Back Up Iron Sights: Your Guide to Keeping it Real

Back up iron sights (BUIS) are like a spare tire for your rifle. They are there when your main optic, like a scope or red dot, fails. They are simple, reliable, and ready to go. This guide will help you choose the right ones.

Key Features to Look For

Here are things to think about when picking BUIS:

  • Adjustability: Can you change the sights to hit your target? Good BUIS have adjustments for windage (side-to-side) and elevation (up and down). This helps you hit where you aim.
  • Sight Picture: Do the sights line up easily? You want a clear view of the front and rear sights. This helps you aim quickly.
  • Deployment: How fast can you use the sights? Some flip up quickly with a button. Others use springs. Choose a system that’s easy and fast to use.
  • Profile: How tall are the sights? Low-profile sights are better. They stay out of the way of your optic. They also reduce the chance of snagging on something.
  • Compatibility: Do the sights fit your rifle? Make sure they work with your rail system. Most rifles use a Picatinny rail. This is a standard rail.
  • Durability: Can the sights take a beating? Look for sights that are strong and can handle rough use.
Important Materials

The materials matter. They affect the strength and how long the sights last.

  • Aluminum: This is a common material. It is lightweight and strong. It is also resistant to corrosion.
  • Steel: Steel is very strong. It can handle a lot of abuse. Steel sights may be heavier than aluminum ones.
  • Polymer: Polymer is a type of plastic. It is lightweight and affordable. Polymer sights can be a good choice for some users. They might not be as durable as aluminum or steel.
Factors That Improve or Reduce Quality

Quality is important. Here’s how to tell if a sight is good:

  • Manufacturing: Look for sights made well. The parts should fit together tightly. The finish should be smooth.
  • Design: Simple designs are often better. Fewer parts mean fewer things that can break.
  • Finish: The finish protects the sights. It also helps with durability. Look for a good finish. It should resist scratches and rust.
  • Brand Reputation: Some brands make better products than others. Research the brand before you buy. Read reviews. See what other people say.
  • Price: You usually get what you pay for. Cheap sights may not be as good as more expensive ones.
  • Zero Retention: Good sights hold their zero. This means they stay accurate after you adjust them.
User Experience and Use Cases

BUIS are useful in many situations.

  • Primary optic failure: If your optic breaks, your BUIS are ready. You can switch to them quickly.
  • Close-quarters combat (CQB): BUIS can be faster than optics at close range. You can quickly acquire targets.
  • Training: BUIS are good for training. They teach you the basics of aiming.
  • Backup: Everyone needs a backup. BUIS are a backup for your main sighting system.

Here’s how to use them:

  1. Deploy the sights: Flip them up when you need them.
  2. Align the sights: Line up the front sight with the rear sight.
  3. Focus on the target: Put the sights on the target.
  4. Squeeze the trigger: Gently pull the trigger.
