Mine's being renovated now, new barrel and manners stock, should come in at just about 7lbs full up. I upped the barrel profile a little, then had it fluted. The factory M7 barrel fouled pretty bad, shot sub MOA, but went to crap in about 15rds. I loved practicing with it, but hated cleaning the ^&% thing. It now wears a 20" PacNor supermatch 3 groove in 1:8. Right now it's at the smiths for bedding.
I was 1/11 in Fulda 87-90: Basic branch Field Artillery. Company FSO, Recon Survey Officer and platoon LDR.
I was 3/33rd Armor at the Rock, Kirch Goens. About ten years before you. 75-79. M60A2 crew and Company Ops NCO. Our sector was Bad Hersfeld.
