Description
Technical Manual (TM 9-1240-242-34P) for M9 and M9A1 Telescope Adapters March 1971
This Technical Manual TM 9-1240-242-34P covers the M9 and M9A1 Telescope Adapters and is dated March 1971.
The publication is a direct support and general support maintenance repair-parts and special-tools reference for these U.S. Army fire-control adapter assemblies.
Historical Significance
The M9 and M9A1 Telescope Adapters served as components within the Army's M34-series sight units, helping integrate optical sighting equipment used with mortar fire-control systems. M34-series sight equipment supported weapons that included the 81 mm M29/M29A1 mortar and the 4.2-inch M30 mortar.
Issued during the Army's transition to direct-support and general-support maintenance terminology, this 1971 parts manual replaced the earlier TM 9-1240-242-35P dated July 17, 1962. It documents the later supply and maintenance organization used to sustain these established optical assemblies.
M9 and M9A1 Telescope Adapter Applications
The telescope adapter was not a stand-alone sight. It formed part of an assembled fire-control sight unit, providing the mechanical interface and adjustment structure associated with the optical components. The M9A1 is specifically identified as part of the M34-series sight unit.
For researchers and restorers, this relationship places the manual in the broader context of Army mortar sighting equipment rather than general-purpose observation optics.
What This Manual Covers
This -34P repair-parts and special-tools manual organizes support information for the M9 and M9A1 Telescope Adapters at direct support and general support maintenance levels. Its introduction explains the parts-list columns, special information, abbreviations, manufacturer supply codes, and methods for locating repair parts.
The illustrated parts coverage is arranged around the adapters' holder assemblies, housing assemblies, and azimuth-worm components. The publication also includes special tools, test and support equipment, plus a Federal Stock Number and reference-number index cross-referenced to figure and item numbers.

Why This Manual Matters
TM 9-1240-242-34P preserves the official Army nomenclature, stock numbers, assembly identifiers, and illustrated-parts organization needed to identify components of the M9 and M9A1 adapters. That level of detail is especially useful when loose optical parts or incomplete sight-unit assemblies must be identified.
The manual also connects the adapters to the M34-series fire-control system and records the maintenance supply structure behind mortar sighting equipment that is often encountered without complete documentation.
About This Manual
