First, assume the gun you are handling is loaded, and then proceed - according to the following steps - to CLEAR YOUR RIFLE… 1. Point Rifle in a SAFE DIRECTION! Place Safety Selector Lever on SAFE. NOTE: If the rifle is not cocked, the Safety Selector Lever cannot be pointed toward SAFE. 2. Press Magazine Catch Button and pull Magazine down to remove. 3.
0_Placed.qxd 12/28/07 3:30 PM Page 8 PREVENTATIVE MAINTENANCE CHECKS & SERVICES… CHECK BEFORE YOU FIRE! … 1. Check to see that there is NO EXCESSIVE OIL in the Bore. If there is, swab it out with a patch and the cleaning rod. ALWAYS CLEAN A NEW RIFLE BEFORE FIRING. WARNING! If the rifle is fired with oil - or water - in the barrel, excessive pressure will be created causing the rifle to explode. 2. Retract the Bolt to ensure free movement between Bolt Carrier and Gas Tube. 3.
0_Placed.qxd 12/28/07 3:30 PM Page 9 SAFETY FUNCTION CHECK… (Continued) 3. Place Selector Lever in FIRE position. Pull the Trigger. THE HAMMER SHOULD FALL. NOTE: For purposes of the following check, “SLOW” is defined as one fourth to one half the normal rate of trigger release. 4. Hold Trigger to the rear, pull Charging Handle to the rear and release Charging Handle. Then release pressure on the Trigger with a slow, smooth motion, without hesitations or stops, until the Trigger is fully forward.

0_Placed.qxd 12/28/07 3:30 PM Page 27 INSPECTION — CLEANING — LUBRICATION… AFTER FIRING YOUR RIFLE, clean it as soon as possible to make the job easier and to avoid allowing the development of any corrosion. When your firearm has not been fired, you should clean it at least once or twice a year if you live in a temperate climate, or as often as once a week in a tropical climate. If you get your firearm wet, clean it as soon as possible to avoid the onset of corrosion or rust.
0_Placed.qxd 12/28/07 3:30 PM Page 28 DETAILED CLEANING TECHNIQUES… NOTE: The procedures below describe cleaning with a standard military issue multi-piece rod cleaning kit. Other commercial cleaning kits may include alternate cleaning instructions which may be just as effective. CLEANING THE BORE: The bore of your Bushmaster rifle has Lands and Grooves called rifling. Rifling makes the bullet spin very fast as it moves down the Bore and down range.
0_Placed.qxd 12/28/07 3:30 PM Page 29 DETAILED CLEANING TECHNIQUES… (Continued) 6. After one pull, take off the handle section and repeat the process. After three or four pulls, the three rod sections and the Bore Brush may become screwed tightly together. Loosen them up and repeat the process. 7. Send a patch through the Bore occasionally to help clean out the crud that the brush is getting loose. Just replace the Bore Brush with the Rod Tip (Patch Holder) and a wet patch. Pull it through.
0_Placed.qxd 12/28/07 3:30 PM Page 30 CLEANING THE UPPER RECEIVER… NOTE: Check to ensure that there is no looseness between the Barrel and the Upper Receiver - if you detect any movement by twisting with your hands, the Barrel Nut must be retorqued. Bring the Rifle to your Gunsmith. 1. Using a “CLP“ type product, clean all areas (inside and out) of Powder Fouling, Corrosion and Dirt.

Be sure you lubricate in and around all the Locking Lugs (as in photo above). The Forward Assist should also be lightly lubed inside the Receiver and checked for function.
0_Placed.qxd 12/28/07 3:30 PM Page 35 LUBRICATION – BOLT CARRIER GROUP… Firing Pin: Lightly lubricate the Firing Pin with CLP - also the Firing Pin recess in the Bolt. Bolt: Generously lubricate the Bolt, its Cam Pin area, the Bolt Gas Rings. A lighter application is good on the Extractor and it’s Pin. Charging Handle: Lightly lubricate the Charging Handle and it’s Latch and Spring. Bolt Carrier: Lightly lubricate the inner and outer surfaces of the Bolt Carrier.
0_Placed.qxd 12/28/07 3:30 PM Page 36 LUBRICATION – ADJUSTABLE REAR SIGHT… NOTE: Record how far you move the Rear Sight so it can be returned to its original position upon the completion of this task.
