Ok, so I'm stuck between the vortex strike eagle and the vortex viper pst. The optic Willike be mounted on an m1a scout using a sadlak receiver mount. The strike eagle is about 180 dollars cheaper and has 2x more magnification. But it only has a bdc type reticle. The viper pst has better clarity, lower magnification, and an moa type reticle. Inside a range of 600 yards or so which would be a better option?
