Crimson Trace Hardline 4-12x40mm BDC Long Range Reticle Riflescope - Black Anodized, 1" Tube

The Crimson Trace Hardline 4-12x40mm BDC long range reticle riflescope is built for shooters who demand durability and precision without compromise. Whether you're dialing in shots at distance on the range or hunting across variable terrain, this scope delivers the optical clarity and rugged construction that separates quality glass from the rest. The 1-inch tube and aerospace-grade aluminum body are engineered to withstand hard use, while the second focal plane design and custom BDC reticle give you the aiming reference you need when accuracy counts.

That 4-12x magnification range keeps you flexible—low enough for quick target acquisition in unpredictable light, high enough to reach out and resolve details at distance. Three and a half inches of eye relief means you're not glued to the eyepiece, and the fully multi-coated optics deliver a bright 90% light transmission so you're not losing image quality where it matters most. The scope is nitrogen purged and waterproof, so rain, dust, or sudden weather swings won't compromise your zero or your shot.

Crimson Trace designed the Hardline line from the ground up for tactical and target shooters who live by their glass. Every spec—the one-quarter MOA click adjustments, the 55–65 MOA windage and elevation range, and the compact 14.1-inch length—reflects that mission. This is a scope that earns its place on a precision rifle.

Frequently Asked Questions

What reticle does this scope use?

The Hardline 4-12x40 features Crimson Trace's custom BDC reticle calibrated for .223/5.56, plus a MILDOT overlay. The second focal plane design places the reticle in the rear element, so it remains proportional to the target across all magnification settings.

Is this scope good for long-range shooting?

Yes. The 4-12x magnification and 40mm objective are well-suited to precision shooting at distance. The BDC reticle and 1/4 MOA adjustments give you the tool to dial and aim effectively, while the 23.6-foot field of view at 4x power helps you locate targets quickly.

What is the eye relief, and why does it matter?

This scope offers 3.5 inches of eye relief, which is generous for a tactical riflescope. That extra space lets you get back on target quickly, especially when shooting from variable positions or in training scenarios where you need to reacquire the sight picture fast.

Will this scope hold up in bad weather?

The Hardline is nitrogen purged and fully waterproof, so it resists moisture, fog, and temperature swings. The aerospace-grade aluminum tube is also designed to withstand hard use, making this a scope built for the field, not just the bench.
