So I need to take off the flash hider but I don't want to screw up my gun in any way, so I have a few questions:
1 is the mp7 flash hider 12mm CW? So this means rightly tight lefty loosely right?
2 I don't want to use boiling water unless I have to, but is there any other way to do it besides the hair dryer method?
3 I've heard mixed opinions on the hair dryer method. Some say its not hot enough and vice versa. Anyone have any success with the hair dryer?
Thank you for your time!

Looking down the barrel, righty tighty lefty losy.  A hair dryer is all you need.  Get a wrench that will fit the flat parts of the flash hider.  The hair dryer will take a few minutes but it will work just fine.  I removed mine with this method only a week or so ago.

Thank you so much! Now where can I get the adapter? And know of any good tracers for 80 or under? And anyone know what could be wrong? Full auto issue. Can only use one burst of full then it's like jammed, but its not. I have to go to semi shoot once then I can use it again. Any ideas? There was another topic like this but I don't think it got solved

Butane jet lighter was my weapon of choice for melting the glue.

Nope, I did take the front cover off of the frame because i couldnt get any flame to the threads. However, i wouldnt recomend this as the cover's latches are almost certain to bend or break when you take the cover off. I would recommend disassembling the gun and taking the plastic body off of the interior frame and the barrel. There is a good video on youtube on how to do this. Only do this if you are comfortable taking these things apart. If not, take the cover off, its a lot safer. You probably will break the latches on the cover, but you can just super glue it back on, I did, good as new.

Unless you melt the LockTite you'll just twist the whole barrel out of the gun trying to mount the barrel adapter.

I first removed the front receiver cover by carefully and patiently easing it off.  From reports here if you rush it you'll break it.

I used a heat gun -- a super hair dryer -- to melt the LockTite from the threads by heating the flash hider while at the same time keeping a wet rag stuffed around the barrel and receiver to keep the heat off portions of the gun I didn't want to melt.  Once the flash hider is off you can put the thread adapter in its place.

Ok so I'm still leaning towards the hair dryer, so could I just leave it on where the barrel and flash hider connect for about 20 minutes?

20 minutes with a hair dryer?  You don't need that much.  Maybe 5 minutes straight MAX.  I had it on for two and that didn't do it, then I left it for three or four and it was a little hard to get off but as long as you have a wrench it'll move.

Would 10 work then? I want it to come off easy so I don't damage the outer barrel.

You can do it as long as you want.  5 minutes was fine for me.

Need help again! Tried using hair dryer for 10 mins, didn't work, so added 10 more. I twisted and I think I may have made the outer barrel lose. When I try to wiggle the flash hider it wiggles! Is it loose because I melted the loctite or because of the barrel?

Does the outer barrel move?  Or just the flash hider?

I wiggle the flash hider and I believe it's the hider but I don't know how to tell for sure.

I'm pretty sure that you would be able to tell.  Did you remove the set/grub screw before attempting to remove the hider?

I got it used from a friend, and I checked for any screws and couldn't find any. I am almost positive it's the flashider lose because I test fired to see if the accuracy was any different and it was not, but could it still be the barrel?
Edit*
Believe I found the issue.
I looked at it as I wiggled it a bit, and saw the front black cover thing wiggle. When I hold it steady and try to wiggle the barrel nothing happens:)
Where is the screw so I know it's gone before I try this again?

Ok sorry if I wasn't clear but I meant the mp7, but I actually did try it with my cqr and it worked now! (For the cqr it worked but not the mp7)I just added 5 more minutes, but it still won't budge for the mp7.
