CLYMER FIELD HEADSPACE GAUGES Reviews & Ratings

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.

Last Chance Gauge.

I already had the GO, and NO GO gauges, but had a 98 Mauser to check out, and the bolt closed on the NO GO. I could have used shims on the NO GO Gauge, to determine just how far out the head space was, but given the price of the FIELD GAUGE, it was better to buy one. The Brazilian Mauser's bolt would not close on the Field Gauge. I felt secure test firing the rifle, and fired cases entered a SAAMI Case Gauge easily, with no signs of a head space issue. The Clymer Gauge is beautifully made, and finished. It's a good investment.

Good product, good quality.

A good quality headspace gauge for.308 chambers.

Does just what it's supposed to

I bought this to round out my 30-06 gauges (already had Go & NO-GO). This is perfect for verifying the headspace on my M1 Garand(s)after bolt work. Unlike the dedicated gauges for a Garand, this does not have the cutout for the ejector, but it's no big deal to disassemble the bolt to check with this gauge, the reassemble the bolt. I also dropped this in my '03 Springfield for fun...
