Well that pretty much says it all, It won't budge. What do I do? Please don't tell me I need to take it to a gunsmith, I just got it last night and havn't ever even fired it yet. There got to be a way I can fix this...

Any help would be great.

can you get the upper apart from the lower?

Is the round LIVE?

New barrel and shot wolf?

Yes, I did get the upper apart from the lower. I was able to get the bold out, I oiled it a little and put it back together. But now it is stuck again and I can't pull it back.

Is the round LIVE?

There is no ammunition in the gun

New barrel and shot wolf?

I have never fired this gun but it is slightly used.

Is there a round in the chamber? Did you drop the bolt/carrier into the upper without it being completely assembled?

I bet the bolt is gummed up in the carrier...and having a hard time rotating out of the locking lugs.

One way I deal with getting out a stuck BCG is remove the upper and lower. From the rear I take a rod that has a protected finish, think channel lock handles.

Then pry it out the back, you have a little more control and you're not beating the chit out of your BCG.

If you get it out, removed the bolt from the carrier and check to see there is not a lot of carbon buildup. Also make sure the gas key is tight while you're at it. Check the cam pin for wear and binding.

Yes, being a used  rifle you will want to do a detailed disassembly, inspection and cleaning before hitting the range.

I can get it apart and work it back and forth. It doesn't look like the carrier is getting hung up on anything but the bolt is definatly getting hung up on something. If I seperate the upper and lower I can work the bolt back with just a little pressure from a screwdriver and work it back and forth. However if I let it fly forward like you're supposed to chamber a round it gets stuck again and I can pull it out.

I received my new upper this past thursday from a good deal on EE.  He wrapped it in newspaper, so when I receieved the packages, the bolt and bolt carrier group was dry as bone.  I thought this was natural, due to it being my first rifle build.  So I popped the upper on the lower and every time I pulled the charging handle, the bolt would get stuck before it reached the half way point and the only way to get the bolt unstuck was to removed the rear takedown pin and roll the upper out.  

So I decided to clean and generously oil/lube the inside of the upper reciever.  Disassembled the bolt carrier group, cleaned and generously oiled.  Pute a little oil in the buffer tube.  After doing this, I am able to charge the gun easier.  Hope this helps.

There is a manual on how to oil and disassemble your gun properly, but I cant remeber where it is.  It was a .pdf  file from Bushmaster.  Great File.  I can email you the the file if you cannot find it.  

edit: bah a minute apart.  I least I know that you have the same problem as me.  Give my method a try.

This was sold to me as having a brand new bolt and carrier

With the bolt and carrier removed, try to move the bolt it self back and forth in the carrier. You can also slide the carrier alone into the upper receiver to see if the gas tube is binding. But I seriously suggest a detailed field strip, cleaning and lube.

If that’s the case then you most likely need LUBE!!!!

same here.  But i think you should lube it generously.  Tell me this, When the upper is not on the lower, can you slide the boat back easily?  I could do that to mine before I cleaned an oiled it.  Now, zero problems after the good lube.

If you take the upper alone and push the bult carrier group all the way in where the lugs are engaged how hard is it to get the bolt back out like that? Can you see any abnormal wear on the bolt, or carrier, or charging handle?

[#13]
it should be easy to pull back.  I do not know what you mean by abnormal wear?  There is gonna be some scratch makrs due to the sliding mechanism.

If it is new you should not have any scratch marks on it realy. You would be able to tell abnormal wear easily, even if the parts were old you could tell this. FWIW I dont have any scratch mak=rks on my bolts or carriers. I have some wear marks but they are all even wearing and took along time to show up. If there is an area that the BCG is hangign up at there should be some signs, IE unever or abnormal wear marks.

And it should be easy but if his is then it rules out possibilities of where it is hanging up at.

I stipped it and lubed it with CLP the bolt is just not rotating freely inside the bolt carrier. That's were it is getting stuck. maybe if I lube it good and put a couple of hundred rounds through it it will wear in, or should it be rotating smoothly before going to the range?

I would put it together and work the shit out of it. If it is still not going freely then there is a problem somewhere.

Is the carrier shrouded or unshrouded?

It looks like after stripping and lubing the bolt/bc, it is working, it is pretty smooth now.

Thanks a ton for the help everyone, you guys were great, I really appreicate it.

One of the more amusing demonstrations I have ever seen was a pissed-off instructor shouting at a guy (Note: Not Me!) about why doesn't he use enough lube on his rifle.  The guy, convinced of his own wisdom, starts spouting off about 'minimal lube, super lubricant, surface something, excess lubricant causes drag...' at which point the instructor asks for the guys rifle for a demonstration.

He then took the top off a big spray bottle of CLP, and POURED about 10 ounces out of the thing over the rifle (with the bolt closed).  He just plain drowned the thing.  The guy who owned the rifle was apoplectic, I thought he would hyperventilate.

The instructor then loaded up and rattled off 30 rounds downrange.  CLP was flying everywhere and the smell was intense.  He then handed the rifle back to the guy and said something to the effect of 'I've never seen a rifle not run with too much lube, only too little'

Very cool.
