DetailsThe Sweany SITE-A-LINE is the original and most accurate boresighting instrument used by hunters, gunsmiths and military ordinance groups the world over. The square grid reticle version is not recommended for use with ironsights or high power scopes. For those applications, please use our diagonal crosshair reticle Site-A-Line. SITE-A-LINE saves up to 80% time in locating front sight heights, installing ramps, scope mounts, receiver sights, checking barrel bedding, action bedding, barrel movement and inelling stocks as well as readjusting rifle and pistol sights. Through the use of spud adaptors, one SITE-A-LINE fits all makes and models of firearms. Spuds are precision ground to fit the minimum bore sizes defined by arms manufactures and given hard chrome plating to resist wear and corrosion. They are generally interchangeable in several calibers in each bore size. SITE-A-LINE will withstand several times the abuse the normal scope sight will endure. It is completely at home under severe hunting and weather conditions. To order, add the SITE-A-LINE to your cart, and then choose the spud that fits your bore from our short spuds, long spuds or shotgun spuds. General instructions for using the SITE-A-LINE can be found here. Also check out our FAQ.
