Gauge Specifications.

This document outlines the specifications for headspace gauges for the following calibers:

CALIBER "F" (GO- MINIMUM) ) +.0002 (inches) "F" (FIELD MAXIMUM) ) -.0002 (inches) DIAMETER "M" BASIC

6.5 Creedmoor 1.541 1.551 .400

7.62 x 39 1.252 1.262 .3662

7.62x51 (NATO) 1.6300 1.6400 .400

*see SAAMI reference drawing at the end of this document*

** SAAMI reference for 300 Winchester magnum at the end of this document "Belt Breech". Winchester magnum Diameter on the reference drawing is "G".

1. Headspace Dimensions:

- Go Gauge (Minimum Headspace): SAAMI or NATO MINIMUM headspace dimension +0.0002" tolerance. - as applicable (See Caliber)

- Field Gauge (Maximum Headspace): SAAMI or NATO MAXIMUM headspace dimension -0.0002" tolerance. - as applicable (See Caliber)

- Diameter Requirements: Gauges must conform to SAAMI or NATO diameter specifications at both the MINIMUM (Go Gauge) and MAXIMUM (Field Gauge) headspace distances.

2. Material and Hardness:

- Material: High-alloy tool steel AISI O1 or O2.

- Heat Treatment: SAAMI Heat treated to a Rockwell Hardness of 50-60 HRC.

3. Geometric Tolerances:

- Perpendicularity: The critical surfaces of the gauge (e.g., datum surfaces to gauge faces) must be perpendicular within 0.0002" Total Indicated Reading (TIR).

4. Surface Finish:

- Surfaces: All bearing surfaces (i.e., surfaces that contact the chamber) must have a surface finish of 16 microinches Ra (Roughness Average) or better. All other surfaces must have at minimum surface finish of 32 microinches Ra or better.

5. Labeling:

- Each gauge must be permanently and clearly labeled with the following information:

- "SAAMI MINIMUM (GO)" "NATO MINIMUM (GO)" - as applicableOR

- "SAAMI MAXIMUM (FIELD)" "NATO MAXIMUM (FIELD)" - as applicableOR

- Nominal headspace dimension (e.g., "1.6300")

- Caliber (e.g., "5.56x45mm")

- Manufacturer's identification (e.g., serial number or Gauge unique Identification number to match certification)

6. Certification and Calibration:

- The certification must be performed by an ISO/IEC 17025, ANSI/NCSL Z540.1 or Z540.3 accredited laboratory , with measurements traceable to NIST, and the final certificate must include the calculated measurement uncertainty. The vendor must provide third-party certification for the following critical dimensions, verified to tolerances per applicable SAAMI or NATO specifications:

- Go Gauge (Minimum Headspace dimension) + .0002"

- Field Gauge (Maximum Headspace dimension) -.0002"

- Perpendicularity

- Diameter

- The certification report must include:

- Gauge identification (serial/lot number)

- Date of certification

- Calibration laboratory name and accreditation information (e.g., ISO 17025)

- List of instruments used for certification (including calibration dates)

- Measurement data for each critical dimension

- Statement of conformity to SAAMI or NATO specifications

- Signature and title of the certifying technician.

7. CAD Drawings:

- The vendor must provide a complete and accurate CAD drawing for each gauge, including:

- All critical dimensions and tolerances

- Material specifications

- Heat treatment specifications

- Surface finish requirements

- Datum surfaces

- Revision level

8. Packaging and Storage:

- Individual Packaging Required: Each gauge be individually packaged in a labeled, durable storage container to protect it must from damage during shipping and storage and to facilitate proper storage of the gauges when not in use.

- Container Requirements: The storage container must be appropriate for the gauge size and weight and made of a material that will not damage the gauge (e.g., a rigid plastic case with foam padding).

- Labeling: The label on the storage container must match the information on the gauge.
