I am new here today. I recently put my AR together. The picture below shows what is happening. It fires one round and the spent casing does not eject. I am not sure if the extractor is ripping the lip of the casing off or pushing forward upon entry. I was able to load this casing by hand and it didn't push it over, so I am thinking that it is pulling it off. When I use a cleaning rod to clear the casing, it just barely takes a little tap to get it out. What could cause this. Is the chamber just a hair too small? Could it be the extractor? Other possibilities?? I need help. I really want to take this gun to the range and have some fun. Any and all suggestions and helpful answers are greatly appreciated.

Would help to see the sides of the spent case to make sure that you cleaned the barrel/chamber correctly with brushes/chamber brush to remove the storage grease and debries in the chamber before firing the rifle, but if you are sure that you cleaned such out of the chamber and lubed the upper bearing areas correctly, then you are either under sprung/wrong buffer in play, or the barrel gas port is too large, and getting to much gas pressure back to the gas action to cause over function.
Simply, we need more details on the rifle, including barrel OD at gas port, barrel length and gas port size to check if the gas port is correctly sized to begin with, then the lower receiver butt stock and receiver extension parts to see if you have the wrong recoil spring and buffer in play as well. |
