I'm going to purchase new night sights for my SA Champion Operator but not sure which exact ones I need. I know they're fixed low profile Novak cut sights but I just don't want to buy some online and they be the wrong sights. I'm leaning toward Meprolight night sights at the moment. If anyone has any thoughts or answers on the exact night sights I need please respond. Any brand I don't care I just need some help here. Thanks "Queen of Battle"
