{"product_id":"real-avid-lug-lok-upper-vise-block","title":"Real Avid Lug-Lok Upper Vise Block","description":"Traditional clamp-style upper blocks fit poorly and can exert enough inward pressure to damage the receiver when applying torque to a barrel nut or flash suppressor. That’s bad design. So, we designed an upper block that leverages the strongest part of the gun – the barrel lugs inside the star chamber. The Lug-Lok is precision machined and precisely fits into all Mil-Spec uppers. It mates perfectly with the barrel lugs, while allowing you to rotate the upper to be able to work on different sides. There are 2 vise pins that allow you to hold the upper at multiple working angles and prevent unwanted rotation during high torque application. The lock knob keeps Lug-Lok seated into the barrel lugs. The result – the safest, easiest and smartest way to lock down an AR15 or AR10 upper into a bench vise. Choose AR10 or AR15 platform below.","brand":"Real Avid","offers":[{"title":"Default Title","offer_id":54054556860729,"sku":"RAV-AVAR10LLVB","price":134.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2538\/6041\/files\/RAV-AVAR10LLVB.png?v=1784165030","url":"https:\/\/www.guncycle.com\/products\/real-avid-lug-lok-upper-vise-block","provider":"GunCycle","version":"1.0","type":"link"}
