Crimson Trace Hardline 4-12x40mm BDC 223/5.56 Reticle Black Anodized Rifle Scope

The Crimson Trace Hardline 4-12x40mm rifle scope is built for shooters who demand reliable, durable optics without compromise. This second focal plane scope brings together tactical design and target-shooting precision in a compact package that handles everything from precision rifle work to practical shooting disciplines. The 4-12x magnification range gives you flexibility across multiple shooting distances, while the CT Custom BDC reticle is specifically calibrated for .223/5.56 ammunition—meaning holdovers and wind calls are dialed in for your cartridge from the factory.

Built from aerospace-grade aluminum with a 1-inch tube, the Hardline scope is engineered to absorb recoil and rough handling. Fully multi-coated optics deliver 90% light transmittance, keeping your sight picture sharp and bright in varying light conditions. The scope is nitrogen-purged and waterproof, so rain, snow, dust, and condensation won't degrade your glass or internal mechanics. At 3.5 inches of eye relief and roughly 15 ounces, it balances situational awareness with a manageable weight footprint—whether you're running it on an AR-15, a precision bolt gun, or anything in between.

The 1/4 MOA clicks give you fine adjustment control, and the windage and elevation ranges (55–65 MOA each) provide plenty of room for zero shifts and shooting past typical combat distances. Whether you're zeroing for 100 yards or dialing for longer work, the side parallax adjustment keeps your reticle crisp across the focal plane. This is a scope designed for shooters who want glass that works as hard as they do.

Frequently Asked Questions

Is this scope made for .223/5.56 shooting?

Yes. The CT Custom BDC reticle is specifically calibrated for .223/5.56 ballistics, so your holdovers and wind holds are built in for that cartridge. If you're running an AR-15 or other .223/5.56 platform, the reticle is already optimized for your ammunition.

What does second focal plane mean?

The reticle size remains constant relative to your eye, but its subtensions (holdover values) change with magnification. At lower power, the reticle subtends more target area; at higher power, it subtends less. This design prioritizes ease of use at your primary aiming magnification.

Can this scope handle rough handling and outdoor conditions?

Yes. The scope is constructed from aerospace-grade aluminum, nitrogen-purged, and waterproof. It's designed to absorb recoil and resist moisture, dust, and environmental damage—built for tactical and field use.

What are the adjustment ranges for windage and elevation?

Both windage and elevation offer 55–65 MOA of adjustment range, giving you plenty of room to zero and dial for extended-range shooting or to correct for different loads and atmospheric conditions.
