I am looking to build my first ar but I can't find a left hand upper does anyone have any suggestions or an extra one laying around
Have you tried Red X Arms
Just order one from Stag with bolt carrier group. Five of my AR's are built on LH Stag uppers except the sixth one I built on a right hand upper.
I have a Stag Arms upper , complete with BCG ,Charging handle , dust cover and forward assist
New In Box
Also have a Stag lower and LPK
PM if interested
White Oak Armament makes left handed uppers.
