The Crimson Trace Hardline Pro 3-12x42mm rifle scope is a versatile second focal plane optic built for shooters who demand reliability across tactical, hunting, and precision target work. This scope brings together a robust 30mm aerospace aluminum tube, intelligent magnification range, and purposeful design choices that keep your focus on the shot—not on gear limitations. Whether you're working steel at distance or hunting mid-range game, the Hardline Pro delivers the optical quality and durability needed in the field.
Crimson Trace engineered this scope from the ground up with the experienced tactical and target shooter in mind. The scope uses fully multi-coated optics and nitrogen purging to cut glare, maintain clarity in variable light, and resist the punishment of recoil and harsh weather. Its exposed turrets invite quick field adjustments, while the adjustable side parallax dial lets you dial in your precise distance for crisp images at any magnification. The CT Custom MR1-MOA reticle gives you clean aiming reference without excess visual noise, and 1/4 MOA clicks let you dial in corrections with fine precision.
At 20.5 ounces and 13.1 inches long, the Hardline Pro balances optical capability with practical carry weight. The 3.5-inch eye relief plays well with modern rifle setups, and the scope's 85 MOA elevation and windage range covers most hunting and mid-range shooting applications. With 90% light transmittance and green multi-coated glass, you get the optical fidelity to trust your ballistics out to distance.
| Magnification | 3-12x |
| Objective Lens Diameter | 42mm |
| Tube Diameter | 30mm |
| Focal Plane | Second |
| Reticle | CT Custom MR1-MOA |
| Eye Relief | 3.5 inches |
| Click Value | 1/4 MOA |
| Elevation Range | 85 MOA |
| Windage Range | 85 MOA |
| Side Parallax | Adjustable |
| Zero Stop | No |
| Illumination | None |
| Light Transmittance | 90% |
| Lens Coating | Green Multi-Coated |
| Tube Material | Aerospace Aluminum |
| Scope Length | 13.1 inches |
| Weight | 20.5 ounces |
| Rear Mounting Length | 2.1 inches |
| Front Mounting Length | 2.3 inches |
| Maximum FOV | 37.5 feet |
| Minimum FOV | 9.5 feet |
In a second focal plane scope like the Hardline Pro, the reticle stays the same size no matter what magnification you dial in. That means your aiming point doesn't subtend differently at 3x versus 12x—handy for tactical work and hunting where you want consistent reference without mental math. The tradeoff is that ranging with the reticle gets less precise at lower magnifications, but for most field work this design is intuitive and reliable.
The Hardline Pro's 3.5-inch eye relief and 30mm tube work with most modern tactical and hunting rifles, including AR platforms and standard bolt rifles with Picatinny rails. Front and rear mounting lengths are 2.3 inches and 2.1 inches respectively, so verify your rifle's rail spacing before mounting. You'll need standard 30mm rings or a Picatinny-compatible mounting system.
No—the Hardline Pro uses a non-illuminated CT Custom MR1-MOA reticle. The reticle is designed to work in typical daylight and low-light conditions using the multi-coated glass and high light transmittance (90%), making it suitable for dawn, dusk, and overcast hunting or tactical scenarios without battery concerns.
Parallax is the apparent movement of the reticle against the target when you shift your eye position behind the scope. Adjustable side parallax (sometimes called a parallax turret) lets you dial out this effect at specific distances, giving you a perfectly crisp image at your working range. This is especially valuable for precision target shooting or when accuracy at a known distance is critical.
