Burris m-tac 4.5-14x42. Had the 1.5-6, loved it but decided to go with more magnification. Got an awesome deal on flea-bay. Pepr mount is great and all but it isn't light if your concerned about weight at all. Met a fellow at my local range, let him shoot the 10 and he fell in love with the scope (Burris m-tac 1.5-6)offered to buy it. Made upgrading much more affordable. 1.5-6 power is great for 223 or 556. Let's be real we all bought the 308 because it's a more capable round so get some real magnification on it from the start, you'll be glad you did.
