  1. Boresight

    Boresight is the adjustments made to an optical firearm sight or iron sights, to align the firearm barrel and sights. This method is usually used to pre-align the sights, which makes zeroing much faster. A device called a bore sighter or collimator is used to accomplish this. It consists of an optical head and a bore-diameter arbor which is inserted into the muzzle of the rifle. The optical head is then attached to the protruding end of the rod. A grid pattern on the optical head is then used to align the sights with the barrel. Traditional boresighting, as the name suggests, involves removing the bolt and sighting down the bore of a gun to a fixed point. While the rifle is fixed in place, the scope or irons can then be adjusted to also aim at the distant object. A more modern method of boresighting is to use a laser rather than by visual inspection to illuminate the distant point. This method is preferable because it allows more movement in the gun, as the laser dot will not move relative to the barrel, and is a method of boresighting which does not require the removal of the bolt. A more advanced method of boresighting uses a collimator, an optic attachment similar to a scope sight, which fits onto the end of the barrel. Using this method, the normal sight and the collimator can be sighted to match. Most collimators have grid patterns for rechecking the zero after the barrel is sighted.
