Thread: AR15 shell cases not extracting

Hi
I was shooting some tin w my NEA AR15 last weekend.

After about ten shots the cases weren't extracting. I'd need to manually work the extract lever (correct lingo?) to extract. The cases would feel quite hard to pull out.

It would cycle ok for a couple more shots then jam up again

Am I doing something wrong??

I'm new to using my AR, be gentle please!

Thanks

Si
