Just a follow up on my choice. I went with a Sightmark 4-16x44. About $250.00 but wow, you get A LOT for the money. It is a second focal point but you have to expect it for the price. It comes with mil-dot, red and green highlight reticla for those late almost in the dark shots or leave it off for good old black dot. Turret locks are also standard.
I love it, buying another for my other rifle.
OH, one negative. The sight adjustment and manual says 1/8 MOA per click. It's 1/4 click not 1/8. Sight mark says they changed all the info but check inside the box before you buy.
I ONLY buy things from companies I can reach when I call. They have always been there, answered questions and the tech team walks you through everything you need.
