I'm a newbie with the Mforgeries and I'm having a bit of a problem with the
free float tube. I have an RRA w/ a factory installed YHM free-float tube. Its very
heavy so I bought a DD 7.0 rail and I am trying to swap them out.
Following the BA (bad azz) instructions (in reverse) for YHM free-float tube.
I have all the proper tools. punch set, bushmaster upper holder,
DPMS multi-tool etc...

I have the suppressor off.
I removed the A2 FSB and gas tube.
I loosened the YHM locking ring.
now.... the YHM free float tube should just unscrew. Right?
I can't budge it!! I have it mounted in a vise.
--- The answer ---
Loctite --- I emailed YHM and was told the FF tube should just spin off
but that RRA probably pre-installed the FF with Loctite. So according

Q: How can I remove a fastener that is "permanently" locked in?
A: The application of heat is needed to remove a fastener that can't be removed with a hand tool. Temperatures of 325F and above is needed to break down a standard anaerobic, 500F for high temperature Anaerobics. A heat gun or propane torch is commonly used to do this process, and careful disassembly should occur while parts are still hot. Once apart, and cooled, use methylene chloride (Chisel #79040) to remove cured excess material. Always wipe down the fasteners with clean up solvent to remove the wax film that Chisel leaves on the surface.
hopefully this will work and provide some advice for other complete newbs like
