Cleaning Weapons Received From Storage

Carbines are received from storage with a coating of preservative lubricating oil or of rust-preventive compound. Carbines received from ordnance storage will usually be coated with rust-preventive compound. Use volatile-mineral-spirits-paint thinner or dry-cleaning solvent to remove all traces of the compound or oil. Take particular care that all recesses in which springs or plungers operate are cleaned thoroughly. Failure to do this may cause stoppages at normal temperatures and will certainly cause stoppages when the rust-preventive compound freezes during cold weather-After using the cleaning solvent, be sure it is completely removed from all parts by wiping with a dry cloth. Then apply a thin coat of preservative lubricating oil to all metal parts and use linseed oil on the wooden parts.


a. If a chemical attack is expected or chemical contaminations are encountered, the following action should be taken: Apply oil to all outer metal surfaces of the carbine and accessories. Do not apply oil to ammunition. If the carbine is not to be used, cover it, the accessories, and the ammunition with protective coverings or disperse them under natural cover. Ammunition should be kept in its containers as long as possible. After a chemical attack, determine by means of detector paper (for liquid) or detector crayon (for vapors) whether or not the equipment is contaminated.

b. If uncontaminated, clean the equipment with a dry-cleaning solvent. Prepare it for use as required.

c. If contaminated, a complete suit of protective clothing (permeable or impermeable), including impermeable protective gloves, and a gas mask must be worn during decontamination.

(1) Equipment contaminated with chemicals other than the blister agents or G-series agents can be decontaminated by airing. For faster decontamination of this equipment and to protect against corrosion, clean the carbine and its equipment with rifle bore cleaner, denatured alcohol, or soap and water.

(2) Equipment contaminated by blister agents will be decontaminated as follows:

(a) Remove dirt, dust, grease, and oil by wiping with rags.

(b) Expose all surfaces to air.

(c) Decontaminate all metal surfaces except the bore with agent, decontaminating, noncorrosive (DANC) (FM 21-40). Hot water and soap, or repeated applications with gasoline soaked swabs are also effective.

(d) Protective ointment, M5, carried in the gas mask carrier, can be used for emergency decontamination (FM 21-40). {e) Test with detector paper or detector kit to see if decontamination is complete.

(f) After decontamination and tests are complete, clean, dry, oil, and prepare the carbine and its equipment for use as required.

(g) Burn, or preferably bury, all rags or wiping materials used during decontamination. Caution should be taken to protect men against vapors created by burning.

(3) In general, these same actions are applicable to equipment contaminated by biological or radiological attack. If contamination is too great, it may be necessary to discard the equipment. Detailed information on decontamination is contained in FM 21-40 and TM 3-220.


a. In Cold Climates. In temperatures below freezing, the moving parts of your carbine must be kept absolutely free from moisture. Also, excess oil on the working parts will solidify to such an extent as to cause sluggish operating or complete failure.

(1) The carbine should be disassembled and completely cleaned with volatile-min-eral-spiritspaint thinner or dry-cleaning solvent before use in temperatures below 32 degrees F. The working surfaces of parts which show signs of wear may be lubricated by rubbing with a cloth which has been wetted in special preservative lubricating oil; other parts are left dry. At temperatures above 32 degrees F., all metal surfaces of the carbine may be oiled thinly, after cleaning, by wiping with a lightly oiled cloth using the medium preservative lubricating oil.

(2) When brought indoors, the carbine should first be allowed to come to room temperature. Moisture will condense on the cold surfaces. Then disassemble the carbine and wipe it completely dry. Oil with the special preservative lubricating oil. This condensation may be avoided by providing a cold place in which to keep the carbine when not in use. For example, a separate cold room with carbine racks may be used, or, when in the field, racks under proper cover may be improvised. If the carbine has been fired, it should be cleaned and oiled. When the carbine reaches room temperature it should be cleaned and oiled again, b. Hot, Humid Climates. In tropical climates where temperature and humidity are high, or where salt air is present, and during Tainy seasons, your carbine should be inspected thoroughly every day. It should be kept lightly oiled when not in use. The carbine should be field stripped at regular intervals and if necessary, should be disassembled enough to permit the drying and oiling of all parts. Care should be taken to see that unexposed parts and surfaces are kept clean and oiled. Medium preservative lubricating oil should be used. Wood parts should be inspected to see that swelling caused by moisture does not bind working parts. If swelling has occurred, shave off the wood only enough to relieve binding. A light coat of raw linseed oil applied at intervals and rubbed in with the heel of the hand will help to keep moisture out. Allow the oil to soak in for a few hours and then wipe and polish the wood with a dry clean rag. Care should be taken that linseed oil does not get on the working parts, because linseed oil thickens when dry. Stock and hand guards should be dismounted while this oil is being applied.

c. Hot, Dry Climates. In hot, dry climates where sand and dust are likely to get into the mechanism and bore, the carbine should be wiped clean daily or oftener. Groups should be separated and disassembled for thorough cleaning. When the carbine is being used under sandy conditions, all lubricants should be wiped from the weapon. This will prevent sand from sticking to the lubricant and forming an abrasion which will ruin the mechanism. Upon leaving sandy terrain, the carbine should be cleaned and relubricated. In such climates, the wood parts are likely to dry out and shrink. A light application of raw linseed oil will help to keep the wood in condition. Since perspiration from the hands contains acid and causes rust, it should be wiped from all metal parts. During sand or dust storms, the receiver and muzzle should be kept covered if possible.
