Replacement Elevation Turret for the Brownells Match Precision Optics (MPO). The Extended Range elevation turret does disable the zero stop mechanism of the turret but it allows for full range of elevation travel. A great upgrade for the 3-18x50mm MPO to squeeze the most adjustment out of the optic but fits either the 5-25x56mm or the 3-18x50mm MPO rifle scopes. Mfg: Brownells
