You need a heat gun. The job is easy. I've done two of them. Remove the spring retainer, spring, follower and the limiter. Pull the barrel, trigger group and bolt carrier assembly.
Put the receiver in a padded vice. Direct the heat inside the receiver where the stock mag tube is threaded into the receiver. You may need 5 to 15 minutes of heat. The locktite will start to smoke when it is releasing. Every minute or two, try to untwist the stock tube by hand. A strap wrench isn't needed because you don't want to over torque the tube and twist the receiver. Hand strength will limit the torque you can apply.
When it starts to release, the tube will unscrew about 1/8 of a full turn, then stop. Apply more heat and repeat until it is removed.
When it is out, the receiver will have white dust in it around the threads. Clean this all up. Acetone works well. Essentially, it's powderized locktite.
The bracket for the handguards is held captive by the tube, transfer it to the new tube.
It is up to you if you want to apply locktite to the new magtube. I rather easy removal for deep cleaning routines. Simply thread the new tube in with the handguard bracket in place. Tighten the tube firmly. Drop your follower in along with the provided magazine spring. Install the spring retainer with a pair of snap ring plyers. Reassemble the weapon. Verify seven 2 3/4 shells fit in the mag tube. If the last shell won't fit, trim a half coil from the spring until it does.
Hope this helps. It's an easier job than it sounds. Assuming you get the right tools. Heatgun (not a hair dryer), snap ring plyers, acetone, wire brush to clean the receiver threads of locktite.
