{"product_id":"sme-sight-rite-chamber-cartridge","title":"SME Sight-Rite Chamber Cartridge Laser Bore Sighter","description":"\u003cp\u003eThe SME Sight-Rite Chamber Cartridge is a laser bore sighting system designed to help shooters achieve a working zero before visiting the range. Each cartridge is precision-machined from brass to exact chamber tolerances for the relevant calibre, seating like a dummy round for a precise, wobble-free fit. A high-output laser beam projects down the barrel from the muzzle end, allowing the user to align a scope or open sights with a target at a chosen zeroing distance without firing a shot. The laser comes factory-aligned so it is ready to use without any adjustment, and batteries are supplied in the box. By establishing a rough zero on the bench before live firing, the Sight-Rite system reduces the number of shots needed to achieve a final zero — saving both time and ammunition. The calibre-specific brass construction gives consistent alignment shot to shot and avoids the wobble associated with muzzle-insert bore sighters.\u003c\/p\u003e","brand":", Express_Shipping , Export_Block , LS-RM Default","offers":[{"title":"Default Title","offer_id":45030960693448,"sku":"324212","price":39.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0071\/8906\/9860\/files\/FjIdwfmQ4oqg1CzDbjFA4FzS9LvX7k6R-24.jpg?v=1774020332","url":"https:\/\/www.bushwear.co.uk\/products\/sme-sight-rite-chamber-cartridge","provider":"BushWear","version":"1.0","type":"link"}
