When no wimpy red dot will do, head to the Bushnell Big D.

It’s no lie that electro optics have been getting smaller, lighter and tougher. Still, something can be said for big, beefy optics. They have a certain air of confidence about them that no matter what hits them, they’ll keep working. And one of the biggest and baddest (in a good way) red dots to come along is the Bushnell Big Dot sight.

The Bushnell Big D red dot sight harkens back to earlier days when dots were evolving. But unlike its underpowered and optically challenged predecessors, Bushnell’s stout fighter features a multi-­coated 37mm objective lens that provides the widest field of view of any electronic unit and packs up to 50,000 hours of run time from one battery.

At just over 4 inches long and 2 inches wide, the 10-­ounce Big D’s strength is apparent in its one-­piece base and housing that’s set just at the right height for use on an AR. There’s no way you’ll knock this out of whack. Even the spring-­loaded lens caps are thicker plastic.


Where the Big D offers shooters and law enforcement the brute strength to absorb hard knocks, it’s still a basic red dot with six dot intensity levels. The quality and illumination of the dot are excellent.


So, if you’re looking for a red dot that can go the distance through the toughest terrain, storm a bunker or survive the recoil of a heavy AR-­10, the Bushnell Big Dot would be a smart choice.

Shooting 600 Yards with .300 Blackout

The .300 Blackout cartridge was developed to provide greater effectiveness than a 9mm at short and medium ranges when fired from a short-barreled suppressed firearm. Just because the cartridge wasn't designed to go long doesn't mean Rifles & Optics Editor Tom Beckstrand won't take it there, using a large-format pistol, no less. Armed with SIG Sauer's 9-inch-barreled MCX Virtus Pistol loaded with Black Hills' 125-grain TMK ammunition, Beckstrand attempts to ring steel at 600 yards with help from Hornady's 4DOF ballistic calculator in this segment of “Long Range Tech.”
