Bushnell AR Optics Rifle Scope, What are the Parts to It? – All You Need to Know

This article will cover all about Bushnell AR Optics.

So, let’s get started!

Bushnell AR Optics Rifle Scope, What are the Parts to It?

Your Bushnell AR Optics riflescopes are precision instruments constructed of the finest materials. You should read the instructions carefully before mounting your riflescopes. The following are different parts of the scope.

Eyepiece Focusing

This adjusts the focus so that you can see the crosshairs appear sharp to your eyes. No adjustments are needed if the reticle appears sharp. If the reticle does not appear sharp, then adjust as follows.

Fast Focus Eyepiece Design

A telescope eyepiece is used to view objects far away. You must be patient when you’re viewing an object because you’ll need time to adjust the eyepiece. After adjusting the eyepiece, turn it clockwise or counterclockwise until the image is clear.

Mounting

Mounting your scope correctly is important. You need to make sure that you use a high-quality mount.

• Your scope should be mounted as close to the ground as possible without touching the barrel or the receiver of your rifle.
• The scope should be adjusted by looking through the scope in your shooting position.
• You should adjust the scope either forward or backward until you find the furthest point forward that allows you to see the full field of view.

The rifle should be mounted far enough forward to prevent injury when the gun recoils. The scope must be rotated in the rings until the crosshairs are perpendicular to the bore and then tightened down as much as possible.

Bore Sighting

Bore sighting is a preliminary procedure before shooting. A bore sighter is recommended. Windage adjustments must be made by adjusting the mount base. Major elevation adjustments should be made by shimming the mount.

Elevation and Windage Adjustment

Your Bushnell AR Optic Scope features finger-adjustable elevation and windage adjustments, as well as an audible-click mechanism. To adjust elevation, grasp the top of the target turrets and turn them in the appropriate direction.

Models Target Turrets

1. You’ve removed the turret from the barrel. Now you must remove the front sight assembly.
2. Remove the front sight assembly by loosening the two Phillips head screws holding the front sight assembly into place.
3. Unscrew the rear sight assembly by turning the screw counter-clockwise.
4. Remove the rear sight assembly by pulling it out of the receiver.
5. Rotate the rear sight assembly until the notch aligns with the notch in the receiver.
6. Screw the rear sight assembly back into place.
7. Replace the front sight assembly by tightening the three hex screws.
8. Reinstall the rifle by reversing steps 1-7.
9. Realign the zero marks on top of the removable turret cap with index dots.
10. Tighten the three hex screws around perimeter of

You must realign the zero marking on your target turret with the index marks on your scope. Then seat the target turret cap.

Variable Power Adjustments

To change magnification, fold the throw-down PCL out and use it to turn the power selector ring so the desired number on power scale is aligned with index dot 3x in the photos.

For even more rapid power changes, unscrew the top part of the pcl and replace it with the shorter pcl included. Lower powers provide a wider view. Higher powers should only be used for precise long-range shooting. The drop zone BDC reticle is calibrated for high power settings on your scope.

Parallax Focus Control Select Models

Parallax error is eliminated by adjusting the side focus knob. You can also use this feature to adjust the magnification.

Drop Zone Rimfire Ballistic Reticle

Scopes with the DROP Zone 22 rim re Reticle are designed for shooting at long distances. They are calibrated for use with.22 Long Rifle high velocity ammunition.

To make sure the reticle works properly, you need to set your magnification to the highest setting. For the 2-7x32mm model, this means setting the power change ring to 7x.

A laser rangefinder is used to determine the distance to the target. Magnification is set to 7x.

Hold the gun straight out in front of you. Aim at the target at 115 yards.

Drop Zone Ballistic Reticle

• A scope with a drop zone reticle is designed to be used with 5.56 ammo loaded with 62 grains or larger bullets.
• The top of the bottom post represents a holdover point for a shot at 605 yards.
• The reticle is calibrated for 223 ammo loaded with 55 grains or smaller bullets.

All AR optics scopes must be turned to the highest magnification setting for the ballistic reticle to function properly. In this example, the 3-9x40mm model should be set at 9 power, while the 4.5-18 x 40mm model should be set to 18 power.

A laser rangefinder is an instrument used to measure distances. You use this tool by aiming it at your target and then looking into the eyepiece. This device allows you to determine the exact range of your target.

Aiming Points

Aiming points should be placed on the target at 350 yards. Hold your rifle scope directly between the 300-yard aiming point and the 400-yard aiming point.

A laser rangefinder is used by hunters to determine distances to targets. The reticle is set to 100 yards. The magnification is set to its highest power.

Aiming points should be placed on targets at distances of 100 yards or less. Targets further than this distance require more precise aiming techniques. A rifle scope must be adjusted properly before firing.

BTR Tactical Reticle

Scopes with the Bushnell BTR-1 reticles are designed to be sight-in at 100 yards, with aiming points every hundred yards, out to 500 yards. These scopes are calibrated for use with 223mm ammunition loaded with 55- 62 grain bullets.

Because these scopes are located in the first focal plane position within the scope, they will be accurate for all target distances at any magnification setting.

Drop Zone Creedmoor Reticle

This is an ideal riflescope for use with 6.8 Creedmoor cartridges. Bullet drop compensation is shown by the dots below the crosshair. The image on the right shows the Drop Zone 6.7 reticle.

BTR Blackout Reticle

The BTR-300 reticles can be used with both supersonic and subsonic velocity loads. It should be sighted-out at 50 yards when using subsonic loads. At 100 yards, you can use the two lower dots for 235 and 300 yards.

Conclusion

A brightness adjustment control is used to adjust the amount of light coming out of the scope. When you store the scope, you must remove the cap on the knob and put a new battery in.
