Why No Go Gauge 5.56 Is Necessary
From my experience, having a No Go gauge for 5.56 is absolutely essential when maintaining or building rifles. This gauge helps me ensure that the chamber dimensions of my firearm are within safe and reliable tolerances. Without it, I risk having a chamber that’s too tight or incorrectly sized, which can cause dangerous pressure issues or feeding problems.
I’ve found that using the No Go gauge gives me confidence that my rifle will function properly under normal conditions. If the No Go gauge fits into the chamber, it indicates that the chamber is oversized or out of spec, which can lead to case stretching or even catastrophic failures. By checking with this tool, I can catch problems early and avoid costly or hazardous malfunctions.
Ultimately, the No Go gauge is a small investment that provides peace of mind. It’s a critical part of the quality control process that every serious shooter or gunsmith should use to keep their 5.56 rifle safe and reliable.
My Buying Guides on ‘No Go Gauge 5.56’
When I first started looking for a No Go Gauge 5.56, I quickly realized how important it is to choose the right one to ensure safety and reliability in my firearms maintenance routine. Here’s what I learned and what I consider essential when buying this tool.
Understanding What a No Go Gauge 5.56 Is
A No Go Gauge for 5.56 is a precision tool used to check the chamber dimensions of rifles chambered in 5.56 NATO. It helps me determine if the chamber is still within safe functional limits or if it has worn beyond acceptable specifications. This gauge is crucial for maintaining firearm safety and performance.
Why I Needed a No Go Gauge
Over time, I noticed my rifle’s accuracy and cycling reliability started to decline. Using a No Go Gauge, I could quickly check if the chamber had stretched or worn out. It gave me peace of mind knowing I wasn’t risking a dangerous malfunction during shooting.
Key Features I Looked For
- Accuracy and Certification: I made sure the gauge was manufactured to exact SAAMI specifications or equivalent standards. This guarantees reliable and repeatable measurements.
- Durability: Since I use my tools regularly, I wanted one made from hardened steel that resists wear and corrosion.
- Compatibility: The gauge needed to be specifically designed for 5.56 NATO chambers, not just .223 Remington, as the dimensions differ slightly.
- Clear Markings: I appreciated gauges with laser-etched or engraved markings for easy identification.
Types of No Go Gauges I Considered
There are typically two types:
- Go/No Go Gauges: These come as a set where the “Go” gauge should fit the chamber and the “No Go” gauge should not. If the No Go gauge fits, it indicates excessive wear.
- No Go Only: Some sellers offer just the No Go gauge to check if the chamber has grown too large.
I personally opted for a full Go/No Go set to have a more comprehensive check.
Where I Found Reliable No Go Gauges
I checked well-known firearm tool manufacturers and verified customer reviews. Some brands stood out for consistent quality. I avoided cheap, unbranded gauges as accuracy is critical with these tools.
Price and Value Considerations
Prices varied from around $30 to over $100. I chose a mid-range option because I wanted both accuracy and durability without overspending. For me, this was a worthwhile investment given the safety implications.
How I Use My No Go Gauge 5.56
I follow these steps:
- Ensure the rifle is unloaded and safe to inspect.
- Insert the “Go” gauge—if it fits smoothly, the chamber is within minimum specs.
- Try the “No Go” gauge—if it fits, it’s a sign the chamber may be out of spec and needs inspection by a gunsmith.
Using the gauge regularly helps me monitor wear over time.
Final Thoughts
Buying a No Go Gauge 5.56 was a smart move for me to maintain my rifle’s safety and performance. If you’re serious about firearm upkeep, I highly recommend investing in a quality gauge and learning how to use it properly. It’s a simple tool that can prevent costly repairs or dangerous failures down the line.
