Thinking about buying a Manticore Forend for my EVO. Just how hard is it to remove the barrel nut?
This will be the only modifacation, with the exception of the charging handle, and safety switch, stock, pistol grip and maybe a muzzle device and possibly trigger parts. But the bolt will remain unchanged 
Black pistol disease... Blah

I only watched one video and the guy pretty much destroyed his barrel nut. |

Easy with the propper tool, a PITA with normal open wrench..
I did damaged mine trying to remove it without the adapter. ETA: Heating the barrel will help.. Leave a soldering iron inside the barrel for 5-10 minutes and you wont Damage the polymer handguard |

Worked fine for me with just a so 21mm open end wrench. Could also use a thin jaw crescent like bahco. You need a heat gun or simple propane hand torch like you would use to solder plumbing pipe and your good to go.
Drilled a hole in a round baking pan to use as a heat shield for plastic factory HG "heavy aluminum foil might work" and hit it real quick all the way around with propane hand torch and came right off. Use propane NOT oxy or mapp gas! Mine was smothered in red loctite but once you get it to actual 400 degrees it comes off like loctite blue |

I used a 20mm crowsfoot and a 3/8 long ratchet in a padded vice and it came off with a bit of force. My barrel nut was full of thread locker (did not use any heat) and I didn't damage it should I need to use it in the future. Not a big deal on mine.

From the varying reports some assemblers were more generous with the thread locker than others. Now there are products like the upper clamp and barrel nut tool that should make even the most stubborn nut a lot easier to get off. |

Put heat on it and a cows foot wrench and had no problem or damage to hand guard or nut.

Mine had loc-tite. Took the good advice to buy a cheap heat gun from Harbor Freight. Made it easy.

they all have loctite, you just need a 21 or 20mm? pretty sure it was 21 but anyhoo as preeviously suggest you will need heat to get it off. Mine has so much loctite I was brushing off chunks of it with a bronze wire brush once the nut was off.

Do two or three mag dumps, that will heat it up enough to remove the nut.
