ZREX,
I have and always use a monopod. It works real well in the close confines of a pop up blind.
Unfortunatly I don't recall the brand but it was ordered through Cabelas
I practice with it on the range all the time and it is very stable for me.

I had a problem using the bipod when in close quarters or in fairly heavy brush when having to stretch the to poles out wide. That's why I went to the monopod
