3.5x15x56 nightforce is 30 ounces, the meopta 3x12x56 that has been recommanded is 21.5 ounces. and the smaller 3x10x40 some pepole are recommending are 15.5 ounces. the math tells me that that is only 1 lb, not 3 or 4 lbs . i think that the 30 mm meopta or the nikon 2.5x10x56 will be the better choose than the 40mm. and they are both in the price range bill collector is looking for. i only threw the 3.5x15x56 nightforce in because of lighted reticle and the old bullet proff models can befound for 800 or 900 dollars. as i said before i would not let 1/2 pound or 1 lb stop me from getting better optics
