Why AR15 Grip Screw Size is Necessary

I have been an avid shooter for many years and have owned multiple AR15 rifles. One important aspect of maintaining an AR15 is ensuring that all its components are properly secured. This is where the grip screw size comes into play.

The grip screw is responsible for attaching the pistol grip to the lower receiver of the AR15. It may seem like a small and insignificant part, but it plays a crucial role in the overall stability and functionality of the rifle. A loose or improperly sized grip screw can lead to malfunctions, accuracy issues, and even safety concerns.

Having the correct grip screw size ensures a snug fit between the pistol grip and lower receiver, preventing any movement or shifting during use. This translates to more consistent shots and better control of the rifle. It also helps to distribute recoil evenly, reducing fatigue on the shooter’s hand.

Moreover, using the right size of grip screw prevents over-tightening or stripping of threads on either the pistol grip or lower receiver. These issues can be costly to fix and may render your rifle unusable until repairs are made.

In conclusion, proper sizing of an AR15 grip screw is essential for optimal performance, safety, and longevity of your rifle. As a

My Buying Guide on ‘Ar15 Grip Screw Size’

As a gun enthusiast and owner of an Ar15 rifle, I know the importance of having the right grip screw size for optimal performance. The grip screw is responsible for connecting the grip to the lower receiver of the rifle, making it essential to choose the correct size for a secure and comfortable hold. In this buying guide, I will share my knowledge and experience in selecting the right Ar15 grip screw size.

Understanding Ar15 Grip Screw Sizes

Before diving into the specifics of choosing an Ar15 grip screw size, it is crucial to understand how they are measured. Grip screws are typically measured in both length and thread pitch. The length refers to the distance from the head of the screw to its tip, while thread pitch indicates how many threads are present per inch of screw length.

Factors to Consider

When selecting an Ar15 grip screw size, there are a few factors that you should keep in mind:

1. Material: The most common materials used for grip screws are steel and aluminum. Steel screws tend to be more durable but heavier, while aluminum screws are lighter but less robust.

2. Thread Pitch: As mentioned earlier, thread pitch indicates how many threads are present per inch of screw length. The most common thread pitches for Ar15 grip screws are 28 TPI (threads per inch) and 20 TPI.

3. Compatibility: It is essential to ensure that your chosen grip screw is compatible with your specific model of Ar15 rifle. Some rifles may require a specific thread pitch or length.

Choosing the Right Size

Based on my experience, here are some general guidelines for choosing the right size for your Ar15 grip screw:

1. Determine thread pitch: Check your rifle’s manual or consult a gunsmith to determine the appropriate thread pitch for your particular model.

2. Measure length: Use a ruler or caliper to measure the distance from the head of your current grip screw to its tip.

3. Consider material: If you prefer a lighter rifle, opt for an aluminum grip screw with a similar or slightly longer length than your current one.

4. Check compatibility: Ensure that your chosen grip screw is compatible with your rifle’s make and model before purchasing it.

Tips for Installation

Once you have purchased and received your new Ar15 grip screws, here are some tips for installing them correctly:

1. Use proper tools: Use a proper-sized Allen wrench or torque driver when installing new grips screws to avoid stripping them.

2. Apply Loctite: To ensure a tight fit and prevent loosening over time, apply Loctite (a thread-locking compound) on the threads before installation.

In Conclusion

Choosing the right Ar15 grip screw size may seem like a small detail, but it can significantly impact your shooting experience. By considering factors such as material, thread pitch, compatibility, and proper installation techniques, you can find an ideal fit for your rifle’s specific needs. With this buying guide as a reference, I am confident that you will be able to make an informed decision when purchasing new Ar15 grip screws.
