My Buying Guides on No Go Gauge 5.56
When I decided to invest in a No Go Gauge for my 5.56 caliber firearms, I wanted to ensure that I was making an informed choice. A No Go Gauge is a crucial tool for checking the headspace of my rifle chamber, and using one properly can mean the difference between a safe shooting experience and a potential mishap. Here’s my comprehensive guide to help you find the perfect No Go Gauge for your needs.
Understanding the Purpose of a No Go Gauge
Before I made my purchase, I took the time to understand what a No Go Gauge actually does. Essentially, it is used to check the maximum allowable headspace in a firearm chamber. If the bolt closes on the gauge, it indicates that the chamber may be too long, which can lead to dangerous situations like misfires or excessive pressure. This is why I consider it an essential tool for anyone serious about firearm safety.
Types of No Go Gauges
In my research, I found that there are different types of No Go Gauges available. Here are the main ones I came across:
- Standard No Go Gauge: This is the most common type and is typically used for general headspace checks. It’s what I opted for since it meets the basic needs of most shooters.
- Go/No Go Sets: These sets include both a Go Gauge and a No Go Gauge. I found this option appealing because it allows me to check both headspace limits, providing a more comprehensive assessment.
- Custom Gauges: If you have specific requirements or custom chambers, investing in a custom No Go Gauge can be beneficial. However, I decided this was not necessary for my standard 5.56 rifles.
Material and Build Quality
When I was shopping for my No Go Gauge, I paid close attention to the material and build quality. I found that most gauges are made from high-quality steel, which ensures durability. I preferred a gauge that is heat-treated or hardened to withstand regular use without warping or wearing out. My choice was a gauge that had a reputation for precision and longevity.
Accuracy and Calibration
Accuracy is paramount when it comes to headspace gauges. I learned that some brands are known for their consistent manufacturing processes, which yield more reliable measurements. I chose a gauge from a reputable manufacturer that provided calibration certificates, ensuring that I was getting a reliable product.
Price Range
I noticed that No Go Gauges come in a variety of price ranges. While I could find budget options, I opted for a mid-range gauge that offered both quality and affordability. In my experience, investing a little more can often lead to better performance and longevity.
User Reviews and Recommendations
Before finalizing my purchase, I read through several user reviews and recommendations. I found that hearing from other users about their experiences helped me gauge the reliability of the product. I looked for gauges with positive feedback regarding ease of use, accuracy, and durability.
Where to Buy
I found that No Go Gauges are widely available both online and in brick-and-mortar stores. I preferred shopping online for the convenience and access to a wider variety of options. However, I also visited a local gun shop to get a feel for the product before purchasing.
Conclusion
Ultimately, my experience purchasing a No Go Gauge for my 5.56 caliber firearms was straightforward and informative. By understanding the purpose, types, and quality of gauges available, I was able to make a well-informed decision.
