How do you remove forearm from Mossberg 500?

[leadcounsel]

I need quick instructions on removing Mossberg 500 forearm.

It appears theres a slotted O-ring that holds it on. Appears you just unscrew that and slide off forearm. Seems easy enough. Anything else?

Anyone wanna chime in? Thanks.

There is a slotted nut that holds them on.

Don't think there is an O-ring though.

Thanks, I mis-spoke. A nut is correct.

You'll need a special tool like this one:

Used a flat tip screwdriver, carefully. Already swapped the forearms. Thanks.
