What is the CLYMER - CLYMER FIELD HEADSPACE GAUGES?

CLYMER FIELD HEADSPACE GAUGES

The Clymer Field Headspace Gauges are essential tools for gunsmiths and firearm enthusiasts, designed to measure the absolute maximum allowable safe chamber headspace in rifles. These gauges are particularly useful when assessing used firearms to ensure they meet safety standards.


Key Features:

  • Precision Measurement: Clymer gauges are machined from high-quality steel and adhere to SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) specifications, ensuring accurate and reliable measurements.

  • Safety Assurance: If a rifle's bolt closes on a Field gauge after closing on a No-Go gauge, the firearm is considered unsafe to shoot. In such cases, the barrel may need to be set back and rechambered to restore safe headspace dimensions.

  • Caliber Compatibility: Available for popular calibers, including .308 Winchester and .30-06 Springfield, making them versatile for various rifle assessments.

Specifications:

  • Material: Machined steel

  • Standards: Manufactured to SAAMI specifications

  • Caliber Options:

    • .308 Winchester (also fits .243, .260, 7mm-08, .338 Federal, and .358 Win)
    • .30-06 Springfield (also fits .25-06, .270 Win, 8mm-06, .338-06, and .35 Whelen)

Customer Insights:

Our customers frequently praise the Clymer Field Headspace Gauges for their precision and reliability. Many highlight the clearly etched "Go" or "No-Go" markings and caliber names on the gauges, which make identification simple and efficient. The included durable plastic storage case is also valued for protecting and organizing the gauges, ensuring they remain in excellent condition.


Adding Clymer Field Headspace Gauges to your firearm maintenance toolkit guarantees that your rifles operate within safe headspace parameters, enhancing both safety and performance.

Just What I Needed
Nice field gauge for measuring the max allowable headspace on my M1 Garands. This was recommended over other brands for its precision and quality. Works perfect for a final headspace check for vintage rifles that may fail the no-go test.

You need this if you have the go nogo
I purchased the go and nogo set. seems like this Field gauge should be part of a 3 oc set to begin with. The go gauge, well you can do qithout unless you cut your own chambers. I get that, but a nogo and a Field gauge are a must. because if you cant chamber a round then thats that. but if you can chamber a round and the chamber is way too long then you could have a nasty failure..so the Field gauge and nogo should be the set..or all three. 99.00 for all three is a no brainer for the peice of mind when checking exiating firearms amd or putting together an AR platform. its good to test to make sure a barrel and an extention did not sneak by QC.
