Crimson Trace Hardline 3-9x40mm BDC 223/5.56 Reticle Scope - Black Anodized, 1" Tube

The Crimson Trace Hardline 3-9x40mm scope is a no-compromise optic built for shooters who demand toughness and precision in a versatile package. This 1-inch tube rifle scope pairs a .223/5.56 BDC reticle with second focal plane design, making it a practical choice for AR-platform hunters, competition shooters, and tactical range work. The aerospace-grade aluminum construction absorbs real abuse, while the fully multi-coated optics and nitrogen purging keep things clear and dry—even in rough conditions. At 3 to 9 power, you get flexible magnification for everything from 100-yard sighting to mid-range precision work, without the bulk and weight of a true long-range scope.

Generously spaced eye relief (nearly 90mm) gets you back behind the scope quickly when transitions matter, and exposed turrets give you straightforward click-and-adjust zero correction at 1/4-inch per click. The BDC reticle is calibrated specifically for .223 and 5.56 ballistics, so if you're running one of the most common cartridges in America, the holdover points are already dialed in. Light transmittance runs at 90 percent, delivering a bright sight picture across the magnification range. Weighing just over 12 ounces, it won't bog down your rifle.

Whether you're building a modern sporting rifle for hunting, setting up a competition gun, or equipping a tactical trainer, the Hardline brings serious construction and practical optics to the table without demanding a precision rifle budget.
