My youngest son and I bought a used Ruger target 243 and it had a Simmons mounted. It's a 6.5x20x40mm made in Korea. Can't find a model #, would anyone any idea what we've got. Has a duplex reticule, front AO which is very smooth, glass appears to be clear. Kinda hoping Simmons made an Aetec in 40mm, heard good things about them. Thanks olredhead
