Doves, Dots & Realities: Hunting Doves with the Aimpoint Acro S-2

If you’ve ever lost a dove against a washed-out September sky or felt your bead go fuzzy just as a bird flared, you’ve probably wondered if there’s a better way to aim a shotgun than “hope and instinct.” Red dots aren’t the norm on bird guns, but for hunters with aging eyes or soft-focus issues, the right dot can clean up the sight picture without turning a wingshot into a rifle shot. The Aimpoint Acro S-2 is one of the few optics built specifically for shotgun ribs, and after a season of practice and field time, here’s a real-world look at what it does well, where it can get in your way, and how to use it effectively for birds or clays.

‍

What the Acro S-2 Is (and Isn’t)

The S-2 is a closed-emitter red dot designed to clamp directly to a ventilated shotgun rib, using included base plates that fit common rib widths. It runs a large 9-MOA dot, has ten daylight brightness settings, and is built on the second-generation ACRO architecture known for being sealed, durable, and simple. Aimpoint rates battery life at up to 50,000 hours on one CR2032 cell, and the sight body weighs about 2.4 oz.—light enough not to torpedo the lively feel of a field gun. Height over the rib is kept low (optical axis ~15 mm above the mount), and the optic is submersible to 15 ft—not that your dove field doubles as a duck slough, but durability is durability.

A big note for shotgun hunters: the enclosed emitter means dust, chaff, sweat, and weather are kept off the LED and rear lens—one reason the ACRO line is popular on hard-use pistols and carbines. That same design makes sense around cord-grass, milo stalks, and the general grit of opening day.

Aimpoint also leans into “operationally parallax-free” marketing language. In practice, it means you keep both eyes open, get the dot on what you want to hit, and press; small head-position errors don’t throw shots wildly off target. The sight turns on at a mid-high setting (7 of 10), with plus/minus buttons to adjust quickly when the sun ducks behind clouds or you spin into a shaded treeline.

‍

Why a Dot for birds?

Aging eyes and soft focus make a front bead and rib go from crisp to ghostly. With a red dot, your focal plane stays on the bird—the dot lives in the same visual layer. On high, hard crossers or birds that flash through gaps, that single point of reference can reduce the “bead-chasing” that leads to stopping your swing. A 9-MOA dot is intentionally big: at 30 yards it subtends roughly 2.7 inches—small against a dove’s arc but large enough to grab your attention without needle-point precision. Think of it as a glowing pseudo-bead that floats where the muzzle is headed.

That said, a red dot does not replace lead judgment or a smooth mount. If you try to “park” the dot on a dove and press like you’re shooting a static steel plate, you’ll miss behind all afternoon. The dot is a reference, not a brake.

‍

Mounting & Setup: Don’t Skip the Boring Stuff

The S-2 ships with an ultra-low mount that clamps to ventilated ribs and a set of interchangeable base plates. The plates matter. They’re sized for rib width and thickness; get the wrong combo and you’ll either pinch the rib or never truly clamp it. Aimpoint sells thin-rib and thick-rib plate sets; the manual includes a selection guide and cautions about how the locking plate should sit—flush is your friend. Take ten minutes to measure your rib and choose the plates that fit just right. Then use thread prep as specified, torque evenly, and re-check after your first box of shells.

Two more setup notes:

• Comb height: Even with the low mount, the window can sit higher than your bead. If you’re floating the stock and “fishing” for the dot, add a temporary cheek riser (tape-on foam or a slip-on pad) until your natural mount puts your eye dead behind the window. Your goal is to see the dot automatically when you mount, not hunt for it.
• Balance: 2.4 oz doesn’t ruin a lively 20-gauge, but you are adding mass forward of your hands. On long, hot days the barrel may feel slightly steadier on sustained leads and slightly slower to start on snap shots. That’s a trade some hunters like.

‍

Zeroing & Patterning: Set the Dot to Your Shot

Wingshooters don’t “zero” in the rifle sense—but you do want the center of your pattern to land where your mount puts the muzzle. Here’s a quick routine:

• Pattern board at 16–20 yards. Mount naturally and fire as the bead (or dot) settles on the target center. Don’t aim—mount and shoot. Do this five times with the dot at a comfortable brightness. You’re mapping your natural point of impact (POI).
• Evaluate the pattern center. If you shoot a 60/40 or 70/30 gun (common for field guns), decide whether you want to keep that. For doves, a 50/50 or mild 60/40 is a good all-around choice.
• Adjust the S-2. Windage/elevation clicks are audible/tactile; adjustments are made in MOA-type increments. Move the dot so that your natural mount puts the bulk of the pattern where you want it. Don’t adjust your mount to the optic—tune the optic to your mount.
• Confirm at 30–35 yards. Shoot three more natural-mount shots on a larger sheet. If the dot floats where your patterns center, you’re set.

This approach keeps the dot an honest indicator of where your gun shoots when you aren’t over-aiming—exactly what you want in the field.

Brightness, Astigmatism & Dot Behavior

The S-2’s ten daylight settings include higher maximums tuned for bright sky conditions—helpful on pale, blown-out days. Keep the dot just bright enough to be crisp. Overdriving brightness can make the dot “bloom,” which looks like a starburst or comma—especially if you have astigmatism. Lower the setting a notch or two until the dot is round and stable against the sky. The sight’s default power-on at setting 7 is a nice middle ground; bump up for noon sun, bump down near dusk.

How to Actually Shoot Doves with a Red Dot

The mechanics are familiar, but the dot changes what you look at and when you confirm lead.

‍

Both eyes open; eyes on the bird. The dot is peripheral confirmation. If you stare at the dot, you’ll stop the gun. Trust your mount, read the line of flight, and see the dot drift just off the beak as you continue the swing.

Lead methods still apply. Whether you’re a “swing-through,” “pull-away,” or “sustained lead” shooter, the dot simply makes the relative gap more visible. With sustained lead, let the dot live just in front of the bird’s path and keep the gun moving through the shot. With pull-away, touch the bird with the dot, accelerate a smidge, and press as the dot clears to daylight.

Break the “check-the-dot” habit early. Early adopters tend to mount, stop, verify dot on bird, then fire—behind every time. Practice feeling the dot’s position without freezing the muzzle.

Use the window edge as a coaching tool. If the dot keeps escaping the top of the window, you’re lifting your head. If it drifts low left on every mount, your stock might be a hair long or your mount inconsistent. The S-2 can quietly coach your gun fit and mount quality.

‍

Drills to Get Comfortable (Before Opening Day)

• Dry Mounts + Corner Trace (5 minutes, daily). In a safe space with an unloaded gun, pick a corner or doorframe. Mount and “trace” a smooth crosser, keeping the dot floating along the edge without bouncing. Do sets of 10 mounts per side. The goal is a dot that appears instantly and tracks smoothly.
• Skeet Stations 3–4–5, High House first. These present true crossers similar to passing doves. On each shot, focus on a clean mount and continuous swing—let the dot slide just ahead of the bird as you press. Don’t chase perfect scores; you’re training rhythm.
• Report Pairs, Low → High. Doves rarely come one at a time. After the first shot, immediately reacquire the second bird line with your eyes, not the dot. The dot won’t help if you don’t see the second dove early.
• Low-Contrast Targets. If you can, shoot a few clays against pale sky or a tan berm. Dial brightness until the dot stays clean without glare; memorize that setting for similar conditions.

Practice matters. Switching to a dot without reps is like changing from a 28-inch barrel to a 22-inch the morning of the hunt—possible, but ugly.

Field Pros & Cons

The Good

• Cleaner sight picture for aging eyes. If your front bead fuzzes at arm’s length, the dot is liberating. You keep hard focus on the dove, yet still “know” exactly where the muzzle is pointing.
• Enclosed reliability. Dust, sweat, and field grit don’t shut the sight down. If you’ve ever had an open-emitter dot collect debris, you’ll appreciate the ACRO’s sealed design.
• Battery life you can ignore. Five-plus years is more than a season or three; replace the CR2032 once a year when you swap out your smoke-detector batteries and forget it.
• True “rib” solution. The included base plates make the S-2 a real shotgun product rather than a “make a pistol sight work somehow” plan. Once clamped correctly, it stays put.

The Trade-Offs

• Window height & stock fit. If your comb is low, you may fight to find the dot until you adjust fit. A slip-on riser solves it, but that’s still tinkering.
• Weight and swing character. It’s light, but you’ll feel a touch more inertia out front. Most shooters adapt quickly; very fast, snap-shoot style hunters might notice the start/stop tempo change.
• Habits die hard. Early on, many hunters “aim” the dot at the bird and stop the gun. You must keep the swing alive and treat the dot like a bright bead, not a crosshair.
• Cost. Quality glass and a specialized mount aren’t cheap. If your eyes are still hawk-sharp, your money might be better spent on ammo and clays.
  

Practical Details You’ll Care About

• On/Off & Defaults: The S-2 powers on at setting 7/10; hold the minus button to power off. That default is bright enough for most daylight; bump to 8–10 for blazing noon skies.
• Brightness Strategy: Run the lowest setting that stays crisp to avoid starburst. Keep one spare CR2032 in your vest’s license pocket.
• Water & Weather: You won’t be swimming for dove, but rain happens. The S-2’s IP-like submersion rating to 5 m is overkill—in a good way.
• Adjustment & Zero: Clicks are tactile/audible; if you’re nudging POI a few inches at 30 yards, take your time and map what a couple clicks do on paper before guessing. (Aimpoint’s literature pegs click value and adjustment ranges; use those as a baseline, then confirm on your gun.)
• Rib Plates: If your rib is unusually thin or thick, Aimpoint sells additional plate sets. Use the manual’s selection guide and install so the locking plate sits flush—not recessed or protruding wildly.

So…Should You Hunt Doves with the S-2?

If you’re a traditionalist with laser eyes and a perfect mount, a bead still kills birds just fine. But for a lot of hunters—especially those noticing the bead fuzz or having trouble keeping hard focus on fast birds—the S-2 tidies the picture without demanding new mechanics. It keeps the field of view open, confirms lead visually, and doesn’t melt down if a dust devil sweeps your stand.

It isn’t magic. You will need a couple boxes of clays to rewire your brain not to over-aim. You may need a cheek-piece tweak. And you might notice slightly different swing timing. But with a few evenings of practice, most shooters find their hit percentage on straight pass-shooters and medium crossers goes up, and—maybe more important—their confidence does too.

If that sounds like you, set up the mount correctly, pattern to your natural POI, practice until the dot appears without thought, and go enjoy one of the most social, forgiving hunts of the year with a sight picture that works with your eyes, not against them.
