Vortex Crossfire II 1Inch 6-18×44 AO Dead-Hold BDC

Product Description

The Vortex Crossfire II 6-18×44 AO Dead-Hold BDC is a variable magnification riflescope designed for hunters and precision shooters who need holdover reference points at extended range. The adjustable objective allows you to fine-tune parallax correction as distance changes, keeping your target sharp and your reticle accurate from close range out to several hundred yards.

This optic features a 1-inch main tube and uses the Dead-Hold BDC reticle, which provides multiple aiming points below center crosshair for bullet drop compensation. That makes it well-suited to varmint hunting, predator control, and any application where you need repeatable long-range performance without dialing elevation adjustments for every shot.

The 6-18x magnification range gives you flexibility. Use the lower end for scanning or closer shots where field of view matters, then dial up to 18x when you need to resolve small targets at distance or verify a clean hold before the trigger breaks.

Understanding the Dead-Hold BDC Reticle

A BDC reticle—bullet drop compensator—gives you a vertical ladder of reference points calibrated to compensate for gravity’s effect on a bullet in flight. The Dead-Hold BDC uses hashmarks and circles below the center crosshair, each representing a specific distance increment based on typical centerfire rifle velocities.

Instead of holding over and guessing, you place the appropriate hashmark on your target and send the shot. The system works best when you know your load’s trajectory and confirm your zero at a known distance, then verify which hashmark corresponds to your real-world drops at 200, 300, 400 yards and beyond.

This approach is faster than dialing turrets in the field and keeps you ready for quick follow-up shots or multiple targets at varying ranges during a single outing.

What the Adjustable Objective Does

Parallax is the apparent shift of your reticle against the target when your eye moves behind the scope. At higher magnifications and longer distances, uncorrected parallax degrades precision and makes it hard to know exactly where your shot will land.

The adjustable objective on the Crossfire II 6-18×44 AO lets you dial out parallax by matching the focus setting to your target distance. Turn the AO ring on the objective bell until the target image is sharpest and the reticle stays locked on the same point no matter where your eye sits behind the eyepiece. This becomes critical at 12x and above, where even small optical errors show up as misses on paper or game.

Mounting and Ring Considerations

The Crossfire II uses a 1-inch main tube, so you need rings with 1-inch inside diameter. This tube size is common on hunting rifles and has been the standard for decades, which means ring selection is broad and affordable compared to 30mm or 34mm tubes.

Ring height depends on your rifle’s action type, stock comb height, and whether you have a raised cheekpiece or need clearance for a large objective bell. A 44mm objective requires medium or high rings on most bolt-action rifles to prevent the bell from contacting the barrel. If you’re unsure which height works for your setup, call 817-393-4000 and we’ll walk through the measurements with you.

Frequently Asked Questions

Q: What magnification range does the Vortex Crossfire II 6-18×44 AO offer?

A: The Vortex Crossfire II 6-18×44 AO offers a magnification range of 6x to 18x. Lower magnification provides a wider field of view for target acquisition and close to mid-range work, while 18x delivers the resolution needed for precise shot placement at longer distances or when varmint hunting.

Q: What is the Dead-Hold BDC reticle and how does it work?

A: The Dead-Hold BDC reticle is a bullet drop compensator design that features hashmarks and circles below the center crosshair, each representing holdover points for different distances. You place the appropriate mark on your target based on range, allowing faster shots without dialing turret adjustments. The system requires you to know your load’s trajectory and confirm which marks correspond to your actual drops.

Q: What does AO mean on this riflescope?

A: AO stands for adjustable objective, a ring on the objective bell that lets you dial out parallax by matching the focus to your target distance. This keeps the reticle and target image in the same optical plane, preventing apparent reticle movement and ensuring precise aiming at higher magnifications and longer ranges.

Q: What size scope rings do I need for a 1-inch tube?

A: You need scope rings with a 1-inch inside diameter to fit the Crossfire II’s main tube. Ring height—low, medium, or high—depends on your rifle’s action, stock design, and objective bell clearance. For a 44mm objective on most bolt-action rifles, medium or high rings are typically required to prevent contact with the barrel.

Q: Can I use the Vortex Crossfire II 6-18×44 for long-range shooting?

A: Yes, the Crossfire II 6-18×44 AO Dead-Hold BDC is well-suited for long-range shooting, especially when you verify your BDC holdovers against your specific load and rifle. The 18x top-end magnification and adjustable objective let you resolve targets clearly and eliminate parallax error at extended distances, making it a solid choice for precision work beyond 300 yards.

Q: How do I order or ask questions about this riflescope?
