2.0 PRECAUTIONS IMPORTANT: THIS DANIEL DEFENSE PRODUCT IS POTENTIALLY LETHAL! IT IS CLASSIFIED AS A FIREARM OR DANGEROUS WEAPON BY THE BUREAU OF ALCOHOL, TOBACCO, FIREARMS AND EXPLOSIVES. IMPORTANT: READ AND UNDERSTAND THE ENTIRE USER MANUAL BEFORE REMOVING THE FIREARM FROM ITS PACKAGE. YOUR SAFETY AND THE SAFETY OF OTHERS REQUIRES YOU TO FOLLOW THE BASIC INSTRUCTION ON THE PROPER HANDLING AND FUNCTIONING OF THIS DANIEL DEFENSE FIREARM.
3.0 SAFETY INSTRUCTIONS Regardless of your experience level, we urge you to read this entire instruction manual carefully. BASIC RULES FOR FIREARM SAFETY 1. ALWAYS treat every firearm as if it were loaded. a. Never take anyone else’s word that a firearm is unloaded. b. Always visually inspect the chamber (and magazine, if equipped) yourself to ensure that the firearm is completely unloaded even if you just witnessed someone else perform this safety check. c.
3.1 CAUTIONS EQUIPMENT CAUTIONS 1. ALWAYS BE SURE THE CHAMBER, BORE, SUPPRESSOR (IF EQUIPPED), AND ACTION ARE CLEAN AND CLEAR OF OBSTRUCTIONS. Keep your firearm clean and well lubricated to ensure it will function correctly and safely. 2. ALWAYS USE HIGH-QUALITY, COMMERCIALLY MANUFACTURED AMMUNITION THAT IS CLEAN, DRY, IN GOOD CONDITION, AND OF THE APPROPRIATE CALIBER FOR YOUR FIREARM. Firearm and ammunition manufacturers design their products within exacting engineering safety limits.
7. NEVER fire a firearm if you suspect water is in the barrel or gas tube. a. If your firearm is exposed to heavy rain, fog, or other sources of water, open the bolt and allow water to drain before firing. b. Be sure to clean and lubricate a wet firearm as soon as possible. 8. NEVER shoot your firearm near any flammable or explosive materials. a. Understand that flames may exit from your muzzle or ejection port. 9. NEVER fool around or act carelessly when handling or being around firearms. a.
SUPPRESSOR HANDLING CAUTIONS (DDM4ISR) 1. ALWAYS ENSURE THAT THE MONOLITHIC BAFFLE IS SECURE IN THE SUPPRESSOR ASSEMBLY BEFORE SHOOTING. a. Upon cleaning or performing maintenance on the suppressor assembly, always ensure that the baffle is securely tightened in place before firing (See Section 5.6 DDM4ISR Sound Suppressor Maintenance for more details). b. Serious injury may result from improper baffle installation. 2. NEVER DISCHARGE THE FIREARM WITH ANY LIQUID INSIDE OF THE SUPPRESSOR ASSEMBLY. a.
of the trigger, blocking the sear surface of the trigger and preventing the hammer from being released. When set to “SEMI,” the firearm will fire a single shot each time the trigger is squeezed without manually reloading. SAFE (DDM4) SEMI (DDM4) SAFE (DD5) SEMI (DD5) Daniel Defense® Full Auto Firearm Some law enforcement and military platforms feature a three-position safety selector, “SAFE,” “SEMI,” and a third position for fully automatic.
3.4 BOLT-LOCKING SAFETY FEATURES The firearm can fire only when the bolt is fully locked to the barrel extension. The bolt carrier is designed in such a way that the firing pin cannot come in contact with the primer of the cartridge when the bolt is not locked to the barrel extension.
3.8 GRIP-N-RIP™ AMBIDEXTROUS CHARGING HANDLE The DDM4 and DD5 platforms have been updated with an ambidextrous GRIP-N-RIP charging handle. Manipulating either handle moves only the latch giving an identical pull from both sides. The handle has been optimized for grip comfort without being overly bulky and getting in the way of obstacles or hazards. The GRIP-N-RIP charging handle will fit on any AR-15 pattern rifle, and the AR-10 version will fit on DPMS (Gen I) pattern rifles.
3.9 DD® ADJUSTABLE GAS BLOCK The DD Adjustable Gas Block is a two-position adjustable gas block designed with suppressors in mind. The gas block has a 90-degree throw between the unsuppressed and suppressed modes. A unique feature of the gas block is that it can be quickly adjusted through the side of the firearm’s handguard by rotating the throw lever with the DD supplied Allen wrench. SUPPRESSED UNSUPPRESSED 4.0 FUNCTION Daniel Defense firearms have semi-automatic actions.
the bolt pushes the next round of ammunition from the magazine and thrusts it into the chamber. Simultaneously, the extractor snaps into the groove of a cartridge case and the bolt locks into the barrel. The hammer is now held rearward by the disconnector until the trigger is released, causing the disconnector to rotate back, releasing the hammer.
4.1 AMMUNITION SELECTION WARNING: AMMUNITION OF THE CORRECT CALIBER MUST BE MATCHED WITH THE SAME CALIBER THAT THE FIREARM IS CHAMBERED IN. Daniel Defense recommends that you only use high-quality, commercially available ammunition that is clean, dry, in good condition and of the appropriate caliber for your firearm. The use of re-manufactured or hand-loaded ammunition is not recommended.
4.1.1 300 AAC BLACKOUT FIREARMS WARNING: NOT ALL AMMUNITION WILL PRODUCE THE SAME RESULTS. All Daniel Defense firearms chambered in 300 AAC BLACKOUT are designed to function with a variety of brands and types of factory-manufactured ammunition in the appropriate caliber. These platforms were designed to be shot suppressed and unsuppressed utilizing various types of supersonic and subsonic ammunitions. Many subsonic types of ammunition are designed to be fired in conjunction with a sound suppressor.
4.2 SIGHTS Depending on the particular platform, your firearm may have a mechanical sighting system, which allows you to adjust for variations in windage (horizontal adjustment) and elevation (vertical adjustment). The rear sight is adjustable for windage and the front sight is adjustable for elevation. The firearm has indexing numbers (T-Marks) on the mounting rails of the upper receiver and handguard to show locations for mounting accessories such as sights and optics.
1 METER = 1.09 Yards 1 INCH = 2.54 Centimeters 1 CENTIMETER = 0.39 Inches TRAJECTORY: the path followed by a projectile ZERO: the distance where the shooter’s line of sight and the bullet’s trajectory meet The purpose of sighting-in or “zeroing” your firearm is to confirm that your rounds strike the target where you expect them to. The operator of the firearm must decide at which distance to zero the firearm, taking into consideration how the firearm is likely to be used.
6. If your shot group is not centered on the target in WINDAGE, measure the distance from the center of the target. Adjust the REAR sight by rotating the windage wheel on the right side the number of clicks you calculate from the following chart: DATA ASSUMES: Rear sight @ T1 and Front Sight @ T-51 *Adjustment values will vary slightly based on sight radius* 7.
4.5 FORWARD ASSIST The forward assist allows you to help the bolt lock into the barrel, but it will only be useful on rare occasions when the bolt fails to lock automatically. When you must use the forward assist, it is usually time for you to clean your firearm, paying particular attention to the cleanliness of the chamber and bolt. Hunters may find the forward assist useful when trying to load their firearms more quietly in the field.
4.6.1 CHANGING BUTTPAD The buttstock equipped on Daniel Defense rifles can be customized with two different buttpads or run with no buttpad at all. To change or remove the buttpad, use the following steps: REMOVAL 1. Remove the two mounting screws from the buttpad with 1/8” hex wrench. 2. Remove the buttpad, bottom first, sliding down. ATTACHING BUTTPAD 1. Slide the buttpad up, top first, ensuring its tab fits behind the top of buttstock. 2.
4.6.2 DDM4 ® PISTOL DDM4 Pistols are equipped with a Daniel Defense Pistol Receiver Extension, a Third Party Pistol Stabilizing Brace and in some configurations a Folding Adapter. DO NOT modify your DDM4 Pistol from the original Daniel Defense factory configuration. Please consult with the applicable manufacturer of the Pistol Stabilizing Brace and Folding Adapter for information regarding proper use and safety. WARNING: DDM4 PISTOLS ARE NOT DESIGNED TO BE FIRED FROM THE SHOULDER.
WARNING: READ AND UNDERSTAND ALL SAFETY INSTRUCTIONS (SECTION 3). 1. Use only ammunition recommended in this instruction manual as suitable for your firearm and application. The caliber your firearm is chambered in will be engraved on the barrel near the chamber. 2. Examine the ammunition, particularly on and around the primer. Look for dents, scratches, and other signs of damage. Do not load damaged ammunition. 3.
WARNING: THE BOLT CARRIER GROUP BEING LATCHED OPEN IS NOT A SAFE CONDITION WHEN A LOADED MAGAZINE IS INSTALLED. 3. Return charging handle fully forward until it locks and remove finger from bolt catch. 4. Set safety selector lever (located on both sides of the lower receiver) to “SAFE”; this will lock the trigger. 5. With bullet points facing forward, insert the loaded magazine into the magazine well and push upward until it stops and is locked by the magazine catch.
FIRE CONDITION AND IS EXTREMELY DANGEROUS. FIREARMS CAN EASILY BE ACCIDENTALLY DISCHARGED, CAUSING INJURY, DEATH, OR DAMAGE TO PROPERTY. WARNING: THIS FIREARM MAY DISCHARGE ACCIDENTALLY WHEN A ROUND IS FED INTO THE CHAMBER IF IT IS DROPPED OR RECEIVES A BLOW TO THE MUZZLE OR FRONT OF THE FIREARM (THIS CAN OCCUR REGARDLESS OF THE POSITION OF THE HAMMER OR ANY OF THE VARIOUS SAFETY DEVICES).
6. Remove remaining live rounds by sliding them forward out of the magazine. 7. Collect live ammunition for safe storage and spent cartridge cases for disposal. 4.9 FIRING Before firing, practice your stance, sight picture, and breathing for steady aim with your firearm UNLOADED. Practice firing on a range before using your firearm for any other type of shooting. WARNING: ALWAYS WEAR AND ENCOURAGE OTHERS TO WEAR EAR PROTECTION WHEN SHOOTING, ESPECIALLY ON A RANGE.
WARNING: THIS IS A SEMI-AUTOMATIC FIREARM AND IS IMMEDIATELY LOADED AND READY TO FIRE AFTER EACH SHOT UNTIL THE MAGAZINE IS EMPTY. TO UNLOAD THE FIREARM, THE MAGAZINE MUST BE REMOVED, AND THE BOLT CARRIER GROUP MUST BE PULLED TO THE REAR WITH THE CHARGING HANDLE TO EXTRACT ANY REMAINING ROUND FROM THE CHAMBER. WARNING: THIS FIREARM CAN ALSO BE FIRED WITHOUT A MAGAZINE IN PLACE. 6. Release trigger, remove finger from trigger, and set selector lever to “SAFE.
WARNING: IF YOU LOAD YOUR FIREARM BUT DO NOT FIRE IT, KEEP THE SAFETY SELECTOR LEVER SET TO “SAFE” UNTIL YOU ARE READY TO FIRE. WARNING: NEVER LEAVE YOUR FIREARM COCKED AND READY TO FIRE WITHOUT SELECTOR LEVER SET TO “SAFE,” AS THIS IS THE FIRE CONDITION AND IS EXTREMELY DANGEROUS. YOUR FIREARM CAN EASILY BE ACCIDENTALLY DISCHARGED, CAUSING INJURY, DEATH, OR DAMAGE TO PROPERTY. 5.0 MAINTENANCE Your Daniel Defense firearm will perform better, last longer and remain safer when it is properly maintained.
7. Push in the firing pin retaining pin from right to left of the bolt carrier group and remove the pin by pulling it out to the left. 8. Tilt the bolt face up and remove the firing pin (and firing pin return spring – for DD5 only). 9. Push the bolt in toward the carrier until bolt rotates and comes to a stop, then turn the bolt cam pin through 90° (not necessary on DD5). 10. Remove the cam pin by lifting it out and away from the bolt and bolt carrier. 11.
PERIODICALLY, when your firearm has not been fired, we suggest you clean it when necessary and at least once or twice a year in a temperate climate, or as often as once a week in a tropical climate. IF YOU CARRY A LOADED FIREARM, UNLOAD it and clean when necessary and at least once a month. If you get your firearm wet, clean it as soon as possible. 5.
WARNING: CLEANING FIREARMS, DISCHARGING FIREARMS IN POORLY VENTILATED AREAS, OR HANDLING AMMUNITION MAY RESULT IN EXPOSURE TO LEAD AND OTHER HARMFUL SUBSTANCES WHICH ARE KNOWN TO THE STATE OF CALIFORNIA TO CAUSE BIRTH DEFECTS, REPRODUCTIVE HARM, AND OTHER SERIOUS PHYSICAL INJURY. HAVE ADEQUATE VENTILATION AT ALL TIMES. BE SURE TO ALWAYS WASH HANDS THOROUGHLY AFTER POSSIBLE EXPOSURE. 1. Strip for cleaning as previously described.
9. Lightly dampen a flannel patch with gun oil and pass it once through the barrel, leaving a thin film of oil on the inside surface. Leave this film of oil on the surface if firearm is to be stored. If it is not being stored, or if it is being removed from storage for use, pass the dry patch through the barrel and chamber to remove as much oil as possible. 10. Check that flannel or brush bristles have not become lodged in any part of firearm, then lightly lubricate (See Section 5.4). 11.

Store your firearm and ammunition securely locked in separate locations out of the reach and sight of children. (Children are naturally curious and do not always believe or understand the real danger and responsibilities of firearms.) NOTE: Do not store your firearm in an airtight container, and do not seal or attempt to seal the barrel to exclude dust, as an internal steel surface is more likely to corrode. 5.
