Product Description

This Firewerks Headspace Gauge is for Mosin Nagant 7.62x54r military rifles. Package includes (1) Field Gauge.

Firewerks Headspace Gauges are made from high quality stainless steel for corrosion resistance, heat treated for wear resistance, and precision ground for superb accuracy.

SUPERIOR QUALITY
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.

PRECISION ACCURACY
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.

I have to give this product the two thumbs up award. It is easy to use, and it is a great quality product. I personally like the Mosin Nagant rifles, and before firing a new old stock rifle, it is extremely important to check the head spacing. With this product, the head spacing can be checked in less then a minute. I use a lot of military surplus ammo through my rifles that is why I went with a field grade gauge. I would recommend this product, and I will personally be puchasing more just in case I lose this one. Also, Firewerks got this product to me very fast with normal shipping speed. I would recommend this company.

So, I dont really get why a little metal dime sized disc costs $25. However, looking at similar offerings (which are in the same price point), this works without having to remove the extractor on the bolt. So you can test a gun pretty quick.

Very well machined. Used mine over a hundred times on both Russian and Finnish made Mosins. If you're a fan of safety, and want to walk away with a Mosin that's not going to hand grenade on ya, this is the Item to buy. Keep a light coat of oil on it and it will last an eternity. A++ item.

I bought 3 Mosin-Nagant rifles on the internet and wanted to make sure they were shootable before I accepted delivery. This product let me know right away, that all 3 rifles were ready for the range. Simple, quick, easy to use, AND you don't have to remove the extractor from the bolt using this product. Saves time and money(as compared to other brands of gauges). Cant go wrong with that!

As an instructor at a local range,I was amazed of the lack of awareness of individuals who want to fire WWII weapons without having their weapons checked for headspace,and other possible problems.With this gauge I am able to check the headspace of the Mosin Nagant rifles quickly without having to remove the extractor. Even though a rifle may pass this quick test for excessive headspace-all weapons from this era should be checked by a competent gunsmith for safety sake.

The importance of checking headspace on a firearm, especially a military surplus like a Mosin that this fits it critical, so anyone who purchases one should buy one of these to ensure its safety. The big plus to this gauge over others is that you do not need to remove the extractor which is quite difficult on the Mosin bolt. It was very simple to use, came with clear instructions and gave me piece of mind firing the weapon.

It works. Not sure what else to say. The rifle has been fired after I bought it and nothing blew up in my face. The quality of the machining on the gauge is very good, but it's easy to lose it, so be careful.
