Firewerks Headspace Gauges are made from high quality stainless steel for corrosion resistance, heat treated for wear resistance, and precision ground for superb accuracy.
Firewerks headspace gauges are the original and only coin-style gauges on the market that are made from stainless steel for superior corrosion resistance. Manufactured right here in the USA, Firewerks headspace gauges are precision built and made to last.
Every single gauge is precision ground to very tight tolerances with top of the line machines. Then, each gauge is double checked by hand with micrometers before it ever gets packaged and leaves our shop.
SIMPLE TO USE!
As easy as 1-2-3. These high quality stainless steel Go, No-go, and Field headspace gauges are specially designed so that you don't have to remove the extractor to check your rifle's headspace.
EASY TO IDENTIFY
Easily identify which gauge is which with the laser etched letter identifiers - "G" (go gauge), "N" (no-go gauge), "F" (field gauge). Now you no longer have to guess what gauge you are looking at.
What is Headspace?
In simple terms, headspace is the clearance allowed between the base of the cartridge case and the face of the bolt. Too little headspace and the bolt may not function correctly. Too much headspace may cause ruptured cases that can harm the gun and may cause personal injury and/or death. When purchasing a used firearm, it is very important to always check the headspace before firing it - especially surplus military rifles! Military surplus rifles have had thousands of rounds put through them and were often exposed to harsh use. You never know what kind of condition your gun may be in. It's best to play it safe and check the headspace.
