Can we make a thread that gives the maximum effective range of various length uppers? I'm building an SBR and that has prompted me to ponder this. We'll define maximum effective range as distance at which you can expect reliable fragmentation.
I'm sure as a forum we can come up with some adequate figures for the M193 round.
I'm sure this would be helpful to many. I know I'd like to know
Thanks to those who can be of help.
I'll try and up date this post with the info as we go.
