TruGlo OPTI-Speed 1-4x24mm Illuminated Red BDC Scope, Matte Black Anodized, 30mm w/Rings

The TruGlo OPTI-Speed 1-4x24mm illuminated red BDC scope is purpose-built for modern crossbow hunters who demand accurate, fast target acquisition in variable light. This 30mm tube scope combines a glass-etched reticle with red illumination to keep your sight picture sharp whether you're glassing thick timber at dawn or picking apart shadows in brush. The calibrated BDC reticle handles the ballistics so you don't have to—compensating for bolt drop across the critical 20–70 yard hunting range.

What sets the OPTI-Speed apart from generic crossbow scope bundles is the speed-calibration system. Unlike one-size-fits-all optics, this scope's reticle and target image scale to match your crossbow's velocity, anywhere from 215 to 450 feet per second. A simple dial adjustment lets you dial in your bow's speed, and the reticle automatically scales so your hold-overs stay true. That means whether you're running a light, fast setup or a heavier crossbow, your ballistics hold without guesswork. The illuminated reticle can run bright in low light or be dialed down in daylight, and works equally well with or without the red dot activated depending on your target and conditions.

Build quality matters in the field. The scope is waterproof and fog-proof with nitrogen gas filling to keep internal optics clear through temperature swings and wet weather. Fully multi-coated lenses deliver bright, high-contrast glass so you see every detail of your target. Adjustments are solid and repeatable via leaf-spring click mechanisms for windage and elevation in half-minute-of-angle increments. The scope ships with 30mm Weaver-style rings and a CR2032 battery, so you're ready to mount and hunt.

Frequently Asked Questions

Will this scope work with my crossbow's speed?

Yes. The OPTI-Speed's speed-calibration dial lets you adjust for crossbow velocities between 215 and 450 feet per second. Once you dial in your bow's speed, the reticle and target image scale automatically so your hold-overs remain accurate across the 20–70 yard range.

Do I need to use the red illumination?

No. The glass-etched reticle is fully usable with the light off. You can dial the illumination up or down with the adjustable rheostat brightness control depending on light conditions and target color. Many hunters prefer to run it bright in low light and dim or off in daylight.

What rings are included?

The scope comes with Weaver-style 30mm rings, so you can mount it directly to any Weaver or Picatinny rail on your crossbow without buying additional ring sets.

Is this scope waterproof?

Yes. The OPTI-Speed is waterproof and fog-proof, filled with nitrogen gas to prevent internal fogging across temperature changes and in wet weather conditions.
