Default Problems with my stag, what did I mess up

I have a model 2t stag 5.56 and the first 200 hundred rounds cycled with no problem. I got home cleaned the rifle using m pro 7 and assembled. Since then I have only been able to shoot one round at a time. The case ejects fine and the next round cycles fine, but does not fire. When I clear the round it does have a light primer strike, and I can load the round with the light primer strike and it will fire. I have tried 5 different mags, all p mags and they function fine in others guns. This is happening with all 3 different types of ammo I have tried. I must have put something together wrong, as I have not added any accessories to the gun from the first time I shot it. I tried cleaning the buffer spring and re-cleaned everything on the gun again, but am wondering if there is something maybe one of you ran across or heard of that I am missing. Thanks for the help.

It sounds like a bolt or buffer issue. Did you take the bolt apart and clean it?
Definitely not mag related.

Did you put the firing pin all the way in before you put the retaining pin back in ? Pull the BCG and recheck it

Thanks for the reply, I did go ahead and clean the bolt, down to the extractor and buffer spring as well. Its weird because it does extract the spent round and cycles the next round but then I get a light primer strike, every time.

If you shake the bolt does the pin move freely? How's the end of the firing pin look?

That's what Im thinking is happening as well. I have watched a couple of vids on YouTube about cleaning and assembly but cant get one that shows the end of the firing pin and how much it should be able to move back and forth in the bcg when assembled.

Simple fix, pull the BCG out and remove the retaining pin. Pull the firing pin out and push the firing pin all the way in and reinsert the retaining pin . If you pull the BCG and you tap the back end on a hard surface the pin should not come out , I think its not all the way in , Very simple mistake that can ruin your day out shooting

Does the hammer fall when you pull the trigger or is it not getting reset? I'm having a similar issue but mine won't even strip the next round out of the magazine. I could be wrong but maybe your bolt isn't going far enough back to reset the hammer.

It does move freely and I cant see any chips or damage to the firing pin.
