About Your Bushmaster 9mm Pistol or Carbine…

  • This Operating Manual covers all Bushmaster Carbon 15 9MM models chambered for 9MM NATO (9MM x 19MM) ammunition. They are lightweight, blow-back operated, magazine-fed pistols or carbines that are Semi-Automatic in operating mode (i.e., a single round will fire each time the trigger is pulled). For Law Enforcement and Military markets, Bushmaster makes similar models in Full-Automatic operating mode (continuous fire as long as the trigger is pulled). Sales of these models require special permits and are regulated by ATF.
  • The Upper and Lower Receivers are easily opened for cleaning and inspection. They are injection molded from Carbon Fiber  Composite for light weight, durability and are completely impervious to corrosion or damage from water.
  • Bushmaster 9MM Models feature Dual Aperture Rear Sights adjustable for windage, and A2 Square Post Front Sights adjustable for elevation.
  • Barrels on Carbon 15 9MM Models are Chrome Moly Vanadium Steel – button rifled – 1 turn in 10” with a right hand twist - 6 lands and grooves. Pistol Barrel length is 7.25” / Carbine Barrel length is 16”.
  • Pistol models have an oval Carbon Fiber Forend with a special ergonomic grip derived from the M203 Grenade Launcher and the Receiver Extension tube on Pistols is covered with comfortable, sound deadening Neoprene Foam Tube. Carbine models are  configured with a 6 Position Telescoping Buttstock. Forends are of removable split design and are vented to allow heat dissipation. All models feature vertical pistol grips and detachable magazines. Magazine capacity is 30 Rounds in factory supplied magazine.

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 FIREARM BEFORE FIRING.
    WARNING!
    If the Firearm is fired with oil - or water - in the barrel, excessive pressure will be created causing it to explode.
  2. Retract the Bolt to ensure free movement between Bolt and Receiver.
  3. Perform Safety Function Check (below) to ensure that Safety Selector Lever works properly.

SAFETY FUNCTION CHECK…

UNLOAD FIREARM - REMOVE MAGAZINE - CHECK CHAMBER

  1. Remove Magazine if installed. Pull Charging Handle assembly to rear. Check that Chamber is clear. Let the Bolt close. Do not pull Trigger. Leave Hammer in cocked position.
    WARNING: If the Firearm fails any of the following tests, continued use of it could result in injury to, or death of, people around you.
  2. Place Selector Lever in SAFE position, point Firearm in a safe direction, and pull Trigger.
    9mm_safety_selector_safe.png
    THE HAMMER SHOULD NOT FALL.
  3. Place Selector Lever in FIRE position. Pull the Trigger. THE HAMMER SHOULD FALL.
    9mm_safety_selector_fire.png
    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.
    AN AUDIBLE CLICK SHOULD BE HEARD - THE HAMMER SHOULD NOT FALL.
  5. Repeat the FIRE position test FIVE TIMES. The Firearm must not malfunction during any of these five tests. If the Firearm malfunctions during any of these five tests, have it checked by a qualified gunsmith.

PREPARING TO FIRE - LOADING A MAGAZINE…

  1. Use only quality 9MM NATO (9mm x 19mm) Ammunition suitable for your firearm. Examine each Cartridge - particularly around the primer. Look for dents, scratches, and other signs of damage.
    DO NOT LOAD DAMAGED AMMUNITION!
  2. With the Magazine facing forward, place a Round between the Feed Lips of the Magazine with the Bullet Tip forward. Push the Round down until it is held by the Magazine Feed Lips.
  3. If necessary, give the Round a slight push backward to seat it against the inside back edge of the Magazine Feed Lips. Place next Round on top of the previous Round and repeat steps until desired number of Rounds are loaded into Magazine.
    CAUTION: Safe Firearms Handling dictates that you ONLY LOAD LIVE AMMUNITION INTO YOUR FIREARM WHEN YOU ARE ABOUT TO SHOOT.

OPERATION OF YOUR FIREARM… LOADING

CAUTION: ALWAYS POINT THE MUZZLE IN A SAFE DIRECTION!

  1. With the Hammer cocked, place Selector Lever on SAFE.
    9mm_safety_selector_safe.png
  2. Pull Charging Handle back to open Bolt and check Firing Chamber. Make sure it is CLEAR! With no Magazine in the gun, the Bolt will not lock to the rear unless Bolt Catch is manually engaged as described on Clearing Your 9MM Pistol or Carbine.

INSERTING A MAGAZINE…

  1. Return Charging Handle to forward, locked position. Push a Magazine up into Magazine Well until Magazine Catch engages and holds the Magazine.
  2. Then, slap upwards on Magazine bottom to make sure it is seated correctly.
    9mm_slap_magazine_9.png
    NOTE: A Magazine may be inserted into the Firearm with the Bolt Assembly either Open or Closed.

CHAMBERING A ROUND FROM AN OPEN BOLT… (i.e. Bolt locked back)

  1. Depress upper portion of Bolt Catch. Bolt should spring forward. This will chamber a round from the Magazine.
    9mm_bolt_catch_10.png
    CAUTION: FIREARM IS NOW LOADED – READY TO BE AIMED AND FIRED!

CHAMBERING A ROUND FROM A CLOSED BOLT…

  1. With a Magazine inserted in the Firearm, pull the Charging Handle fully to Rear.
    Then release the Charging Handle allowing the Bolt to spring forward - chambering the first round.

9mm_charing_handle_10.png

NEVER “Ride” or push the Charging Handle forward. Let it move forward on its own.

CAUTION: FIREARM IS NOW LOADED – READY TO BE AIMED AND FIRED!

OPERATION OF YOUR FIREARM... (Continued)

CONDITION: Firearm is now Loaded, a Round is Chambered, and Safety Selector should be on SAFE.
CAUTION: ALWAYS POINT THE MUZZLE IN A SAFE DIRECTION!

To FIRE the Pistol/Carbine in SEMI-AUTOMATIC MODE (one Round fired with each pull of the Trigger), move the Safety Selector from SAFE (S) to FIRE (F)

9mm_safety_selector_fire_11.png

AIM AT TARGET – PULL TRIGGER – RELEASE.

The Firearm will automatically eject the spent Cartridge and chamber another in preparation for the next shot. The cycle of pulling the
Trigger to shoot, and the Firearm automatically reloading, can be continued until the Magazine is empty.

To FIRE the Pistol/Carbine in FULL-AUTOMATIC MODE (continuous fire as long as Trigger is held back), move the Safety Selector from SAFE (S) to AUTO (A).

9mm_safety_selector_auto_11.png

AIM AT TARGET – PULL AND HOLD BACK TRIGGER.

The Firearm will fire automatically and continue to do so, until either the Magazine is depleted, or the Trigger is released. If Magazine is not depleted, automatic fire can be resumed by pulling and holding back Trigger again. When Magazine is empty, the Bolt Carrier will lock to the rear.

alert.pngWARNING… IF A NOTICEABLE DIFFERENCE IN SOUND OR RECOIL IS EXPERIENCED, STOP FIRING.

Either condition could indicate an incomplete powder burn and/or a bullet stuck in the bore. Retract the Bolt slowly and remove the fired cartridge case. Clear the weapon and check for unburned powder grains in the Receiver or Bore, and for a Bullet stuck in the Bore. Clean out any unburned powder before resuming firing. If a Bullet is stuck in the Bore, do not attempt to remove it. Take the Firearm to a qualified Gunsmith.

IMMEDIATE ACTIONS — IN CASE OF TROUBLE!

IF YOUR RIFLE/PISTOL STOPS FIRING: Perform the following IMMEDIATE ACTIONS…

  1. SLAP upward on Magazine to make sure it is properly seated.
  2. PULL Charging Handle all the way back. Observe the ejection of the Case or Cartridge. Check Firing Chamber for any obstruction.
    alert.pngWARNING… DO NOT LOAD WITH A HOT CHAMBER – A ROUND MAY “COOK OFF”.
    “Cooking Off” means that a Round may Detonate (Fire) unexpectedly just from being exposed to the heat existing in the Gun’s Firing Chamber.
  3. If Cartridge or Case is ejected, or Chamber is clear, RELEASE Charging Handle to feed a new Round. Don’t “ride” the Charging Handle forward.
  4. Now FIRE. If the Rifle/Pistol will not fire, look for trouble and apply the Remedial Actions described next.

REMEDIAL ACTIONS…

alert.pngWARNING: IF YOUR FIREARM STOPS FIRING WITH A LIVE ROUND IN THE CHAMBER OF A HOT BARREL, REMOVE THE ROUND FAST. If you cannot remove it within 10 seconds, remove the magazine and wait 15 minutes with the Firearm pointing in a safe direction. This way you and those around you won't get hurt by the possibility of a round “cooking off”.

KEEP YOUR FACE AWAY FROM THE EJECTION PORT WHILE CLEARING A HOT CHAMBER.

  1. If your Firearm still fails to fire after performing Immediate Action Steps above, check again for a jammed cartridge case.
  2. If a cartridge case is stuck in the firing chamber, open the receivers, remove the bolt, and try to tap out the case with a cleaning rod. IF THE FIREARM STILL FAILS TO FIRE, CHECK THE TROUBLESHOOTING SECTION IN THIS MANUAL – OR TAKE IT TO A QUALIFIED GUNSMITH FOR INSPECTION.

DISASSEMBLING YOUR 9MM PISTOL/CARBINE…

  1. CLEAR THE FIREARM! Remove Magazine and any Accessories or Sling for convenience.
  2. Push in Takedown Pin (a punch or other pointed tool can help) as far as it will go. Pivot Upper Receiver from Lower Receiver.
    9mm_takedown_pin_13.png
  3. Push in Pivot Pin (a punch or other pointed tool can help).
  4. Separate Upper and Lower Receivers.
    9mm_separated_receivers_13.png
  5. Pulling Charging Handle back will bring Bolt out of Upper Receiver.
  6. Completely remove Bolt from Upper Receiver (easiest if Upper Receiver is inverted).
    9mm_bolt_upper_receiver_13.png
  7. Then remove Charging Handle from Upper Receiver by pulling back until “Ears” on the Handle’s shank clear the cutouts in Receiver.
  8. Remove the Firing Pin Retaining Pin from the Bolt. A punch or other pointed tool can help push it out far enough to grasp from left side.
    9mm_firing_pin_retaining_pin_14.png9mm_punch_14.png
  9. Firing Pin is spring loaded, so once Firing Pin Retaining Pin is removed, Firing Pin should pop out of Bolt. If carbon or powder residue is preventing free movement of Firing Pin, turn bolt on end and tap on a hard surface to free it.
    9mm_firing_pin_spring_14.png
    Do Not open or close split end of Firing Pin Retaining Pin, and Do Not substitute a common cotter pin on reassembly.
  10. With Hammer cocked, depress Buffer Retainer with punch or Bullet tip to release Buffer and Spring.
    9mm_magazine_well_15.png
    CAUTION! Buffer is under tension from Action Spring.
    NOTE: Hammer needs to be cocked to allow Buffer and Spring to clear Receiver.
  11. Pull out Buffer and Action Spring for cleaning.
    NOTE: Carbine Receiver shown here - Pistol is similar.
    9mm_buffer_action_spring_15.png
    9mm_buffer_buffer_retainer_15.png
  12. Due to the powder and carbon residues left in the blow back action, it may be necessary to clean the Magazine Well, the interior of Lower Receiver and the Magazine Well Insert periodically. The Insert can be removed from the Lower Receiver by removing the Bolt Catch and a Front Roll Pin.
    9mm_mag_well_16.png
  13. To remove the Bolt Catch, carefully drive the Bolt Catch Roll Pin to the rear with a small punch and hammer. Take care not to damage the Receiver protrusions that are drilled for this Pin. Remove the Bolt Catch, and its Plunger and Spring. Then drive out a second Roll Pin located at the lower front of the Receiver’s Magazine Well. The Magazine Well Insert can then be lifted out of the Lower Receiver. Two socket head screws hold the halves of the Magazine Well Insert - and its components - together. These can be removed for cleaning - use any quality firearms cleaning product.
  14. The “Split” Handguards on the Carbine may be disassembled at any point in your cleaning procedures as necessary. As the Slip Ring (often called Delta Ring) which holds the handguards in place has a strong spring (the Weld Spring), it can necessary to have a buddy help you. CAUTION: THE RIFLE SHOULD BE UNLOADED AND CLEARED. Place the Carbine’s Buttstock on the ground or a table, and press down on the Slip Ring with both hands. Have your buddy remove one Handguard, then the other. There are notches designed to align and hold the Handguards on the Handguard Cap (located just behind the Front Sight Base). There are also special tools designed to aid in Handguard removal / reinstallation. See these on Bushmaster’s website (http://www.bushmaster.com) or call 1-800-998-7928 for information/orders.
