Help with M1 Abrams turret

[tankerken]

Note: no Muzzle Refrence System (MRS). Ours was turned in for repair but never got it back while I was on the vehicle.We just boresighted as usual. As gunner we shot 991 in TT-VIII.

Oh yea. The MRS on the 105mm was not much good anyway, too loose, and on the 60s we didn’t even have one.
