New AR upper; hard to eject unspent rounds.

Update. After spending the week in Evansville, I finally got home and played. I lubed the bolt and charging handle VERY well, and also for giggles did the drill trick mentioned above with some oil on the brush.

Now it ejects nicely. Still slightly tight at first, but I think now it just needs a couple hundred rounds through it.

thanks guys.

I love a success story.

I thought you loved it when a plan came together. Or am I confusing you with somebody else?

Got a new inexpensive upper for plinking. Did a basic function test and it was good.

However I noticed when I was done, it was VERY difficult to eject that unspent round. (only 10 rounds sent downrange) to the point on the range I just sent that last round and packed it up because I was done anyway.

Playing with it at home, its still VERY hard to eject a live round. More lube? Need to scrub the chamber a bit? Just fire a bunch more to loosen it up?

Any suggestions? Its factory ammo, so it shouldnt be an out of spec ammo issue.

Glad you made progress with it cm. Can you be a name dropper on the upper and AMMO? All factory ammo isn't created equal.

Would suggest that the brass is size is causing your issue!

PMC ammo and Bear Creek Arsenal upper/BCG.

Oh, lightly oil in the barrel. With all the pressure behind the bullet, you don't want it pushing through an oil bath. Just run a patch to get out the excess.
