Been on the fence if I should jump on board with the zco scopes, the promo that is running right now hasn't been helping but I haven't pulled the trigger yet on one. Have not seen one in person yet and likely wont until if I decide to get one. But my question is this, I see zco 4-20 and 5-27 popping up all the time in the px. I read everywhere on the this forum how great of a optic they are and am confused my so many seem to be popping up. Are they selling to get the mpct-3 reticle? I'm not seeing many TT for sale but I realize there are probably more ZCO out there than TT due to performance vs price. Any insight would be appreciated.
