4140 steel 20" barrel with ambidextrous barrel extension
No more right hand - left hand barrels. New ownership fixed that problem. U.S. Veterans are running the show now. My rifle looks so much better and shoots better with this barrel. My Stag Dealer/gunsmith is the greatest too. Stag Arms customer for life. The ambidextrous barrel extensions shows me that this company means business.
