+1 ^I also zero with 120SST at 50 yds out of a 12.5" *** barrel and it is about an inch high at 100 yds and close to zero at 150 yds. Using either an Eotech with 3x mag or Armasight Zeus 3x, so at that level of magnification its difficult to determine exact drop at longer ranges. Most of my shots are 40-150yds so with 50 yd zero it's minute of pig.
