Crimson Trace Hardline Rifle Scope - 4-12X40Mm 1" Sfp Mil-Dot

The Crimson Trace Hardline 4-12x40mm rifle scope is a rugged, no-nonsense optic built for shooters who demand reliability in the field or at the range. Constructed from aerospace-grade aluminum with a 1-inch tube, this second focal plane scope delivers the durability and optical clarity that tactical and target shooters need without excess weight or unnecessary features. Whether you're zeroing in on game, running drills downrange, or working through precision rifle applications, the Hardline's straightforward design and generous 3.5 inches of eye relief keep you focused on the shot.

The scope pairs a CT Custom BDC .223/5.56 mil-dot reticle with solid light transmission (90%) across a 23.6 ft. maximum field of view, making target acquisition quick at lower magnifications and detailed work at 12x easier. Quarter-MOA click adjustments and 55–65 MOA windage and elevation ranges give you the adjustment latitude most hunting and range scenarios demand. The scope is fully multi-coated, nitrogen-purged, and waterproof—ready for rain, fog, dust, or whatever conditions you face. At just over 15 ounces, it won't burden your rifle platform.

This is a straightforward, honest scope: no illuminated reticle, no fancy coatings or marketing speak—just proven optics engineered to hold zero and perform under real-world use. The Hardline suits hunters working moderate ranges, precision rifle competitors, and anyone who values durability and clarity over gimmicks.

Frequently Asked Questions

What rifles and calibers is the Hardline 4-12x40 compatible with?

The scope features a 1-inch tube and standard Picatinny rail mounting dimensions (2.1-inch rear, 2.5-inch front), making it compatible with any rifle with a Picatinny top rail. The CT Custom BDC .223/5.56 mil-dot reticle is optimized for those cartridges, though the scope can certainly be mounted on rifles in other calibers and zeroed accordingly.

Is the reticle illuminated?

No. The Hardline features a non-illuminated mil-dot reticle. This simplifies the design, reduces weight, and eliminates battery dependency—ideal for hunters and shooters who prefer proven, uncomplicated optics.

What's the eye relief, and is it suitable for recoil-sensitive shooting?

Eye relief is 3.5 inches, which is considered generous and allows you to position the scope comfortably on most rifles, including those with significant recoil. The substantial eye relief also speeds up target reacquisition when moving between targets.

Is the scope waterproof?

Yes. The Hardline is nitrogen-purged and fully waterproof, designed to perform reliably in rain, fog, and wet field conditions without internal fogging or moisture damage.
