I have a Mossberg 535 and the spring inside the mag tube is bad and I have no clue how to remove the tube to replace the spring. I've took the whole gun apart and twisted with no luck. Mossbergs manual wasnt helpful either. Any help would be appreciated! Thanks!

You need a special tool to remove the mag tube from a Mossberg. Brownells sells them for around $35 plus shipping. You also need the cap and pins. The total will be around $50. You will likely come out cheaper getting a gunsmith to fix it for you.

Dude you don't have to unscrew the tube to get access to the spring. When you take off the cap in the front and remove the barrel you will notice in the from of the tube there seems to be a cap that looks like it won't come out because the end is crimped get a large flat heat stick it in that cap and screw in about 1/8 of a turn do that the notch in the cap lines with the crimp in the tube and pops out mind you, you need to do this pushing the cap in a little. Once the cap comes off just pull the spring out and follower. If you feel the spring has lost some tension give it an attitude adjustment and stretch it out a bit to gain more tension. You don't need any special tools. The only reason to take out the mag tube is if it's bent or dented because it can cause feeding or loading issues.

Did you try to screw it in a 1/8 inch like I said to line up the crimps with the notches in that cap inside the tube. I know it doesn't look like it comes out but it does.

Yeah, the screw is attached to the barrel. And I can't twist the tube at all. I'll see if I can upload a picture. I'm more visual learner..

I recently removed the tune from my 500. Had to pad my bench vice (I used thick leather) and used a strap wrench and worked it back and forth till it loosened. Don't be in a hurry, be patient and it will come.

They make magazine extensions for a mossberg but you have to use an aftermarket barrel. Brownells sells the kits. Your gun looks weird with a magazine tube that is a foot longer than the barrel.
