Beretta now has section on their website for ARX-100, a semi-auto version of their ARX-160 rifle.
Some of interesting points are
Safety now moves 90 degrees instead of 41 degrees
Controls positions are similar to that of Armalites
6 sling attachment points
Magazine release is ambidextrous and can be accessed from three sides
Barrel can be changed between 5.56 and .300BLK with ease
Ambidextrous controls including brass ejection side with a little effort
Unfortunately, PMAGs cannot be used due to the shape of magwell and some other polymer magazines.
Price: $1950
