WTH is a "mono" upper and DPMS does NOT make an AR10....they make a LR308. Armalite makes the AR10.I am reaching out to all INGO'ers to see if anyone knows of companies making a mono upper for a DPMS AR-10 lower. in my search I found Vltor and Mega arms however Mega will only fit their lowers. why I am asking does anyone have the vltor mono upper, if so what are your pro's & con's?
Thanks
