Installation
1. Montage de la lunette de visée
The Bushnell Prime Riflescope is designed for use with a Picatinny Mount. Ensure the mount is securely attached to your rifle's receiver.
- Positionnement : Place the riflescope on the mount, ensuring proper eye relief. Eye relief is the distance between your eye and the eyepiece lens when you have a full field of view. This is crucial for safety and comfort.
- Ring Placement: Secure the scope rings around the riflescope tube. Do not overtighten initially.
- Mise à niveau : Use a leveling tool to ensure the reticle is perfectly horizontal.
- Contraction: Gradually tighten the scope ring screws in an alternating pattern to ensure even pressure. Refer to your mount manufacturer's specifications for torque settings.

2. Focusing the Eyepiece (Diopter Adjustment)
The eyepiece allows you to adjust the focus of the reticle to your individual eye.
- Point the scope at a clear, bright area (like a plain wall or the sky).
- Regardez dans la lunette et jetez un coup d'œil rapide au réticule.
- Rotate the eyepiece (the ring closest to your eye) until the reticle appears sharp and clear. Avoid staring at the reticle for too long, as your eye may compensate for blurriness.
- Once focused, the reticle should remain sharp regardless of magnification changes.
3. Réglage du grossissement
The magnification ring is located forward of the eyepiece. Rotate this ring to adjust the magnification from 3x to 12x.

Utilisation de la lunette de visée
1. Windage and Elevation Adjustments (BDC Turrets)
Your riflescope features Ballistic Drop Compensating (BDC) turrets for precise adjustments. The elevation turret is on top, and the windage turret is on the right side of the scope. Each click of the turret moves the point of impact by a specific amount (e.g., 1/4 MOA).
- Tourelle d'élévation : Permet de régler le point d'impact vertical. Tournez dans le sens horaire pour abaisser le point d'impact, dans le sens antihoraire pour le relever.
- Tourelle de dérive : Permet de régler le point d'impact horizontal. Tournez dans le sens horaire pour déplacer le point d'impact vers la droite, dans le sens antihoraire pour le déplacer vers la gauche.
Remise à zéro: To zero your rifle, fire a group of shots at a target. Observe where the shots impact relative to your aim point. Adjust the turrets to move the point of impact towards the center of the target. Repeat until satisfied.
2. Reticle Type: Multi-X
The Bushnell Prime Riflescope utilizes a Multi-X reticle. This is a classic duplex-style reticle, known for its clean sight picture and ease of use in various lighting conditions. It features a fine crosshair in the center for precise aiming, transitioning to thicker posts towards the edges for quick target acquisition.

Entretien
1. Nettoyage des lentilles
To maintain optical clarity, keep the lenses clean.
- Use the provided lens cloth or a soft, lint-free cloth.
- Gently brush away any loose dust or debris.
- For stubborn smudges or fingerprints, use a small amount of lens cleaning fluid specifically designed for optics. Apply to the cloth, not directly to the lens.
- Évitez d'utiliser des produits chimiques agressifs, des chiffons abrasifs ou une pression excessive, car ceux-ci peuvent endommager le revêtement des lentilles.
2. Entretien et stockage généraux
- Keep the lens covers on when the riflescope is not in use to protect the lenses from dust and scratches.
- Rangez la lunette de visée dans un endroit frais et sec, à l'abri de la lumière directe du soleil et des températures extrêmes.
- Évitez de faire tomber la lunette de visée ou de la soumettre à des chocs violents.
- Vérifiez régulièrement le serrage de toutes les vis de fixation.
Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| Réticule flou | L'oculaire n'est pas correctement mis au point. | Adjust the diopter (eyepiece focus) as described in the "Focusing the Eyepiece" section. |
| Inaccurate Shots / Poor Zero Retention | Loose mounting rings or base; damaged scope; inconsistent shooting technique. | Check all mounting screws for tightness. Ensure proper torque. If problem persists, inspect scope for damage or consult a gunsmith. |
| Formation de buée à l'intérieur des lentilles | Variations de température extrêmes ; étanchéité compromise. | Allow scope to acclimate to ambient temperature. If fogging persists internally, contact Bushnell customer service as the seal may be compromised. |
| Difficulty Adjusting Turrets | Turrets are locked; debris in mechanism. | Ensure turrets are unlocked (if applicable, some BDC turrets have a locking mechanism). Gently clean around the turrets. Do not force adjustments. |
