I think this has been discussed, but I cannot master the search engine well enough to find it.

I want to replace the factory M2 flash hider on my 556 OBR with a SOCOM muzzle brake.  Is there a procedure for removing the flash hider?  Something like heat or chemical to loosen whatever kind fof thread locker was used by LaRue?

TIA,

Tommy

I'm 99.99% sure no thread locker was used on the two I've removed.  I just twisted them loose with an armorer's wrench

Or if you do not have an armorers wrench an adjustable wrench will work just fine.

Yep, I wrap the teeth of a crescent wrench with tape and just remove.  This way you don't scratch the finish on the nut.

I just removed mine no problem with a 3/4 open end wrench I believe (I would go double check but it is in my closet next to our nursery and our girls are asleep). I had my machinist "thin" out an extra wrench I had around and it fits nicely now.

Thanks for all the replies!  Just to confirm, what do you use to hold the barrel while removing/replacing the muzzle device?  Do you lock down the receiver and go to it?  Or chuck the barrel up in a set of purpose-built jaws in a vice?  Remove the handguard so you can clamp the barrel?  Other?

TIA,

Tommy

1st one I used a vise block,and for the second, I had my buddy hold the receiver while I torqued the wrench.

I have a 30 year old Snap On 19mm open end wrench that I use.

It would be cheaper to pay a smith to remove it for you.
