  1. GUYS GET A FKN VISE AT HARBOR FREIGHT AND A MAGPUL BEV BLOCK. LESS THAN $120. Stop putting so much torque on the wrong parts of your rifle. The only part of the rifle that should be taking 30-80 ft-lbs is the star chamber. Do not use clamshell vise blocks. Bev block/ midwest industries URR only.

  2. I understand why your doing this, and I mean no disrespect. My concern is the stress on upper receiver. Of course I’d also never use that vise block neither, while I know that method has put together 100s of 1000s ARs still not the best way. Spend $30-$65 on a reaction rod of Amazon. Don’t risk the possible damage to the receiver.

  3. I did this for a Bravo Campany pinned castle nut 2 years ago to remove the tube that only used certain stocks (SBR I believe) to mount a standard mil-spec. Great minds think alike when we don't own a bench or block.

  4. Man, I’m in the process of building my first 300 BO AR, and this video came right on time! I want to put together my upper w/o needing a smith. I’ve already changed my muzzle device on my 556; 300 rounds through it since and no problems. Yeah, I’m gonna try this to get the rest of upper completed! 👍🏽

  5. Thanks for posting your video, dude. After wasting an hour trying to remove my A2 flash arrester using a vice grip and wood shims to keep the barrel from turning, I found your video and a comment suggested heating the muzzle device in hot water. I held the arrester under a stream of hot water at my kitchen sink for a minute, then I sat on my rifle and the arrester came off easily in seconds. I don't know if the hot water made things easiest. Regardless, you and @sinenkoalexander are the men of the hour!

  6. Did this and my whole barrel twisted and rifle wouldn't go into battery then ( didn't know the barrel stripped ) was putting my bcg back in the extractor pin sheered off, needless to say had to send the rifle back to smith & wesson obviously this method works i just don't know what i did wrong

  7. I just removed a muzzle break that was to tight from the factory. I was trippin over it. Used wd-40 around the thread area over night, wrapped the rifle in a moving blanket kneeled on it and super bingo!! popped right loose. thanks for the great ideas!

  8. I just used this technique to remove the muzzle device from a new Sig Sauer Rattler LT. I first submerged the end of the barrel in boiling water for 4-minutes, then used this technique. Worked like a champ!
