Just because we’re used to doing something a certain way doesn’t mean it can’t be done better. That’s how just about every advancement, ever, in firearms design came about—someone rethinking the normal. And that is spreading over to the world of optics these days, with green visual elements replacing red-colored elements. That’s the key feature behind MCG Tactical’s new Boar boresighter; it takes the normal red dot used for such equipment and replaces it with green.

A basic boresighter
There are two types of boresighters on the market, and they both work under the same basic principle. They shine a laser in the direction your gun’s barrel is aiming, where, in theory, your bullet would impact if you fired a shot. With your firearm on a steady surface, you can move your optic’s aiming point to cover where the laser dot is sitting on the target, getting you very close to confirming a zero.
One kind of boresighter uses a dummy cartridge to hold the laser. This means you have to have adapters for different chambers, and perhaps multiple boresighters to fit multiple firearms.
The other style of laser boresighter is placed in the firearm’s muzzle, with a spacer that’s adapted to hold it square and true. These boresighters are generally adaptable to a wider range of firearms with less fuss, and that’s the arrangement behind MCG’s Boar boresighter.
Going green
The MCG Boar boresighter uses a green laser instead of the old-school red lasers that were much more common in the past. The green light is much more easily seen than a red light, says MCG, a claim we also hear from reflex sight manufacturers, who increasingly offer green dots along with red dots. MCG claims visibility with their system can be as much as 50 times easier to see than a red laser.
