    Left hand FDE Receiver assembly.

    I put a 16.5” 6mm ARC BBL and a 15” FDE hand guard together and matched it up with a SA FDE lower receiver to build my first complete FDE carbine. I haven’t shot it yet but I really liked the way it looks.

    Left Hand Upper

    I picked this up because my son is left handed and I’d like him to not get blowback in his face. The quality of Stag Arms has significantly improved since I last looked at them. I was impressed and will be considering other products for future builds.

    Very good quality. Did not realize the ejection lort opened upward. Changed it out for two reasons. First being that I wanted a tan ejection port cover. Second reason was because the ejection port pivot pin stuck out too far and I was not able to mount my Aero Precision handguard.
