The body is machined from \u003cstrong\u003ebrass\u003c\/strong\u003e to the actual chamber dimensions of the .40 Smith \u0026amp; Wesson cartridge, so the unit drops in like a snap-in dummy round and projects a \u003cstrong\u003ered laser\u003c\/strong\u003e downrange. That lets you quickly and accurately dial in iron sights, red dots, and pistol optics before burning a single round of live ammunition.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eBecause the boresight is caliber-specific rather than universal, the brass body seats precisely in the .40 S\u0026amp;W chamber for a more representative point of aim and a much closer match to live-fire impact than loose universal-fit units. Beyond range-day sight-in, the SM39016 doubles as a useful dry-fire training aid for \"quick draw\" drills, trigger-pulls, and draw-to-target practice at home.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe unit ships complete with a \u003cstrong\u003ecarrying case\u003c\/strong\u003e to protect the brass body and laser module in your range bag, \u003cstrong\u003ethree AG3 button-cell batteries\u003c\/strong\u003e for immediate use, and operating instructions. With batteries installed, simply chamber the boresight like a round, close the action, and walk your sights to the laser to confirm zero before heading to the range.\u003c\/span\u003e\u003c\/p\u003e","brand":"Sightmark","offers":[{"title":"Default Title","offer_id":55100537176386,"sku":"8154","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_9ea6abb8-4729-4ca7-8267-52d0e01c2c55.png?v=1784790491","url":"https:\/\/centerfiresystems.com\/products\/sightmark-sm39016-boresight-red-laser-40-s-w-brass","provider":"Centerfire Systems","version":"1.0","type":"link"}
