| So took my newly assembled AR to the range and I insert the magazine (Magpul) and the first round fires. The gun ejects the spent casing and loads a new round, but when I go to pull the trigger the gun does not fire. Any thoughts or suggestions? Thanks. |

If the hammer has gone forward but not caused the chambered round to fire,,,check:
- Hammer spring installed backwards. Reinstall the hammer spring correctly. -Disconnector not catching, allows the hammer to follow the bolt carrier forward. Check for propper disco spring install and free movement of the disco. Do a function check to ensure parts are working properly. -Debris like a popped/loose primer inside the trigger group that prevents normal movement of the parts. Check for junk in the receiver, then do a function check to ensure parts are working properly. The hammer spring is the most common, but the other stuff may happen.
