i don't have the tools .anybody willing to do this for me? lmk i'll pay

What tools are you referring too?

Magpul kit should come with the tool necessary to remove the forend.  Also what model Mossberg are you trying to do this too?

I swapped out the forend on my 590A1 a couple of months ago.  PITA because the nut hadn't been off for quite some time, but I did it without a vise.

From the linked article in the OP....

If you have one of the Mossberg shotguns with the shorter action tube, all factory 14" SBS M590A1s and most 3.5" chambered models, you have have been disapointed when you found out the MOE forend dosn't fit. People with 3.5" chambered guns have options, the easiest being to just order the longer action tube, but if you have a SBS the longer action tube won't even fit on the gun. Magpul still has the only mounted photo on the Mossberg MOE page showing a M590A1 SBS with the MOE forend despite the fact that it is not a direct fit, not even close.

I modified two MOE forends last week to fit my two SBSs once I got the measurements and thought it through. First off, the forend needs to be relieved at thee rear to clear the tension spring between the tube itself and the bars. As shipped, the action tube won't even slide all the way in the MOE. It stops about 1/8" short of the molded in ribs of the MOE. Clearancing the MOE on both sides lets the action bar slide all the way up against the ribs like it is supposed to. This should be an issue on any 500/590 series; 14", 18", 20"... and was mistake on Magpul's part. To address the length I first used a 1 1/2" hole saw to to the rough work. It is a very snug fit and was pretty much self centering. It bottomed out after cutting in 1" so it got me most of the way there.

I have a mossberg 500a. I need a hole saw and dremel to modify the  forend. I can remove the forend but the magpul part requires the 73/4" slide. Mine has the 6.75" Slide. I need someone to trim the excess off the forend. The proper way to do it would be to buy the longer action slide but that runs about $50-60.

I'm a cheapo lol
