Flash hider removal trick???

You can use a strap wrench. Put the strap around the barrel and a wrench on flash hider. If not get local smith to take off for you or buy vise and vise blocks.
 
Put a wrench on it and give the wrench a few sharp whacks with a big wood hammer handle. Done a bunch that way, before having the "right" stuff, never had one not come off.
 
I am absolutely in awe.....

I put some leather on the gas block and vise-gripped it down, wrench on the flash guard and gave it all I had.... I am not a little guy...

I am going to be AMAZED if my gunsmith can get this off. vise or not my bet is the upper bends/breaks before this thing twists off.

EDIT: I also tried the hammer tap.... no dice

Holy crap is your gas block pinned or on with set screws? Lucky it's still in one piece and not twisted off or ruined.
 
I'm just gonna stop messing with it before I do break something....

I'll skip class tomorrow and go see if my gunsmith can work some magic!
 
If you have a table saw, I took some 1-1/2 inch square stock, cut off (2) 4 inch pieces. Centered in each piece I cut a VEE about 2/3 the way through the block. I took some 3/4 or 1 inch heavy fiber lined rubber tubing and slit it down the side. Put the rubber tube on the barrel a few inches below the flash hider, place the wood blocks on both sides and hold it in place with a rubber band. Place in your vise. Don't over tighten. You will notice that the barrel is contacted in all four quadrants and on opposing sides. Use your wrench on the flash hider. If it starts to turn in the vise, tighten it a little. I'm thinking it should come off without much effort. I bought the same upper and it came off no problem.
Good luck.

I dont think they are left handed threads and that really is a pretty clever idea but I dont have any of the things needed...
 
Heat works. You can use a hair dryer and really let it get the temp up on the FH.

But if you don't have a vice block, a vice, and a strap wrench (unless slotted) I would let somebody else do it.

My 2 cents.
 
I had a similar problem with my FAL until I searched around on the net and found out in many cases they were put on using a thread locker such as loc-tite. I heated it up for a few seconds with a butane torch and it spun right off.
Not saying this is the case for your AR, but you might check with the manufacturer to make sure, just in case it's something that simple.

Ooops. Looks like I am too late.
