3. Setup and Mounting
3.1 Mounting the Riflescope
Proper mounting is crucial for accuracy and consistent performance. Use high-quality scope rings and bases compatible with your rifle. Follow the manufacturer's instructions for your specific mounting hardware.
- Secure the bases to your rifle's receiver according to the base manufacturer's instructions.
- Place the lower halves of the scope rings onto the bases.
- Position the riflescope in the lower rings. Ensure adequate eye relief by holding the rifle in your normal shooting position and adjusting the scope forward or backward until you have a full, clear field of view without any black crescent (vignetting) around the edges.
- Rotate the scope until the vertical crosshair of the reticle is perfectly plumb (vertical) and the horizontal crosshair is level.
- Attach the upper halves of the scope rings and tighten the screws evenly, alternating between screws, until secure. Do not overtighten.

3.2 Focusing the Eyepiece (QTA)
The QTA eyepiece allows for quick and precise focusing of the reticle to your eye.
- Point the riflescope at a clear, bright area (like a blank wall or the sky), but not directly at the sun.
- Look through the scope and quickly glance at the reticle. If the reticle appears blurry, turn the eyepiece focus ring (located at the rear of the scope) clockwise or counter-clockwise until the reticle is sharp and clear.
- Avoid staring at the reticle for too long, as your eye may compensate for blurriness. A quick glance provides the most accurate focus.
4. Operating the Riflescope
4.1 Magnification Adjustment
The Simmons 8-Point 3-9x50 riflescope offers variable magnification from 3x to 9x. To adjust the magnification, rotate the power ring (located in front of the eyepiece) to your desired setting. The numbers on the ring indicate the magnification level.
4.2 Windage and Elevation Adjustments (TrueZero)
The riflescope features .25-MOA SureGrip audible-click windage and elevation adjustments. These turrets are designed to provide precise, repeatable adjustments and hold their zero.
- Elevation Turret: Located on top of the scope. Turning it clockwise moves the point of impact down; counter-clockwise moves it up.
- Windage Turret: Located on the right side of the scope. Turning it clockwise moves the point of impact right; counter-clockwise moves it left.
- Each audible click represents a .25 Minute of Angle (MOA) adjustment, meaning at 100 yards, each click will shift the point of impact by approximately 1/4 inch.
4.3 Reticle: TruPlex
The Simmons 8-Point 3-9x50 riflescope utilizes a TruPlex reticle, which is a common and versatile crosshair design. It is a Second Focal Plane (SFP) reticle, meaning its size appears constant regardless of the magnification setting. This simplifies aiming as the subtensions (the apparent size of the crosshairs) remain consistent relative to the target at a specific magnification (usually the highest setting).

5. Care and Maintenance
5.1 Cleaning the Lenses
To clean the lenses, first gently brush away any dust or loose debris with a soft lens brush or blow it off with compressed air. Then, use a clean microfiber lens cloth and a small amount of lens cleaning solution specifically designed for optics. Wipe the lenses gently in a circular motion. Avoid using harsh chemicals or abrasive materials, as these can damage the lens coatings.
5.2 Cleaning the Scope Body
Wipe the exterior of the riflescope with a soft, damp cloth to remove dirt or smudges. For stubborn grime, a mild soap solution can be used, followed by wiping with a clean, damp cloth and then drying thoroughly. Avoid getting moisture into the adjustment turrets or eyepiece.
5.3 Storage
Store your riflescope in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, consider using a protective scope cover to prevent dust accumulation and accidental scratches.
6. Troubleshooting
If you encounter issues with your riflescope, consider the following common solutions:
- Blurry Image/Reticle: Re-adjust the eyepiece focus (QTA) as described in Section 3.2. Ensure the objective lens is clean.
- Inconsistent Point of Impact: Check that the scope rings and bases are securely tightened. Ensure the barrel and action are free from obstructions or damage. Verify ammunition consistency.
- Fogging: While the scope is fogproof, external condensation can occur in extreme temperature changes. Allow the scope to acclimate to the ambient temperature or wipe external surfaces with a dry cloth.
- Difficulty Zeroing: Ensure proper mounting. If adjustments are not having the expected effect, check for loose components or contact customer support.
For persistent issues, contact Simmons customer support for further assistance.
