Thank you for the response
Stranger things have happened in the AR platform.
If this appears to be the problem, It sounds like you need to size the brass smaller. (Factory ammo for
autos is small base sized.) with more head space and a smaller body for ease of chambering in a tight
chamber. If your dies are adjuster all the way down you can grind .002 to .003 thousandths off the bottom of the sizing die or buy a small base sizing die. Hornadys New dimension dies will also do this.
At one time all AR15/M16s had a forward assist button to help seat the bolt in battery, if yours doesn't
you will have to size the brass a little more.
Hope this helps.
