U.S. M14/M14A1 7.62mm Rifle Combination Tool, P/N 7790769
Item Overview
This U.S. military Combination Tool, part number 7790769, was issued for the 7.62mm M14 and M14A1 rifles. Its compact design combines several maintenance functions in one portable accessory. The Army listed it with the rifles’ cleaning equipment under Federal Stock Number 4933-768-0211. The tool supported routine cleaning, adjustment, disassembly, and assembly without requiring several separate tools. It is a maintenance accessory rather than an installed rifle component.
Identification and Features
Army technical manuals identify this item by the official nomenclature “Combination Tool” and part number 7790769. Its design includes a tubular steel body, large circular openings at one end, a socket-type opposite end, and a folding screwdriver blade held by a spring pin. These features match the exploded view in the Army’s 1972 direct-support maintenance manual. The original 11-digit Federal Stock Number can also be written in the later 13-digit NSN format as 4933-00-768-0211.

Function and Operation
The combination tool gave the rifleman a compact way to complete several maintenance tasks on the M14 family. Army instructions document its use during bolt servicing and for working attachment hardware associated with the M2 rifle bipod and M14A1 muzzle stabilizer. The operator’s manual specifically directs the user to tighten the self-locking bolt that clamps the M2 bipod jaws around the rifle’s gas cylinder with this tool. Its folding screwdriver blade stores against the body when not in use, reducing the tool’s size for storage with the rifle’s cleaning equipment.
End-Item Application
The M14 is a gas-operated, air-cooled rifle chambered for the 7.62×51mm NATO cartridge and fed by a detachable 20-round magazine. It can fire in semiautomatic or automatic mode when fitted with the proper selector equipment. The M14A1 adapted the same basic action to the automatic-rifle role. It used an in-line pistol-grip stock, folding shoulder rest, forward handgrip, M2 bipod, and muzzle stabilizer to improve support and control during automatic fire. Part number 7790769 is documented for the maintenance equipment supplied with both rifle configurations.
Historical Background
The M14 grew from the U.S. Army’s post-World War II search for a standard rifle based on the proven M1 Garand operating system. Selected in 1957, it introduced the NATO-standard 7.62mm cartridge and a detachable 20-round magazine. The Army intended the rifle family to cover duties previously divided among the M1 rifle, M2 carbine, M3 submachine gun, and Browning Automatic Rifle. The M14A1 extended the design into the squad automatic-rifle role. The combination tool was part of the support equipment developed to help soldiers maintain these rifles with a small number of portable tools.
History of Use
The M14 became a standard U.S. military rifle during the early 1960s and accompanied American forces during the opening years of the Vietnam War. The M14A1 served as an automatic-rifle configuration during the same period. The lighter M16 gradually replaced the M14 in general infantry service, but M14-family rifles continued in training, ceremonial, competition, security, and specialized marksman roles. As listed rifle cleaning and maintenance equipment, the combination tool supported routine care in armories, on training ranges, and under field conditions.
