Gather together the proper sized cleaning rod with a .223/5.56mm brass or bronze bristle bore brush and a slotted tip into which a cleaning patch can be inserted. Also needed are clean cloth patches and clean soft cloths. 2. Do not use stainless steel brushes on the weapon. Stainless steel brushes will remove the finish on the Ruger Mini-14 rifle. A bronze or brass "toothbrush" is especially helpful for scrubbing parts. Do not use the bore brush for scrubbing anything except the barrel. 3. Combat Arms and the United States military recommend that you use Break-Free CLP(TM). Under no circumstances should you ever use WD-40(TM) on any weapon! If you need a solvent, Combat Arms recommends that you use Shooter's Choice(TM) followed by CLP. The Ruger Mini-14 should be cleaned at least every 400 rounds (if the firing period is a long one) and after each firing period. 4. Using a cleaning rod with a slotted tip, run a CLP wetted patch through the full length of the barrel several times to remove loose material. Then attach a bronze or brass bristle bore brush to the cleaning rod and wet it in CLP. Run the bore brush back and forth through the full length of the barrel at least a dozen times. Make sure that the rod is pushed all the way through the barrel until the entire bore brush clears the muzzle end. Do not reverse the direction of the brush until it has completely exited from the muzzle end of the barrel or the bore brush may bind up inside the barrel. If there is metal fouling in the bore, remove it completely because metal fouling (lead or copper) can destroy the accuracy of the weapon. Please note that Hoppe's No. 9(TM) does not remove metal fouling as well as Shooter's Choice, in the opinion of many benchrest shooters. Combat Arms shares that opinion and recommends Shooter's Choice. If you want to remove copper fouling the fastest way, Combat Arms recommends that an uncontaminated bottle of Hoppe's No. 9 (meaning it has never been used before) be mixed in a 50-50 solution with 28% Aqua Ammonia. This is chemically known as AMMONIUM HYDROXIDE - 26øon the Baume' scale. This is potent stuff and is concentrated ammonia. It is three times more powerful than household ammonia. Do not use this inside a closed room! When poured down the barrel from the breech end (not the muzzle end!), the copper will be dissolved and fall out. It takes about 15 minutes. 5. Using the toothbrush soaked in CLP, scrub the area around the chamber until it is clean. Remove the bore brush from the cleaning rod and attach the slotted tip again. Run several dry patches through the barrel until they come out clean. If necessary, attach the bore brush to the cleaning rod again and scrub the barrel with a CLP soaked bore brush. Continue the process until the barrel is clean. 6. Failing to do this type of cleaning consistently and properly will cause fouling of the barrel with a natural loss of accuracy. Grease accumulation in the chamber area can interfere with the proper feeding of cartridges from the magazine. 7. Using a loose clean patch or soft rag soaked with CLP, remove all powder residue from all components of the mechanism. If grease or dirt cannot be removed by merely wiping with the patch, then use your brass toothbrush soaked with CLP. After using the brass toothbrush, wipe all of the scrubbed areas with a clean CLP wetted patch. After cleaning the bore, run a clean dry patch through the barrel and then follow it with a patch that has a light coat of CLP on it. This will put a light coat of CLP on the inside of the barrel and protect it from corrosion. 8. Wipe all surfaces with a clean cloth that has a light coat of CLP on it. If the lower receiver and its mechanism is especially dirty, flood it with CLP, leave it sit soaking for 2 hours and then flush it out with more CLP. Remove the grip panels before soaking or flushing the rifle and make certain that all foreign matter is removed after cleaning. Lightly lubricate the lower receiver with CLP. 9. When cleaning the bolt face, breech areas, etc. with the toothbrush, work carefully so as not to damage components. 10. Do not clean the gas port on the Mini-14. It is self cleaning. Also note that Chris Peters, in charge of Ruger's armorer training program, recommends that the gas pipe (piston) and the piston hole in the slide be thoroughly cleaned. Failure to thoroughly clean these areas may result in an accumulation of powder residue and moisture, which can result in a seizing of the gas piston to the slide. 11. Reassemble the rifle as detailed later in this manual. If the Mini-14 rifle is to be stored for an extended period, the final wiping should be done with a heavier coat of CLP. 12. Clean the internal and external parts of the disassembled magazine with CLP. The inside of the magazine can be cleaned with a soft rag or patch soaked in CLP. Remove all loose material with several clean patches, just like you did with the cleaning of the barrel. Leave a very light coat of CLP on the inside of the magazine and on the magazine spring.

Be very careful not to bend the magazine lips. º º º ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍͼ 13. Only a very small amount of CLP is needed to provide adequate lubrication of all moving parts in the Ruger Mini-14 and to prevent rust. Accumulation of CLP can attract particles of dust and dirt which can interfere with the safe and reliable function of the rifle. Do not, therefore, apply excess CLP unless storing the rifle for an extended period of time. If storing the weapon and using a heavy coating of CLP, the weapon should be disassembled and re-cleaned and lubricated with a light coating of CLP before firing.

Do not keep the rifle stored in a leather case º º or carrier. Leather attracts moisture, even though the carrier or º º case may appear to be perfectly dry. Never store the Ruger Mini-14 º º rifle in such a manner as it may be dislodged. Always store the º º rifle securely and unloaded. º º º ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍͼ ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ» º - LUBRICATION WARNING - º º º º Firing the rifle with oil, grease or any other material even º º partially obstructing the barrel may result in damage to the º º rifle and death or injury to the user and those persons nearby. º º Never spray or apply any lubricants directly to the ammunition. º º If the powder charge of a cartridge is affected by the lubricant, º º it is possible that the charge will not ignite but the energy º º from the primer in the cartridge case may be sufficient to push º º the bullet into the barrel where it may be lodged. Firing a º º subsequent bullet into the obstructed barrel may damage the rifle º º and cause death or injury to the user and persons nearby. Use all º º lubricants properly and according to the lubricant manufacturer's º º suggestions and recommendations. º º º ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍͼ - Acknowledgment of Trademarks - Combat Arms wishes to acknowledge the trademarks of the following products along with their respective companies.
