I tried to remove the hopper but still couldn't.
The next step was to take out the hopper with the adjustment ring by taking out the three screws. However one needs a very small screwdriver which is slanted so as not to hit the hopper. I did not have this tool. So I guess my only option is to take the hopper out with the adjustment ringby using the stepless knob as suggested by Joel.  I will try this tomorrow unless anybody has other suggestions.

I really don't know why it won't come out.  How much muscle have you put into it?  I'm just curious what's going on other than ALOT of debris.

I am quite puzzled myself. I tried pulling it out by myself and even asked my wife to hold the base down while I tried to pull but to no avail. It looks like it's stuck like when a lid is vacuum stuck to a jar. With a jar though you can pry it with a knife to take out the vacuum.

LOL! Well, one thing I do know is that it's not vacuum packed :)

Just to clarify, you have tried moving the hopper in various movements correct?  Back and forth, rotating, gentle shaking, etc.

Yes I tried moving the hopper in all directions.  What I notice is that it wiggles a bit but it wiggles together with the adjustment ring so it really looks like the hopper base is wedged.  Unless its really supposed to be together (hopper base and adjustment ring).

Did you look down inside the throat of the hopper to make sure there isn't a retaining screw that comes in from the side of the throat under the adjuster ring you have missed? I sold my M4 a year ago but I don't recall removing the hopper being any big deal. Opening up the burr area for cleaning was a pain so I posted this mod which you might consider once you solve your current problem.

Yes there are no other screws on the side of the throat although there are 3 holes there.  I don't know but the person I bought it from hasn't changed the burrs for 2 years so I'm not sure if he did take out the hopper before.

Thank you for the link you sent regarding opening up the burr area for cleaning!

Finally I was able to remove the hopper but not without difficulty. This is what I did.

I swung out the adjustment assembly as per JV so that I could turn the hopper with the upper burr assembly clockwise and remove it. With the hopper and upper burr assembly removed I still could not remove the hopper. I then decided to put the hopper/upper burr assembly in the freezer for about 10 minutes thinking that with cold, the hopper base might contract and I could eventually take it out.
Actually I forgot all about it until my son asked where the hopper was. Casually I told him I left it in the freezer and as I got the hopper/ upper burr assembly and showed it to him, I tried to
pull the hopper and lo and behold- it pulled out quite easily to my surprise!  So there.
So thank you everyone who helped!  I am now a happy camper!

LOL!  Ha, good to hear.  So was it all gummed up with debris or was it just a tight fit?

There wasn't really much debris on the sides so I think it was just all stuck up!  Funny how it was really stuck and couldn't even move it an inch and with just a simple freezing, how it came out without much pulling!
