As someone who owns an AR 15, I can confidently say that a rear sight is an essential component of this firearm. The AR 15 is a highly versatile and accurate rifle, and the rear sight plays a crucial role in achieving that precision.

Firstly, the rear sight allows me to adjust the elevation and windage of my shots. This means that I can fine-tune my aim to account for any environmental factors such as wind or distance. Without a rear sight, it would be nearly impossible to accurately hit my target at different ranges or in varying weather conditions.

Moreover, the rear sight provides a reference point for my eye to align with the front sight and target. This is especially important when using iron sights, as it allows for consistent and repeatable shots. Without a rear sight, I would have to rely solely on my instinct and judgment, which is not always reliable.

Additionally, the AR 15’s modular design allows for various types of rear sights to be mounted on the rifle. Whether it’s a traditional peep sight or a more advanced holographic sight, the versatility of the AR 15 ensures that there is a suitable option for every shooter’s preference.

In conclusion, an AR 15 without a rear sight would be like driving without mirrors –

My Buying Guide on ‘Ar 15 Rear Sight’

As an avid shooter and owner of an AR 15, I understand the importance of having a quality rear sight for accurate and reliable shooting. After extensive research and personal experience, I have compiled a buying guide for anyone looking to purchase an AR 15 rear sight. Here are the key factors to consider:

Durability and Quality

The first thing to look for in an AR 15 rear sight is its durability. This is crucial as it will be exposed to the recoil of the rifle, which can cause wear and tear over time. Look for rear sights made from high-quality materials such as aircraft-grade aluminum or steel. These materials are known for their strength and ability to withstand heavy use.

Additionally, pay attention to the build quality of the rear sight. It should feel solid and sturdy when attached to your rifle. Avoid purchasing cheaply made rear sights as they may not hold up well under constant use.

Type of Rear Sight

There are two main types of rear sights for AR 15 rifles – aperture (peep) sights and flip-up sights. Aperture sights are fixed and have a small hole or aperture through which you aim at your target. Flip-up sights, on the other hand, can be flipped up when needed but fold down when not in use.

The type of rear sight you choose depends on your shooting style and preferences. If you prefer a traditional sight picture, then aperture sights may be more suitable for you. However, if you want the option to switch between iron sights and optics quickly, then flip-up sights may be a better choice.

Sight Adjustment

Most AR 15 rear sights come with windage (left-right) and elevation (up-down) adjustment knobs or dials. These allow you to make small adjustments to your sight in order to zero in on your target accurately.

When looking at different rear sights, pay attention to how easy it is to adjust them. Some have large dials that can easily be turned with gloved hands, while others may require a tool for adjustments.

Budget

The price range for AR 15 rear sights can vary greatly depending on the brand, material used, and features offered. Before making a purchase, determine your budget and stick within that range.

Remember that while cheaper options may save you money upfront, they may not last as long or provide the same level of accuracy as more expensive options.

Compatibility

Last but not least, make sure that the rear sight you choose is compatible with your specific AR 15 model. Some rifles may require specific types of mounts or may not fit certain types of rear sights. It is always best to double-check before making a purchase.

In conclusion, choosing an AR 15 rear sight requires careful consideration of its durability, type, adjustment capabilities, budget, and compatibility with your rifle model. By keeping these factors in mind during your search for a new rear sight, you can ensure that you make a well-informed decision that will enhance your shooting experience.
