How to remove flash suppressor from dpms 223 sportical?

There’s no definitive answer, as each rifle is unique. However, here’s one approach that might work on your DPMS 223 Sportical:

1. Make sure the firearm is unloaded and pointed in a safe direction.
2. Remove the barrel from the upper receiver. This can usually be done by loosening two screws located on either side of the barrel (near the gas block).
3. Look inside the barrel and you should see a small nut or screw at the end (this is the flash suppressor).
4. Use a wrench or pliers to loosen and remove the flash suppressor.
5. Replace with a new flash suppressor, if desired, and tighten securely using a wrench or pliers.
6. Reattach the barrel to the upper receiver and tighten the screws securely.
7. Again, make sure the firearm is unloaded and pointed in a safe direction before proceeding.
