBecause it is a direct top-half swap, installation is a matter of removing the existing top ring and fitting this one — no re-zeroing the rifle, no shimming, no repositioning the scope in the rings.\u003c\/p\u003e\u003cp\u003eThis is the 30mm version. Tube diameter has to match your scope, and the screw pattern has to match the ring base it is mating to, so check both before ordering — a 30mm level will not close around a 34mm tube, and a 4-screw top will not line up on a 6-screw bottom.\u003c\/p\u003e","brand":"Nightforce","offers":[{"title":"Default Title","offer_id":43019618189383,"sku":"A128","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8250\/4519\/files\/nightforce_ring_cap_bubble_level__57208.jpg?v=1785358334","url":"https:\/\/extremestore.us\/products\/nightforce-30mm-top-half-ring-w-level-bubble","provider":"The Extreme Store","version":"1.0","type":"link"}
