MCG Tactical Has A Green Solution For Boresighting

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.


Sighting in @ TFB:

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.

They also ship their laser boresighter with a set of adapters that will fit a wide range of bore diameters, from .17-caliber to as wide as a 12 gauge. The Boar boresighter is compatible with just about any firearm, and you can check your optic’s zero at home, without loading up your vehicle and heading to the gun range (or the back 40, depending on where you live). For those who live far away from a range, this could be a valuable time-saver, and maybe a money-saver too.

It charges by USB and lasts for about 3.5 hours of runtime, far more than you’d ever need.

Pricing right now is a $55 sale (54% off), with free shipping and handling from Texas. You have a 60-day money-back guarantee, too. See more deets at MCG’s website here.

    There is no way to true this the way it's designed. Regardless of adapters used, there is just no easy way to true it as the ads portend to express. I only paid less than $14 for mine brand new, but had I paid $55, I'd be more perturbed. At least at the $14 that I paid, I don't mind spending more time truing it than the manufacturer claims.

    I have ordered this and replaced it twice through the seller. In all three cases, it has come with multiple of the 20 and 12 gauge spacers, and nothing for the 9mm/.380/.38. Three tries and all have been missing the parts. It seems to work well with the 10mm, but the fact that one of the most common sizes has been missing from three kits is troubling.
