AR not going into battery with 1st round

[timcar86]

Changed the stock on my AR to a fixed length Magpul MOE stock. It required a rifle length receiver extension tube so I had to get one of those too. After I've changed that out I'm having issues with the bolt stripping the 1st round off the top of a full magazine. It won't go fully into battery. After the first round it cycles fine. Do I need to add a spacer or something? Thanks in advance.

Did you put in a rifle buffer?

Does it fail if you lock bolt back, insert mag, and drop bolt with release, or just when you use charging handle?

After a second look I have discovered that was my missing piece. I have the carbine buffer in and not the full length rifle buffer. Thanks for the response.

Sounds like Mr. Trout probably nailed it right off.

You also need to use a rifle length recoil spring. A carbine length recoil spring will not have enough force to reliably run.
