Bushnell 3-9x40eg Manual ★ Validated

If you have lost the manual, here are the critical specs you are missing. Do not deviate from these when mounting or cleaning.

The 3-9x40EG typically features capped, finger-adjustable turrets (1/4 MOA per click). The manual provides the crucial "Set Screw" procedure:

This allows you to dial back to your exact zero even after field adjustments. Lose the manual, and you might strip that tiny set screw using the wrong tool (often a 1.5mm or 2mm hex key, as noted in the manual).

A scope is only as good as its mount.

The 3-9x40eg is typically a "parallax fixed" scope, set for 100 yards. This means at 9x power, if your eye moves behind the scope, the crosshairs might shift slightly. The manual instructs you to always center your eye behind the scope for maximum accuracy.

Overall Rating: 4.5/5
Best for: Beginner to intermediate hunters, .22 plinkers, and full-size rifle owners on a budget.

The Scope The Bushnell 3-9x40EG is a staple in the hunting community. It offers the universal magnification range (3-9x) for short to medium-range shots and a 40mm objective lens for excellent light gathering at dawn/dusk. The "EG" typically denotes the Multi-X crosshair reticle and exposed, finger-adjustable turrets.

Pros:

The Manual (Key Focus) Unlike many scopes that come with a confusing, one-sheet "quick start" guide, the Bushnell 3-9x40EG manual is a standout. It's a 12-16 page booklet (or PDF) that actually teaches you:

Cons:

Leveling: Use a small level to ensure the reticle’s vertical crosshair is perfectly aligned with the rifle's action to prevent "canting" errors at long distances. Zeroing the Scope

Bore Sighting: Start by aligning the scope with the barrel at 25 yards to ensure you are "on paper." Windage and Elevation: Use the capped adjustment turrets. 1 Click = 1/4 MOA (approximately 1/4 inch at 100 yards).

Rotate the Elevation turret (top) to move the impact up or down.

Rotate the Windage turret (side) to move the impact left or right.

Final Zero: Confirm your zero at 100 yards by firing a 3-shot group and making final micro-adjustments. Reticle Illumination

The EG model features a battery-powered rheostat (usually located on the eyepiece or a third turret).

Operation: Rotate the dial to select between Red or Green illumination.

Brightness: Numbers 1–5 indicate intensity; lower settings are ideal for dawn/dusk, while higher settings help in bright daylight. Battery: Typically uses a CR2032 3V lithium button cell. Maintenance and Care

Lens Cleaning: Use a soft microfiber cloth or a lens pen. Avoid using shirts or abrasive materials that can scratch the multi-coated glass.

Storage: Store in a cool, dry place with lens caps on to prevent dust accumulation.

Waterproofing: While often advertised as water-resistant, avoid submerging the unit and ensure the turret caps are tightly sealed.

Bushnell Trophy Rifle Scopes Instruction Manual - Optics Trade

The rain had been falling for three hours when Lena finally admitted it: she had no idea how to zero her late father’s Bushnell 3-9x40EG scope. The rifle—an old Remington 700—lay across the tailgate of her truck, and the scope’s crosshairs seemed to dance every time she touched the turrets.

“Come on, Dad,” she whispered, wiping fog off the eyepiece. She’d found the rifle in his closet a week after the funeral, wrapped in an oiled cloth. No box, no papers. Just the scope, a faint scratch on the objective bell, and a memory of him saying, “That Bushnell 3-9x40EG never lost zero, not once in twenty years.” If you have lost the manual, here are

But Lena was a historian, not a hunter. She’d spent her life in archives, not deer blinds. The “EG” on the scope body meant nothing to her—Enhanced something? Early Generation? She’d typed “bushnell 3-9x40eg manual” into her phone at least ten times, but the cellular signal in the Blue Ridge Mountains was a cruel joke.

Frustrated, she twisted the magnification ring. It clicked through 3x, 5x, 7x, landing at 9x. Through the lens, the target 100 yards away—a rusted coffee can she’d propped on a stump—looked close enough to touch. But the last three shots had missed entirely. Two hit dirt left. One kicked up pine needles six inches low.

She unscrewed the turret caps. Windage and elevation adjustments: crisp, tactile clicks. But which way? The manual wasn’t here. Her dad wasn’t here. All she had was a crumpled receipt from 1998 tucked in the stock’s buttplate: Bushnell 3-9x40EG, $129.99, Dick’s Sporting Goods.

Then she noticed something. On the underside of the scope, near the saddle, tiny letters engraved: 1 click = 1/4" at 100 yds. And below that, an arrow: UP = counterclockwise.

Her heart jumped. She turned the elevation turret left—counterclockwise—and felt a firm click. Then she dialed windage right two clicks. Breathed. Squeezed.

The coffee can jumped off the stump with a satisfying ping.

Lena laughed, the sound strange in the quiet woods. She didn’t need a PDF. She didn’t need a manual. Her father had left the instructions where they belonged—on the instrument itself, etched in steel, waiting for her to slow down and look.

She chambered another round, smiled, and whispered, “Thanks, Dad.” The Bushnell 3-9x40EG held its zero. Just like he said it would.

One of the most common user errors is failing to set the diopter correctly. The manual dedicates a critical Step 1 to this process, which many skip:

The manual warns: If you adjust the eyepiece while looking at a target, your eye will automatically compensate, causing eye strain and fuzzy images later.

If you want the exact official manual PDF, tell me whether you want a web search for the precise Bushnell model number (e.g., full model code on the scope) and I’ll look it up.
