This Firewerks Headspace Gauge is for Mosin Nagant 7.62x54r military rifles. Package includes (1) No-go 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.
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.
Top Customer Reviews
If you purchase one of these old rifles, the small price of this gauge is well worth the peace of mind in knowing for sure that improper headspace is not going to cause you safety concerns down the road. I had an M-1 blow up on me back in the 60's due to improper headspace and believe me; learning first hand what 40 odd thousand psi can do outside the chamber is not a pleasant experience.
for me, my mosin nagant type 53 Chinese carbine is one of more favored rifles and im constantly taking it apart and cleaning it
and doing work to it. the headspace gauge is just an extra precaution I take when assembling my bolt to make sure the headspace is correct.
easy to use
a little pricey but no more than any other no-go gauge
tiny so its easy to get lost (but it has to be small, there is no getting around that)
I would buy again if I ever lost mine, I like having a secondary way to quickly check my headspace.
the no-go gauge is used differently than a go-gauge.
this particular gauge is to be placed with the notch lined with the extractor, then the bolt should be pulled forward and lock down slightly, if the bolt locks down all the way, the headspace is wrong, if it dosent budge at all, I would give it a little more space.
a go gauge is used the same way, but the bolt should close. don't get the two confused, youll end up having a mistake you probably wont dare make twice.
