Please read and understand these safety guidelines before attempting to handle or use your firearm. Take a firearms safety course to ensure firearm safety and knowledge. Local, state and federal Law Enforcement and Fish and Game departments provide excellent courses on firearm safety.

  • Always handle your firearm as if it were loaded.
  • Never point your rifle at anything you do not intend to shoot.
  • Do not handle firearms while impaired under the influence of alcohol or drugs. Never leave a loaded firearm unattended.
  • Be sure firearm is unloaded and bolt is open before handing it to someone.
  • Before starting an inspection, be sure to clear the rifle. Do not pull the trigger until the rifle has been cleared. Inspect the chamber to ensure that it is empty, and no ammunition is in position to be chambered.
  • Do not keep live ammunition near work area.
  • Only use ammunition designed for your firearm. Failure to use the proper caliber ammunition will cause damage to your firearm and may result in injury or death.
  • Only use quality commercial ammunition that is in good condition. Using corrosive, lacquer coated, damaged, hand loaded, steel or aluminum cased ammunition will void the warranty and if used, may cause personal injury or death. Since reloading practices are beyond our control, we disclaim all liability for damage or injury that may result.
  • When shooting your firearm, know your target and beyond.
  • Use eye and ear protection when shooting your firearm.
  • Never alter or modify your firearm. Do not disassemble your firearm beyond this manual.
  • Only a qualified gunsmith should service, repair or modify your firearm in any way.
  • Obey all local, state and federal laws in regards of discharging, handling, storage, security and transportation of your firearms.
  • Cleaning, discharging, handling of your firearm and ammunition may result in exposure to toxic and hazardous substances. Wash hands thoroughly after exposure. Read all warnings on ammunition, cleaning and lubrication products.
  • To avoid injury to your eyes, use care when removing and installing spring-loaded parts, cleaning, lubricating and handling of your firearm.
  • Never allow another person(s) to handle, shoot, clean and lubricate or use your firearm if they do not understand or have not read the safety guidelines of this manual.
  • Do not rely on the firearm’s safety. It is only to be used as a supplement to safe firearm handling procedures.
  • Do not touch the trigger or trigger guard unless you are ready to fire.
  • The bolt must be completely closed in full battery when firing your weapon. Failure to have the bolt closed will cause a catastrophic failure that will result in injury or death.
  • DO NOT interchange any parts, especially bolt assemblies from one OMEN rifle/carbine to another. Doing so may result in injury or death.
  • Bolt cam pin must be installed, or rifle/carbine will blow up while firing. If the bolt cam pin is not installed, injury or death may result.

If there is water or an obstruction in the barrel, including the chamber and barrel extension, do not fire. The gun may explode and cause damage to firearm and personal injury or death.

Do not drop your firearm, it may discharge. A dropped firearm must be inspected by a qualified gunsmith to ensure firearm is undamaged and safe to operate.

There is no safety substitute for common sense. You, the owner, are the most important safety device when it comes to the use of your NEMO Arms, Inc. firearm. The safe use of your firearm is your personal responsibility. Failure to follow these basic guidelines may result in property damage, injury or death.

Clean and inspect your firearm regularly. Failure to clean and inspect your firearm regularly will void your warranty, and if discharged may cause property damage, injury or death.

If you notice a difference in sound or recoil from your firearm, stop firing. There may be a bullet lodged in the barrel, ammunition malfunction, overheated barrel or firearm, or could indicate any number of problems. Point firearm in safe direction. Wait 15 minutes for rifle to cool. After 15 minutes, unload rifle and clear chamber. Check bore for unburned gunpowder, brass or lodged bullet. Bullet, brass, primer, foreign object and unburned gunpowder must be removed before re-chambering another round and firing. Failure to clear foreign objects and re-chambering another round on top of any debris, may cause a catastrophic failure causing damage to your firearm, injury or death. Take firearm to a qualified gunsmith for assistance of bullet stuck in barrel or debris that cannot be removed for removal and inspection.

Extended, continuous, or rapid firing will raise barrel to unsafe temperature. At this temperature, any live ammunition in chamber may detonate without pulling trigger. The heat from the barrel alone may cause ammunition to detonate. Allow adequate time for firearm to cool to prevent an overheated barrel. Allow barrel to cool to ambient air temperature.

Do not exceed 10-12 rounds per minute to prevent an overheated barrel, reduced barrel life, and/or voiding your warranty.

You must check your ammunition prior to using your OMEN. It must be within SAAMI specifications for size and pressure.

Blown and pierced primers will damage bolt and firing pin. A pierced primer will cause firing pin to continue to pierce primers and may cause a catastrophic failure to your rifle and serious injury or death. Your firing pin must be changed out immediately upon piercing primers.

The firing pin spring, see picture on page 10, must be installed. Failure to install the firing pin spring after cleaning may cause accidental discharge or out of battery discharge, resulting in injury or death.
