As an experienced gun enthusiast and owner of multiple AR rifles, I can confidently say that an upper receiver block is an essential tool for any AR owner. This simple yet effective device allows for safe and secure maintenance and customization of the upper receiver, making it a must-have for any serious gun owner.

One of the main reasons why I believe an AR upper receiver block is necessary is because it provides a stable platform for working on the upper receiver. The block securely holds the upper receiver in place, preventing it from moving or falling while you are working on it. This makes tasks such as cleaning, installing new parts, or even just changing optics much easier and safer.

Another reason why I highly recommend investing in an AR upper receiver block is its versatility. Most blocks are designed to accommodate different types of AR uppers, making them suitable for use with various models and calibers. This means that you can use the same block for all your AR rifles, saving you money and space in your gun cleaning kit.

Lastly, an upper receiver block also helps prevent damage to your rifle during maintenance. By keeping the upper receiver securely in place, there is less risk of accidentally scratching or dropping your rifle while

My Buying Guide on Ar Upper Receiver Block

As a gun enthusiast, I have always been fascinated by AR rifles. And as a DIY enthusiast, I wanted to build my own AR rifle from scratch. But one of the most challenging parts of building an AR rifle is installing the upper receiver. This is where an AR upper receiver block comes in handy. It not only makes installing the upper receiver easier but also protects it from any damage during the installation process.

What is an AR Upper Receiver Block?

An AR upper receiver block is a specialized tool that securely holds the upper receiver of an AR rifle in place. It usually has a slot or groove that fits perfectly with the shape of an AR-15 upper receiver, providing a stable and tight grip. This ensures that the upper receiver remains in place while you work on it, without causing any damage to its delicate parts.

Why do you need an AR Upper Receiver Block?

If you are planning to build or customize your own AR rifle, investing in an upper receiver block is essential for several reasons:

  • It provides a stable base for working on your upper receiver
  • It protects your upper receiver from scratches or dents during installation
  • It helps in aligning and positioning your upper receiver accurately
  • It allows for easy access to all parts of the upper receiver for cleaning or maintenance

Factors to consider before buying an AR Upper Receiver Block

When it comes to choosing the right AR upper receiver block, there are a few factors that you should keep in mind:

  • Type: There are two types of AR upper receiver blocks – vise-mounted and bench-mounted. Vise-mounted blocks clamp onto your vise, while bench-mounted blocks require drilling holes into your workbench. Consider which type would be more suitable for your needs.
  • Material: The most commonly used materials for these blocks are polymer and aluminum. Polymer blocks are lightweight and affordable, while aluminum blocks are more durable and sturdy.
  • Budget: Set a budget based on how often you plan on using the block and what features you require.
  • Grip Strength: Look for blocks with rubber padding or grooves to ensure a strong grip on your upper receiver without causing any damage.

My Recommended Products

I have personally used and tested these two products before building my own AR rifle:

  1. Aero Precision Ultralight Scope Mount:
    This bench-mounted block is made from high-quality aluminum and has rubber padding to hold onto your upper receiver securely. It also has pre-drilled holes for easy mounting onto your workbench. It’s lightweight yet sturdy design makes it perfect for frequent use.


  1. Magpul BEV Block – Enhanced Version:
    This versatile vise-mounted block can be used with both standard and billet uppers. Its polymer construction makes it lightweight yet durable, with excellent grip strength due to its rubberized pads. It also has built-in features like barrel extensions alignment pin and gas tube alignment pin which come in handy when assembling or disassembling an AR-15.
