Figure 30. Use of Trigger and Hammer Gage.
NOTE
If the lower receiver is not disassembled, visually inspect for broken or damaged
parts, and to ensure that the hammer and trigger springs are correctly installed
before beginning this test. It is not necessary to disassemble the lower receiver for
the sole purpose of this visual inspection. If broken or damaged parts are found,
disassemble and repair as authorized.
5. Test two hammer pin holes and two trigger pin holes using no-go plug gage PN 12006472. This test
may be conducted by disassembly of the lower receiver or by pushing the pin far enough to disengage
the end of the pin from the side of the receiver which is being tested. If the lower receiver is not
disassembled and the no-go plug gage enters any hole to first shoulder (A), the lower receiver must be
disassembled and all four holes must be tested again.
6. Gently insert the no-go plug gage and rotate it 180 degrees. If the no-go plug gage passes into any one
of the four pin holes to the second shoulder (B), the weapon is unserviceable and will be turned in for
replacement.
7. After completion of gaging operation, visually inspect hammer and trigger springs to ensure proper
location of spring legs.
