I just installed a Bushmaster .22lr upper on my AR.  However, the buffer tube for the rimfire upper will not fit inside the stock for some reason, so I left it out.  I closed up the weapon, but now the bolt is pulled to the rear, with no buffer spring inside.  It won't move forward, no matter what I do.  It isn't stuck on the buffer detent pin, and I can't figure it out.  

Any help would be appreciated.  I figure it might help to pull off the stock, but I don't know how.  Thanks.

Won't it come forward it you strike the flash hider on a concrete surface?

Uh, I am going to try that as a last resort.

OK, I unscrewed the stock and pulled it out that way.

Concret surface? how about wood?
