I just received my 24" bull barreled flat top upper receiver from model ! Sales and I am having a problem with a failure to feed from the "last bolt hold open" posistion. Does anyone have any ideas? It doesn't matter the name or size of the mag, either.Thanks.

Can you get a "go" gauge to check for sufficient headspace? Are you talking about when you've put in a fresh mag? With the charging handle forward? How far does it get? Properly lubed? Does the buffer spring spec out OK? Did the bolt & carrier come with the upper? Does it happen every time for this condition? Does the upper close to the lower nice and tight?
