Crimson Trace Corp. (CTC), the company that pioneered lasergrips, has gotten into the riflescope business. For years CTC has been adding products to its line, including trigger-guard-mounted lasers, frame-mounted lasers, flashlights, and a lot more. Now the company has introduced a line of variable-power riflescopes with 30mm and 34mm single-piece, aircraft aluminum tubes. Magnification ranges go from 1-24X to 5-25X.

There are tactical scopes, and there are sporting models. The tactical scopes feature MIL adjustments, while the sporting models are MOA. Several models are available with illuminated reticles, and all are fog-, shock-, water-, dust-, vibration-, and recoil-proof.

This scope, the Crimson Trace CTL-3420 4-20X 50mm, features Crimson Trace’s LR1-MIL reticle located in the first focal plane, zero reset turrets, side parallax adjustment, a focus range of from 10 yards to infinity, unique EZ Mount Leveling indicator lines on the sides of the tube, and fully multi-coated Japanese ED glass. It’s nitrogen-purged and O-ring sealed, and it is covered by a full lifetime warranty.


The scope’s custom-designed, glass-etched LR1-MIL reticle is illuminated and has 11 brightness settings (including three night settings). It is powered by a CR2032 battery, and it’s what you would call a “Christmas tree” type of reticle. It’s unique in that there is no upper crosshair. Because it’s located in the first focal plane, it scales to provide the correct ballistic points regardless of the magnification setting, plus it can be sighted-in on any magnification. And it’s part of CTC’s “Free Batteries for Life” program.

The CTL-3420 4-20X 50mm’s magnification range runs from 4X to 20X, and it’s 14.6 inches long and weighs 30.2 ounces. This model has 100 MILs of elevation adjustment and 60 MILs of windage. The field of view is 28.9 feet at 100 yards at 4X, and eye relief is 3.7 inches.

CTC has developed a thorough protocol for ensuring that its riflescopes are robust. The protocol includes extreme environmental testing, excessive drop testing, and severe recoil testing.

MSRP: $1,099
