How does one go about removing a factory installed hider? I have a Troy 10.5" upper I need to put my AAC hider onto.
Do I need a vice and clamp or some other special tool or is it just a matter of brute force?

Depends if the muzzle device is permanent (pinned, welded, silver soldered, etc), or just screwed on. Might have a chemical thread locker like rocksett or loc-tite as well.
To avoid possibly twisting your receiver, I'd recommend clamping the barrel at the front sight base in a vise between a couple pieces of wood to keep the jaws from marring the metal.
Then just screw off if it's non-permanent. Might have to hit the muzzle device with a torch to break down the thread locker if any was used, but try it cold, first.
If it's permanent, you'll likely need to take it to a smith unless you know the permanent attachment method and how to get it off.
Wrap the barrel in copper wire and put it in a vice with wood blocks and have at it.
I'd contact Troy and ask then what they use. Pins are mechanical and have to be drilled and or punched out. Some are taper and only can be removed one way. Rockset is NOT chemical, it can be softened in hot water or shock fractured to remove the device. Locktite is a corrosion process and may be hand tool removable, heat removable and some are actually permanent.
This I did not know. So the locktite creates corrosion to 'fuse' (I don't have a better word) the metal together?Quote:

Anodization, Zinc, Black Oxide all passivate the metal reducing the bond strength of Locktite. Corrosion also results in a slight increase in volume and the formed oxides overlap to lock the connection.Quote:

BlackMax FTW lol.........Quote:

Make sure to use some Rockset on your new muzzle device. Don't want it coming unscrewed with the can on there or when removing the can.
I'd be happy to help but you'd have to come way the hell up north. Lol.
If it's pinned[pick-me]
I would be surprised if it were pinned. I just wouldn't see a need or reason for it to be done on a 10.5" barrel.Quote:

Cursory inspection didn't reveal a pin but I only took a quick look at it the other day. Sunday I'll dig deeper, if I need to make a call to Bert Monday we will have our answer.
I have a SawZall.......
ps you're welcome to come to Idaho Springs and use my bev block. I too doubt a 10.5 is pinned...unless it has a 5.5" muzzle device.[ROFL2]
