Save time, money and frustration by getting on paper with your first shot. Our professional laser boresighter is machined to the highest standards of S.A.A.M.I. specifications to ensure the highest accuracy. Place the boresighter into your chamber and close the breech. The laser will automatically turn on and be centered in the barrel. It projects a straight laser beam allowing precise optical adjustments. This boresighter is perfect for the range and ensuring your gun is still zeroed in after travel. The laser unit fits the .223 chamber. By sliding the unit into additional sleeves (sold separately), you can use it in most popular calibers. Made in USA.
