4-16x40 AO. Bought May 2017. Est ~2500 rounds, 2/3 -.308, 1/3 - 5.56. Surprise failure to hold zero led me to wonder. All features worked; glass "OK"; all acceptable for a low-end product. [BTW: Wrong model listed on box end-flap.] Below avg shooter, but consistently hit 8" squares at 200 yds (.308). Advert as clearance of few remaining 2-yr-old model yr; hence I rationalized $69 price. Origin: Taiwan... You get what you pay for, -'brain dead' purchase, but probably fine for a .22.
