As a gun enthusiast and AR15 owner, I have come to understand the importance of properly fitting components for optimal performance. One often overlooked component is the grip screw size on an AR15. While it may seem like a minor detail, the correct grip screw size is crucial for comfort, stability, and safety.

Firstly, the grip screw acts as an anchor for the pistol grip on the lower receiver. A loose or incorrect size screw can cause the grip to shift and affect the shooter’s ability to control and aim the gun. This can be particularly dangerous in high-stress situations where split-second accuracy is crucial.

Furthermore, using an incorrect size screw can also lead to discomfort and hand fatigue during extended shooting sessions. The wrong size may cause the grip to feel too loose or too tight, leading to discomfort and a potentially less accurate shot. This can greatly impact a shooter’s overall experience with their AR15.

Additionally, having the right grip screw size ensures compatibility with other aftermarket accessories such as trigger guards or handguards. Using an incorrect size may prevent these components from fitting properly or cause them to loosen over time.

In my experience, investing in a quality AR15 grip screw of the correct size not only improves comfort and stability but also ensures safety and compatibility with other parts.

My Buying Guide on ‘Ar15 Grip Screw Size’

As an avid firearms enthusiast, I have spent countless hours researching and upgrading my AR15. One of the most common upgrades for this versatile rifle is changing out the grip. However, with so many options available, it can be overwhelming to determine the correct grip screw size for your AR15. After much trial and error, I have compiled a buying guide to help others avoid the same mistakes I made.

Understanding Grip Screw Size

The first step in choosing the right grip screw size is understanding how they are measured. The standard measurement for grip screws is 1/4″-28 x 3/4″. This means that the screw has a diameter of 1/4 inch and a thread count of 28 per inch, with a length of 3/4 inch. However, there are variations in length and thread count that can affect compatibility with your AR15.

Compatibility with Your AR15

Before purchasing a new grip screw, it is important to check if it is compatible with your specific AR15 model. Some manufacturers may use non-standard sizes or have proprietary screws for their rifles. It is always recommended to consult your rifle’s owner’s manual or contact the manufacturer directly to ensure compatibility.

Types of Grip Screws

There are two main types of grip screws: standard and extended. Standard grip screws have a length of 3/4 inch and are flush with the bottom of the grip. On the other hand, extended grip screws have a longer length, typically ranging from 1-1/2 inches to 2 inches. These screws are designed for use with thicker grips or those that require more torque for installation.

Choosing the Right Length

When selecting a new grip screw, make sure to consider both the length of your current screw and the thickness of your chosen grip. If you are replacing your standard AR15 grip with another standard size, you can simply measure your current screw to determine its length. However, if you are upgrading to an extended or thicker grip, you will need to account for this added thickness when choosing a longer screw.

Thread Count Matters

As mentioned earlier, standard AR15 grip screws have a thread count of 28 per inch. However, some aftermarket grips may require different thread counts such as 32 or even 36 per inch. It is crucial to match the thread count of your new grip screw to that of your chosen grip for proper fitment and function.

The Importance of Quality

When it comes to firearms and their components, quality should always be a top priority. Cheap or low-quality grip screws can strip easily or break under pressure, leading to potential malfunctions or damage to your rifle. Invest in high-quality stainless steel or titanium screws from reputable manufacturers for added durability and peace of mind.

Consider Upgrading Your Hardware

While replacing just one part may seem like an easy task, it can often lead to noticing other parts that could use an upgrade as well. This is especially true when swapping out grips on an AR15 as it requires removing multiple components including trigger guards and safety selectors which may also be in need of replacement.

In conclusion,‘s buying guide on ‘Ar15 Grip Screw Size’ outlines everything you need to know before making this seemingly simple purchase. Consider compatibility with your specific rifle model, choose between standard and extended lengths based on your chosen grip thickness, pay attention to thread counts for proper fitment, invest in quality materials for durability and consider upgrading other hardware while you’re at it. By following these tips,‘s buying guide will help ensure you choose the perfect sized screw for upgrading your AR15’s grip.
