OK....I've tried to remove the Flash hider on my Colt preban CAR but it wont budge.

Did colt blind pin their FH on ? I thought it was only held on by torque and locktite.

Any suggestions would be appreciated

I'm not aware of any blind pins. You never know with Colt, though. I assume you have the barrel death-clamped in a vise close to the flash suppressor? Good. Now its time to get barbaric. Put the barrel/upper in the freezer over night. Then reclamp that barrel (close to the f/s to keep the barrel twist down.) Grab yourself a little map gas or propane torch. Either one won't put out enough heat to damage anything. Heat that f/s up from the outside, in the center, and as fast as possible. This way you will keep the heat in the f/s. (But make sure you get the threads hot as well) If the heat bleeds into the barrel you are defeating the purpose. Make sure the wrench you're using is a tight fit around the f/s because now you've got to hate torque the thing off. Make sure you have your work area ready to go so you have minimum idle time on the barrel. FREEZE...HEAT...TWIST! May the force be with you.

The first time I removed the A2 hider on one of my preban Colts I thought they welded the damn thing on. It took a [b]lot[/b] of torque before it finally came off, but it did come off. They don't pin prebans, but I'd almost swear they use an 800 pound gorilla to put them on. I just wasn't being medieval enough.

OK...I know the concept....we use the hot/cold process on jet engine bearings etc. One more question.....We are talking counter-clockwise (as looking down into the muzzle) to remove it....right ?? Just wanting to make sure :-)

Yep. Lefty loosey, righty tighty. Had the same problem with the A1 flash suppressor on my SP1. Ended up leaving it as is.

Yes, medieval.
