The muzzle device (AAC) three pronged flash hider is stuck on the barrel (AAC) as you guys know this is time sensitive because I don't have that long before I return to kuwait.

When I say stuck I mean some Damned gorilla installed it with a 10 foot cheater bar while he was hoped up on Meth or some ****. This is after the AHOLE slathered enough rockset for 3 barrels on it. This was all done at the factory. All of this was done by AAC.

I Took the thing to a local Boutique gun shop that specializes in high end AR's and have a competent gunsmith in thier employ. This guy vised in and used the AAC three pronged removal tool and failed as well. Given the time sensitive nature of my situation what would you gentleman suggest I do. I am located in Jacksonville.

the point of this excersize is to mount my Saker on it and shoot supressed. Please help.

Isn't the Rocksett water soluble? Maybe you can try soaking it overnight and have another go at it with the vise/tool.

I have only heard 2 solutions to this
1. soak it in water overnight like suggested ^ This will loosen the rocksett
2. If you cannot get it off I know AAC will take it off for you using magical pixes or something

So try 1. if not then you probably will have to do 2.

I am going to try this. Upon further research folks are suggesting boiling water as well. If it works I'm going to shoot it when I get it off. Because F this thing and the horse it rode in on.

I took mine off by soaking in water overnight, then heating it up with a heat gun to the point of turning red. You will need a vice to hold it and a lot of elbow grease. Rocksett aint no joke.

Tried heat it up with a torch? I had a flash hider stuck on a friend's gun. I heated it up with a small blow torch and it broke free pretty easy.

I stuck it in the Fire last night. As tempted as I was to throw the whole thing in I resisted and just stuck the flash hider in. No joy. It was cookin too. I am thinking the boiling water thing sounds pretty scientific and I am liking it to be the solution. I will report back tonight after I either fail or succeed.

Propane torch? Cook off the sealant. Only issue is that I would not let it turn red. Not sure what the heat treat of the steel is that you might ruin if you get it too hot.

Are you worried about saving the flash hider? If you are really desperate, get a dremel and an abrasive cutoff wheel and put a slice in it going lengthwise. Really careful so you don't slice into the barrel, but if you go deep enough to just barely get to the barrel threads, you ought to be able to get a screwdriver in the slit you cut and bust the thing open.

This /\ /\ /\ I would cut the slits in line with the 3 prongs. Put the barrel in a vise and use a big screw driver on the FH prongs. I have done it a few times to remove devices that were pinned and the thing just splits. Go slow with the dremel and even if you do nick the threads, just chase the threads and rockset the new brake/flash hider on. Good luck

Well guys AAC really F'd this one up. Seriously. I'm a more than a little pissed off. I tried the boiling method. I heat that B*tch up until it was glowing red cherry hot. It wouldn't budge. What the F'ing F AAC!!!!!! I know without a shadow of a doubt these guys are going to take three weeks to get this thing back to me. Looks like I won't be shooting 300blk while I'm home. What a major pain in the ass and disappointment this is. I can't express how let down I am. There is no reason for it to be this way. If they want there GD flash hider permanently attached they should just weld the GD thing and call it a day.

Customer Beware!!!! If you want an AAC upper best let them know you don't want their flash hider and to take it off. Because if not you are stuck with it.

As far as dremeling it. I am very tempted but I don't know how thick the stupid thing is and I am afraid I would get into the threads.

This whole thing sucks.

Talking off the cuff here but does penetrating oil do anything to the thread locker? How about you find a place that has a barrel. buy the barrel and have the barrel installed. then return the old barrel with the stuck on flash hider as defective?

I may go that route. I am calling AAC in the morning. We will see what they say. I hope their reputation doesn't show its ugly head in the morning.

Kam, that really s*ks. I am having the same issue with the FH on the SCAR17 13" barrel. Tempted to get a 36" pipe wrench on the bastard. Either it is going to come off or I am going to break the barrel. Why the h*ll they have to put them on so tightly is beyond comprehension. Especially for a battle rifle that an operator may need to make some field modifications.

Damn Kam, it's like the world is sh!tt!ng on you this week. I really don't know what to add as all of the methods of removal have been mentioned.
Yeah but there is a smattering of good in there too. I'm trying to keep a positive outlook.
