If this question has been asked I apologize. I am building up an 870 and would like feedback regarding a forearm with rail. I will mount a forward grip and light. The links below are my first thoughts. The one from cdnninvestments is inexpensive, but who knows might be a find. Number one priority is solid lock up, dont want loose wobbly attachments. So please give me your advice regarding items below or tell me what your running. PICS would be great. Thanks

Both are very bad ideas. A vertical forend will severely damage your weapon. We all tend to torque the forend. I can look at your mag tube and tell to which side you torque. That vertical forend acts as a lever and increases this torque and will twist your action bars. The action bars then start to bind inside the receiver and can even do damage in there. The forend tube assembly for the 870 is $35 and you will have to replace these regular if you want a smooth working shotgun. I have received weapons in for repair that had these on them and the forend tube assembly is always damaged beyond repair. One action bar is twisted in and pointing up and the other twisted out and pointing down or visa versa depending on if the shooter torgues clockwise or counter-clockwise. I can bend them back but metal like that once bent will always return to the bent state.

The rail mounted on the forend is also a bad idea. After your hand gets cut you will understand. That little pictinney rail attached can reslut in some stitches if you are not very, very careful. Get in a hury and you will find out the hard way.

Look at the rail brackets from www.cdmgear.com (http://www.cdmgear.com) or other types for a safe way to mount your light.

I agree with the above. Also they add a lot of bulk with no real benefit. There is a reason you don't see shotgun trainers or other professionals running vertical grips.
