I have a 14.5 inch m4 barrel upper with an AK break. Standard lower and stock.
I had the conversion done by bushmaster. I shot the gun today, and it would not cycle
every shot. I used several different mags and 2 types of ammo both .223 and 5.56

Any ideas as to why it is not cycling?

What conversion?

I think he got the ares/bushmaster kit.

It is Ares/ Bushmaster kit. I called Bushmaster, and they told me it
sounded like a lube problem. I just cleaned it up and lubed it. I will
Test it on Monday.

Some help please Arfcom people.
Well anyway, I disassembled the 2 uppers with the conversions, and
I am giving it a good cleaning. I admit I missed a few spots. I have 't shot the
guns in a few years ( been busy shooting AKs and 22s).

PS: my dirty AKs would shoot, unlike the ARs.

The Ares system isn't "an AR", DI works.

I called Bushmaster for advise. I did what they told me to do.
I stripped the upper down, and cleaned it thoroughly. It worked with out
a hiccup. I used GI, Magpul and new thermold mags. I also used 5.556 and .223
ammo. No problems.
