Hey guys i just got a decent deal on a eotech 516. Total cost was 398.05 with free shipping after the 5% off at optics planet. This is my first red dot. Im mounting it on a colt 6920 carbine. When im lining up dot on the target do i need to always align the dot with front sight? Use just like the dot is serving as a rear sight? Wanna kill these ads? We can help!
