I've seen some polish underfolders with a slight downward angle on the stock when unfolded (similar to a Norinco underfolder), but most are straight.  I've always liked a little bit of a downward angle instead of having the stock fold straight out.

Is this something I can adjust during my build?  Is it "wrong" to have a polish underfolder with the slight angle when unfolded?  Correctness is always more important so I just thought I should ask.

I just ordered my underfolder kit for my first build.  I'll probably use a 100% receiver unless I can find a build party in my area... I don't have the tools to bend a flat and weld the rails.

thanks
