4 Fundamental Rules and Procedures for Safe Firearms Handling • Always treat every gun as if it were loaded! • Always keep the firearm pointed in a safe direction! • Always be sure the barrel is clear of any obstruction. • Always be sure of what lies beyond your target and the safety of bystanders before you shoot. • Always wear ear & eye protection when shooting. • Always carry your gun so that you can control the direction of the muzzle if you fall or stumble.
• Keep your finger off the trigger and leave the safety on until ready to shoot! • Make sure the Cam Pin is installed in the bolt group. If it isn’t, your rifle can still fire and will explode! • If your rifle stops firing with a live round still in the chamber (a misfire), quickly remove the round, keeping your face away from the ejection port. If you cannot remove it within 10 seconds, remove the magazine, and wait 15 minutes with the rifle pointed in a safe direction.
Facts About Your New Bushmaster Carbon 15 Firearm The Bushmaster Carbon 15 rifle/pistol system consists of a firearm, magazine, and instruction manual. It is a very light weight firearm; gas operated, magazine fed, and operates in semi-automatic mode (i.e., a single shot fired each time the trigger is pulled). 6 • Caliber is .223 Remington / 5.56mm • The upper and lower receivers are easily opened for cleaning and inspection.
Getting Ready to Shoot: • With the safety on, insert the loaded magazine into the magazine well, always making sure the muzzle is pointed in a safe direction! • Pull the charging handle fully to the rear. • Release the charging handle. Do not ride or push the charging handle. Let it move forward on its own. • Release bold catch • Move lever from safety to fire. • Note: If the rifle is not going to be fired immediately, make sure the selector lever is still on safe.
8 Immediate Action in Case of Trouble… If your rifle stops firing perform the following immediate actions… 1. Remove the magazine. 2. Pull charging handle all the way back. 3. Check chamber for any obstruction. 4. Insert the magazine and make sure it’s seated properly. 5. Pull the charging handle all the way back. RELEASE charging handle to feed a new round. Don’t ride the charging handle forward. 6. Now fire. If the rifle won’t fire, look for trouble and apply remedial action.
Remedial Action… If your rifle stops firing with a live round in the chamber of a hot barrel, remove the round fast. If this is not possible to remove within 10 seconds, remove the magazine and wait 15 minutes with rifle pointing in a safe direction (always make sure the safety stays on during that time). This will help prevent injury if a round fires as a result of a hot barrel. Keep your face away from the ejection port while clearing a hot chamber.
Bullet Stuck in the Bore… WARNING: If an audible “POP” or reduced recoil is experience during firing, IMMEDIATELY CEASE FIRE: Then: • Remove the magazine • Lock the bolt to the rear • Place the selector lever on SAFE • Check for a bullet in the bore Do not apply the “Immediate Actions” previously described. If a bullet is stuck in the barrel of the weapon, do not try to remove it. Take the rifle to a qualified gunsmith.
Disassembly Of Firearm… • Make sure firearm is not loaded and is pointed in a safe direction. • Remove magazine and clear the chamber • Open the bolt by pulling the charging handle completely to the rear while holding the charging handle in this position, use your other hand to lock the bolt in the rearward position by pushing the lower end of the bolt catch lever. • The bolt carrier should lock in the rearward position. Let go of the charging handle.
cause bodily injury. Next remove the buffer spring and buffer assembly by unscrewing the recoil tube on both the rifle and pistol. Use caution the buffer spring will be under pressure. • By using a small diameter drive tool, push both takedown pins from left to right until they stop. • Separate the receivers by holding the grip with one hand and pulling the upper receiver up and forward.
Cleaning: Clean the Bore… • Always clean from chamber to muzzle in the natural direction of the bullet. • Attach the three cleaning rod sections together, but leave each one about two turns short of being tight. • Attach the bore brush, leaving it two turns short of being tight. • Never run a brush down the barrel first or dip the brush in solvent. • Swab out the bore with a patch moistened with “CLP”. • Point muzzle down.
14 this will scratch the bore. About the 2 - 3 inches of the rod should protrude out of the muzzle end. • Attach the handle section of the cleaning rod to the threaded end that is sticking out of the muzzle. Diagram #1 • Pull the brush through the bore and out the muzzle.You should be able to see the rod twisting as you pull it. This is the brush “tracking” in the rifling. Never reverse the brush in the chamber. • After one pull, take the handle section off , and repeat the process.
Disassembly of Bolt Carrier Assembly… • Clean the bolt carrier assembly and components in a suitable cleaning solvent and remove any built-up carbon from the bolt. • Clean the rifle using a commercially available gun cleaner (WD-40 works well for cleaning exterior surfaces of the receivers.) Clean bore with bore brush and wipe out with cleaning patch. • Re-assembly is reverse of disassembly.
Disassembly of Bolt Carrier Assembly… 16 1. Push bolt into locked position 2. Remove firing pin retaining pin (Never Open or Close the Split End of Firing Pin Retaining Pin) 3. Drop firing pin out of rear of bolt carrier 4.
5. Remove bolt assembly from carrier. 6. Push extractor pin out Note: Press rear of extractor to check spring function. Remove extractor pin by pushing out with a punch, or the tip of a bullet. 7. Remove extractor and spring. Caution: Extractor spring may pop out and get lost. Bolt assembly should be disassembled only when dirty or damaged. Always replace damaged parts or see a qualified gunsmith.
18 Cleaning the Ejector… • The design of the ejector makes its disassembly for cleaning somewhat impractical (i.e., we don’t recommend it!). Make sure your firearm ejects empty cases efficiently by following these steps on a monthly basis (more frequently if firing blanks). • Remove the bolt from the carrier as described on previous pages. Hold it as shown with the ejector down and the extractor up. • Dribble a few drops of CLP around the ejector to form a puddle.
Inspection before lubricating… • Check the bolt: Look for cracks or fractures, especially in the cam pin hole area. Bolts with any pitting extending into the firing pin hole should be relaced. • Check the firing pin: If it is bent, cracked, too sharp, it should be replaced. • Check the firing pin retaining pin: If ti is bent or badly worn, it should be replaced. NEVER use a “Cotter Pin” as a substitute for a real firing pin retaining pin.
Lubrication… Upper and Lower Receivers: 20 Lightly Lubricate • The inside of the upper receiver, bore and chamber (using cleaning rod and patch). • The firing pin with CLP. • The charging handle and the inner and outer surfaces of the bolt carrier. Generously Lubricate • All moving parts inside the lower receiver (trigger, hammer, safety, bolt catch, etc), and all its various pins and detents. Don’t forget the takedown, pivot pins, and their detents. • The bolt, cam pin area, and bolt gas rings.
