AR15 won't cycle (Update)

Also make sure gas rings are staggared on your bolt.

This makes no difference at all.  The slots are compressed whent he bolt is seated in the bolt carrier.

I will disagree but that can be a different thread.

Since your gun is brand new I would take it back rather than mess around with trying to fix what may or may not be wrong with it. Let us know what the outcome is.

I know I'm a ways, but I would be happy to gauge it and give it a once over.

I'll test it tomorrow if you want.  I've tested it, and I've also heard straight from Ken Elmore that it makes no difference.

I agree 110% with this.  Your gun has some issues with machining and/or parts.  I am assuming you are not overly familiar with these rifles.  Given that plus it's brand new I would take it back to the dealer and have them make it right.

Just my two cents, but I'd find an armorer who is close to you, let him run it a bit, and see what he/she thinks. It's difficult to diagnose a problem with a firearm via a forum post and with you being new to this system it could be something really easy to correct. This would also rule out that you are inducing the problem, which if that is the case getting another rifle won't fix.

I've read some of kens stuff. But in 18 years of running, building, fixing, cleaning and teaching AR platform's I have always been religious about them dam gas rings. It's something engrained in me. So, I always recommend people check them. I have on isolated occsssions seen them be the cause of function problems. Sorry, old habits are hard to break.

First, Make sure and look in the chamber closely just to make sure something isn't in there.  If the headspace is off you can have a round that separates in the chamber and then the next round will feed right into what is left of the separated case that is left in the chamber. 

From what you are describing, I would imagine it is a headspace issue...

We all used to worry about them but it has turned into kind of a wives tale.

Just wanted to give an update. I took the gun back to the shop and they tested it and found out that the BCG was not lining up in the feed ramp properly so they filed it down a bit and did some test shots and the gun performed well. Thanks to everyone for all of your help and advice.

Thanks for the update.

Makes you wonder about the machining process, eh?

[300rum]

When you have a chance, take a pic of where they filed it down.

I'm sure they just filed down a locking lug or two. No biggy..
