Sighting in a rifle is an essential part of preparing for a hunt or shooting event. The challenge when sighting in a new scope is that the crosshairs may not be pointing anywhere near where the muzzle is pointing. Trying to sight the rifle in at this point may be time consuming and expensive due to wasted ammunition. Boresighting can simplify and speed up the process. Here are a few tips for selecting a boresight:
The History of Boresights
The oldest and simplest way of boresighting a firearm is to steady it in a gun vice or on sandbags, and then to look down the barrel toward a target. After centering the target through the barrel, you would next look through the scope and make any windage and elevation adjustments to center the crosshairs on the target.
While this method is simple and requires no additional equipment, it is not perfect. The first problem is that this method can only be used on limited firearms like single-shot and bolt action models that allow the shooter to look straight down the barrel. This method is also not as precise as more modern options.
Another option is to use a collimator and arbor or spud. This approach involves inserting the arbor or spud into the muzzle, and then sighting the scope using the collimator (a paper grid).
Laser boresights are the newest option for boresighting a firearm, and are available in several styles from different manufacturers. Laser boresights work by projecting a laser beam from the muzzle toward a target. Once the laser dot is on the target, it is easy to adjust windage and elevation on the scope. Options for laser boresights include models that mount in the muzzle, models that attach to the outside of the barrel magnetically, and models that resemble a cartridge and are chambered in the gun.
Whichever boresight option you choose, it is important to remember that boresighting is a tool to facilitate sighting in your firearm. It will not sight the gun in by itself, but is instead a first step. Precise sighting requires firing live ammunition at a target.
Reasons to Consider Our Boresights
Open boresighting is preferred by some shooters because of its simplicity. Magnetic and cartridge-style boresights are preferred by many shooters who object to inserting a spud or arbor into the muzzle of their firearm.
