Have a J&T upper that has an A2 flash hider on it, installed from factory. Trying to remove it, the thing won't budge. Tried putting a metal bar through the slots as a cheater, but still did not work. Flash hider is toast, but I don't want to mess up the barrel. Any idea how to remove this thing? I don't feel like getting a barrel vise just to remove it. Drill it off? Heat? Hacksaw? Secret code? Hmmm.

Keep trying with the metal bar, thats always worked for me.

What should I secure the barrel with to generate the neccesary force? I really don't want to mess up the barrel or handguards. Thanks.

This Or This Or if you really don't want to buy one of these wrap the handgrads with somthing to protect them and clamp it in at the handgards, just be careful not to tighten the vise too much and smash the handgards.

... These are NOT rusted bolts on an old Ford in your backyard. You can negatively affect performance of your rifle by over torquing (either on or off). Don't fuck up your rifle, I would try a little heat. It appears J&T may have used a bonding agent, if that's the case 250° to 350° F will do the trick.

... Or you can ignore me and find a longer cheater bar

Put the FSB against a desk or something so that it pushes into it when you twist.

I use a crescent wrench on the flats of the FS, and hold on to the receiver while I twist, worked fine for me.

Winston- would not dream of ignoring you. Already fucked up the flash hider, I do NOT intend to tank the barrel. Will try application of a little heat. Rather peeved that JT would do this. Was a preban after all.

A good trick I have used is to take some hardwood and drill out a hole exactly the diameter of the barrel, then cut the block in two. Now you have a hardwood barrel vise. Probably won't last through 5 barrel clamps, but it'll work for one FH removal and it won't hurt your finish.

YMMV.

I agree sith Winston_ put some heat on it..they could have used some type of locktite or epoxy. after removing the set screw on my FH I had to heat the epoxy to remove it totally

Are you sure the flash supressor is not permanently attached? I had a J&T upper that had a muzzle brake attached with a blind pin. I had to dremel the underside of the brake to expose the pin and then unscrew it. But it usually takes the proper tools. I don't think I could have taken it off if I didn't have an action block and armorer's wrench (not to mention the dremel).

Well, I would hope it was not permanently attatched. It was sold as a preban, so if they pinned the flash hider they owe me a new upper.

DONT EVER use an action block to install/remove a tight muzzle device. You will damage your receiver/cant your barrel by putting all that force on the tiny indexing pin and aluminum reveiver slot. Use vise blocks on the barrel, or vise the FSB between wood blocks....

Well, the heat did not work. Am now in the process of dremeling it off, but am worried about hitting the threads or the barrel itself. This is very frustrating.

Aaaand hit the barrel. I can't believe it. Have I ruined the barrel? Dremeled about 1/16" into the end of the barrel past the threads. I don't know what the hell JT used, but this thing is really stuck on. Not having a great day.

This why there are gunsmiths. Now how much money did you save doing it your self?
Link Posted: 9/21/2004 10:29:39 AM EST
Yup. Lesson learned. I suppose I should be shopping around for someone to undo my "oops." Any suggestions?

thanks,
