i'm having trouble removing the forend nut on my remington 870.  any ideas on how to get the nut loose.   thanks

If you aren't installing a Surefire fore end, make your own tool.  

Surefire provides a tool when you buy their forearms.  It's nothing more than a flat piece of sheet steel about 0.1" thick that fits into the two opposing grooves in the nut.  It spans the full width of the nut.  You place it into the two opposing grooves and turn the tool with a crescent wrench.  It's equivalent to a GIANT screwdriver.

You could also use an aluminum sheet but it might bend a little.

OR...a pair of pliars padded with an old leather belt...works for me.

I could be wrong, but you guys are talking about ways to remove a stubborn magazine cap - I believe he's talking about the fore-end tube nut...

In that case, what I did was cut a piece of 1/8" thick steel to about 1.25" x 1.25" - I then clamp a pair of vicegrips on that, and put a wrench on the vicegrips for turning leverage... It also helps if you soak the nut with a penetrant like PB Blaster or Kroil for a few days beforehand - it might be rusted on a little... I have also carefully clamped the draw bars in a vice when performing this operation, but that could trist them a bit if you're not careful...
