Removing stuck flash hider

[BPTactical]

Try the Kroil first. Don't water soak it unless you are relatively sure Rocksett was used, typically it is only used on suppressor QD's. A hair dryer will not produce enough heat, you need a propane torch at the least.

Or a heat gun, industrial heat guns put out plenty of Heat, hot enough to melt mechanical solder, without the flames.

One of my favorite techniques for really stubborn things like that is to just cut them and split them, assuming you don't mind destroying the flash hider. Bert will probably scold me for using the "D" word, but take a dremel tool with a cut-off wheel and split that sucker lengthwise in two places. Be careful not to cut into the barrel. Usually, I will stop just short of cutting completely through the nut (or flash hider in this case) and then split it off in two pieces with a chisel.

If you're not good with tools or you don't have a ton of patience, I would definitely recommend seeking some professional help.

+1 for Kroil. I have used that stuff to take apart stuff that NOTHING else would move. Recently I had a rear spindle nut on an MV Agusta that a 3/4 inch air impact gun wouldn't budge(1400+ft/lb). Shot it with Kroil, and less than 5 minutes later it came loose with my 1/2 inch gun. Amazing stuff.

OK, guys- thanks to your instructions I'm soaking my barrel in Kroil- oops, I mean my AR's barrel! WB

one of these. unless your flash hider just came back from the salon you are wasting time with a hair dryer. i have a 3 temp selector heat gun. the 1st is a tad pricey for a single time user.
#2 is the cheaper way to go for single use items from HF.
the right tool for the job. OR
How much and How long..
is why there are competent, experienced, referenced folks to do it correct the first time (ok, 99% of the time, there are some things that just will not work with you ) so you don't post Can some one help me with this i had an oops??
