Benelli M2
I built this for 3 gun but never got into it.
23" barrel cut down from 28" and rethreaded for Winchester chokes-local shotgun smith did this work
Nordic Components mag tube mag tube clamp, and charging handle
the carrier has been lightened and hard chromed-can't recall who did that
the lifter has been welded and plated by C-Rums
the loading port has been opened up for easier reloading
