DA Form 7523-R: Boresight Telescope Accuracy Test Guide – Accurate boresighting is critical for precision gunnery in the U.S. Army. The DA Form 7523-R (Boresight Telescope Accuracy Test) ensures that boresight telescopes and adapters deliver reliable alignments for weapon systems on platforms like the Bradley Fighting Vehicle and other armored assets.
What Is DA Form 7523-R?
DA Form 7523-R, dated September 2003, is an official U.S. Army form titled “Boresight Telescope Accuracy Test.” It standardizes the testing of boresight telescopes and associated adapters to verify they meet accuracy requirements (typically 1 mil or less deviation).
The form supports training and maintenance procedures outlined in field manuals such as FM 3-22.1 (Bradley Gunnery) or FM 3-20.21 (Heavy Brigade Combat Team Gunnery), with TRADOC as the proponent agency.
Key Sections on the Form:
- Header Information: Date, time, test type, telescope number, adapter number, kit, and unit.
- Test Grids: For right and left aim points, recording azimuth (AZ) and elevation (EL) coordinates in inches and mils.
- Scoring: GO/NO-GO based on distance between aim points (pass requires 1 mil or less).
- Inch-to-Mil Conversion Chart: For quick field calculations.
- Overall Pass/Fail: Requires passing both tests.
Why Is the Boresight Telescope Accuracy Test Important?
Boresight telescopes align weapon systems (main guns, machine guns, etc.) with sighting devices without live firing. Inaccurate telescopes lead to:
- Missed targets
- Wasted ammunition
- Reduced crew confidence and combat effectiveness
- Safety risks during gunnery qualifications
Regular accuracy testing with DA Form 7523-R maintains equipment readiness, supports gunnery tables, and complies with Army training standards for units operating armored vehicles.
Step-by-Step Guide to Conducting the Test
- Preparation — Gather the boresight telescope, adapter, test target/aim points, and a blank DA Form 7523-R.
- Setup — Mount the telescope and adapter per the applicable technical manual or FM.
- Test Execution:
- Align to the right aim point and record coordinates (AZ/EL).
- Align to the left aim point and record coordinates.
- Calculate the distance between points in inches and convert to mils.
- Scoring — Compare against the 1-mil threshold. Record GO/NO-GO for each test.
- Documentation — Complete tester details, unit info, and overall results. Retain records for maintenance tracking.
Pass Criteria: Both tests must show 1 mil or less deviation for overall PASS.
Who Uses This Form?
- Bradley Crews and other armored vehicle operators
- Master Gunners and gunnery instructors
- Unit armorers and maintenance personnel
- Training commands conducting crew qualification or sustainment training
It is especially relevant for Heavy Brigade Combat Team (HBCT) and similar formations.
