As a gun owner and enthusiast, I have owned and built numerous AR-15 rifles over the years. One of the most important components of an AR-15 is the grip screw, which is often overlooked but plays a crucial role in the functionality and comfort of the rifle.

First and foremost, the AR-15 grip screw is necessary for securing the grip to the lower receiver. Without a proper size screw, the grip may become loose or even fall off during use, compromising the stability and accuracy of the rifle. This can be especially dangerous in high-stress situations or during shooting competitions.

Moreover, using the correct size grip screw ensures that there is no extra play or movement between the grip and lower receiver. This not only improves accuracy but also allows for a more comfortable shooting experience. A loose or wobbly grip can cause discomfort and even pain in the shooter’s hand, leading to decreased performance.

Additionally, different sized grip screws may affect ergonomics and customization options for an AR-15. Most grips are designed to fit specific sizes of screws, so using an incorrect size could limit your choices when it comes to finding a comfortable and functional grip for your rifle.

Lastly, having a standard size for AR-15 grip screws makes it easier for gun owners to find

My Buying Guide on ‘Ar 15 Grip Screw Size’

As an experienced gun enthusiast, I have come across various challenges while purchasing parts for my AR 15 rifle. One of the most crucial parts that often gets overlooked is the grip screw size. The correct size of the grip screw is essential to ensure a secure and comfortable grip on your AR 15. In this buying guide, I will share my knowledge and experience to help you make an informed decision when it comes to selecting the right AR 15 grip screw size.

Importance of Choosing the Right Grip Screw Size

Before delving into the details of choosing the right grip screw size, it is essential to understand its importance. The grip screw plays a vital role in keeping your AR 15’s grip in place. It prevents any movement or wobbling that can affect your shooting accuracy and overall performance. Moreover, using an incorrect size can damage the threads in your rifle’s lower receiver, resulting in costly repairs.

Determining the Correct Size

The first step in choosing the right grip screw size is to determine the thread pitch of your rifle’s lower receiver. The most common thread pitches for AR 15 rifles are ¼ -28 and 1/4 -20. You can find this information by checking your rifle’s owner’s manual or consulting a gunsmith.

Types of Grip Screws

There are mainly two types of grip screws available for AR 15 rifles: standard and oversize. Standard grip screws are designed to fit perfectly with standard-sized grips, whereas oversize screws are slightly larger and allow for a more comfortable grip on larger hands.

Factors to Consider

When selecting a new grip screw for your AR 15, there are a few factors that you should keep in mind:

1. Material: The most common materials used for making grip screws are steel, aluminum, and titanium. Steel is durable but heavy, while aluminum is lightweight but not as strong as steel. Titanium offers both durability and lightweight properties but comes at a higher cost.

2. Knurled vs Smooth: Knurled screws have ridges around them that provide extra grip when tightening or loosening them. On the other hand, smooth screws have no ridges and require either a tool or careful handling to tighten or loosen them.

3. Coating: Grip screws come in different coatings such as black oxide, phosphate finish, or stainless steel finish. These coatings not only enhance the aesthetics but also provide resistance against corrosion.

Final Thoughts

Selecting the correct AR 15 grip screw size may seem like a minor detail but can make a significant impact on your shooting experience. Always ensure that you have determined the correct thread pitch before purchasing a new grip screw and consider factors such as material, type, and coating before making a decision.

I hope this buying guide has provided you with valuable information that will help you make an informed decision when it comes to choosing an AR 15 grip screw size for your rifle.
