A quick question, and hopefully a quick answer..

I purchased a 930 Tatical with an 18.5" barrel, I also purchased a Nordic Magazine Extention. I read through the instructions that were provided from Nordic, I've goggled, and searched tons of forums, but could not find any instructions on how to remove the stock parts under the magazine clamp, does anyone have any available , does it require special tools, here is a picture of what I'm talking about

I've not tried to remove mine yet but if it's like others I've seen it's just pressed into place and can be removed by carefully pulling it out with a pair of pliers.

There are other's here with more knowledge than I on this. I'm sure they will chime in soon.

You can use a flat blade screwdriver and walk it out, be careful and use some sort of protection on the mag tube.

I start at the split and work my way around.
