Operation Of The Self Locking Lever

The self locking lever is designed to be operated with one hand.

Operation Of The Self Locking Lever

The user simply presses the release button and slides the sight forward or backward on the rail until it is in the desired position. To lock the sight in place, the user pushes down on the lever until it locks into place.

Adjustment Of The Self Locking Lever

To adjust the self locking lever, first loosen the two screws that hold it in place. Then, simply rotate the lever to the desired position and retighten the screws. That’s all there is to it!

Changing The Position Of The Self Locking Lever

The self locking lever is what you use to make sure the sight does not move when you are trying to take a shot. If you need to change the position of the self locking lever, here is how you do it.

First, loosen the two screws that hold the base in place. Then, slide the base forward or backward until it is in the desired position. Finally, retighten the screws and check that the sight is secure before taking your shot.

Keep in mind that changing the position of the self locking lever will also change the point of impact. So if you are having trouble hitting your target, this is one thing you can adjust to try and improve your accuracy.

Focus adjustment

To adjust the focus on the M332, you need to look through the sight and rotate the eyepiece until the crosshair is in focus. Once you have the crosshair in focus, you can fine-tune the focus by turning the knob on top of the sight.

Battery replacement

To replace the battery, first remove the protective cover from the back of the sight. Next, unscrew the battery compartment cover and insert a new CR2032 battery with the positive side (the side with the + symbol) facing up. Finally, screw the cover back on and replace the protective cover.

Care & Maintenance

It is important to keep your prism sight clean and free of debris to ensure optimal performance. Use a lens cloth or soft brush to gently remove any dirt or fingerprints. Avoid using harsh chemicals or solvents as they can damage the lenses.

To maintain the waterproof seal on your prism sight, it is recommended that you use a silicone-based lubricant on the O-rings.
This will help to prevent them from drying out and cracking. Inspect the O-rings regularly for any damage and replace them if necessary.

Care & Maintenance

Store your prism sight in a cool, dry place away from direct sunlight when not in use. This will help to prolong its lifespan.

Tips And Considerations

  • During zeroing, be sure to use the knob on top of the sight for windage and elevation adjustments.
  • For long range shots, make use of the Bullet Drop Compensation (BDC) feature.
  • Don’t over tighten the screws when mounting it to your weapon as this might damage the threads.
  • Don’t forget to clean and lubricate the O-rings regularly to maintain the waterproof seal.


Will this work with Acog mounts?

The Steiner M332 Prism Sight will not work with Acog mounts.

What reticle is best?

The M332 comes with a choice of four different reticles: Circle Dot, Crosshair Dot, Crosshair, and Mil-Dot. All are fine options, but which one you choose will depend on your personal preference and intended use for the sight. If you plan on using the sight for close-range shots, the Circle Dot or Crosshair Dot reticle might be a good choice. For longer-range shots, the Crosshair or Mil-Dot reticle might be a better option.

What power scope do you need to shoot 1000 yards?

In order to shoot at 1000 yards, you will need a scope with at least 32x magnification. However, it is important to note that the size of your target will also affect how much power you need. If you are shooting at a small target, you may need a higher powered scope.

What does a fully multi-coated lens mean?

Fully multi-coated lenses provide the highest level of light transmission, meaning that you’ll have a bright and clear image even in low-light conditions. With such a lens, every surface – both internal and external – has multiple coatings of anti-reflective material. This ensures that the maximum amount of light reaches your eye, resulting in a brighter image.

How can you tell if a lens is multi coated?

If you look at the lens from the side, you will be able to see light reflecting off of it at different angles. This is because each layer of coating reflects light in a different way. By looking at the reflections, you can tell how many layers of coating are on the lens. Multi-coated lenses will have more reflections than single-coated lenses.

How can you tell if a lens is multi coated?

Another way to tell if a lens is multi coated is to look at the color of the reflections. Multi-coated lenses will have colors that are very close to each other, while single-coated lenses will have colors that are more distinct from each other.

How do you clean multi coated glasses?

Use a soft, clean cloth to wipe any smudges or fingerprints from the lenses. For more stubborn dirt and grime, you can use lens cleaning solution and a microfiber cloth. Be careful not to scratch the lenses when cleaning them.

It is important to keep your Steiner M332 Prism Sight clean so that you can continue to enjoy using it for many years to come. With proper care, it will serve you well for a long time.

How long do lens coatings last?

Lens coatings are designed to last the lifetime of the lens. However, they can be damaged by harsh cleaning chemicals, UV light, and scratches. It is important to clean your lenses carefully and to avoid exposing them to damaging elements.

How do I know if my lens coatings are still effective?

You can test the effectiveness of your lens coatings by holding a sheet of white paper up to the sun and looking through your lenses at the paper. If the lens coatings are still effective, you should see a blue or green tint on the paper. If the coatings are damaged, you will see a brown or yellow tint.

What are the best lens coatings for my needs?

The best lens coatings for you will depend on your specific needs. If you need maximum protection from UV light and scratches, you should choose a coating that includes both of these features. If you only need one or the other, you can choose a coating that only includes one of these features.

Are there any special care instructions for lens coatings?

Yes, there are special care instructions for lens coatings. You should avoid cleaning your lenses with harsh chemicals or exposing them to UV light or scratches. Instead, clean your lenses carefully with a soft cloth and store them in a safe place when not in use.

I’ve heard that some lens coatings can actually damage my lenses. Is this true?

Some lens coatings can damage your lenses if they are not applied correctly or if they are not compatible with your lenses. Always consult a professional before applying any type of coating to your lenses.
