What it is

The Crossfire II is Vortex's entry riflescope line, and this 3-9x40 is its definitive configuration: the classic do-everything hunting setup. Second focal plane, capped 1/4 MOA turrets, fixed 100-yard parallax, 14.8 oz. It is deliberately simple. What made it the segment benchmark is that the basics are executed properly at a price where competitors historically cut corners: real zero retention, usable glass and a warranty with no fine print.

The Crossfire II line, and where the 3-9x40 fits

Vortex sells the Crossfire II as a full line, not a single scope: it spans a 1-4x24 low-power variable, the 2-7x32 (a favorite for rimfire and scout builds), this 3-9x40, and longer 4-12x44 and 6-18x44 configurations, with V-Plex or Dead-Hold BDC reticles. The 3-9x40 is the one most buyers land on because it is the classic do-everything hunting magnification: enough zoom for a deer at 250 yards, a wide field of view up close, and the lowest price of the bunch. Want more reach for open country? The 4-12x44 is the natural step up; for a rimfire or truck gun, the 2-7x32 is lighter. This review covers the 3-9x40, the volume seller.

Glass: bright where it counts, honest at the edges

From 3x to about 6x, the fully multi-coated glass is the star of the price class. Owners repeatedly compare it to scopes costing multiples more: one long-term owner called his "just as clear as my more expensive Leupold". Push toward the maximum 9x and the budget optics physics show up: edges soften and high-contrast scenes (dark target, bright snow) can show color fringing. That ceiling matters for target shooters; for a deer at 150 yards it does not.

Handling: the eye box is the quiet superpower

Eye relief runs 3.8 to 4.4 inches with a generous eye box at low power, which does two real jobs: it keeps the ocular off your brow under recoil, and it lets you snap the rifle up and find a full image without a perfect cheek weld. A verified owner running it on a hard-recoiling rifle put it simply: "good eye relief of 3 plus inches as well as ease of acquisition of target unlike many of the higher priced scopes."

Durability and tracking

The single-piece aluminum tube is nitrogen purged and O-ring sealed, and the record on zero retention is strong: independent field testing ran 150 rounds of .308 with box tests and no zero shift, and owners report the same on .30-06 and .45-70 platforms. The capped turrets track for sight-in purposes but click softly; this is a zero-and-forget scope, not a dialing instrument, and Vortex does not pretend otherwise.

What owners say (231 verified reviews, 4.7/5 on OpticsPlanet)

“Great scope, regardless of the price, but very good value. Clarity and eye relief are fantastic.”

jpfadden, verified owner (NH)

“Great scope was just what I needed for my 22LR and I can use it on several other rifles as well.”

Ronald S. Parks III, verified owner (CO)

“Vortex makes a great not expensive scope… good scope for the money” (listing “not competition shooting equipment” as the con, which matches our read exactly)

Price history: $118.79 is a genuinely good price

List price is $189.99 (earlier MSRPs ranged to $239.99 by reticle). The typical street price has been around $149, with holiday sales commonly hitting $129 and rare clearance floors near $109 to $119. Today's $118.79 for the in-stock V-Plex model sits at the bottom of that historical range. The Dead-Hold BDC variant lists at $126.99 but has run backordered at OpticsPlanet.

Trade-offs, plainly

• Glass softens at the edges toward 9x with some color fringing in harsh light: treat it as a superb 3-7x that stretches to 9x.
• Fixed 100-yard parallax rules out precision rimfire at mixed close distances.
• Capped, soft-clicking turrets and SFP holdovers (true only at 9x): not a dial-for-distance scope.
• No illumination: the fine crosshair can wash out in deep timber at last light.

Key specifications

Should you buy it, and what else to consider

• Buy it for budget deer and general hunting inside 300 yards, first scopes, and brush or lever guns.
• Spend up to the Leupold VX-Freedom for low-light glass and less weight, or jump to the Diamondback Tactical if you actually want to dial and shoot far.
• Skip it for precision rimfire and long-range dialing; see the Strike Eagle 5-25x56.
