It is for a 270 Ruger. I had a Bushnell Dusk to dawn 6-18x50mm andliked the light gather'nand the high power. I do alot of long range shoot'n 300+ yds. I put my old scope on my .17 hrm and now need a new scope for rifle season. I think I am gonna go with the Elite 3200 5-15x50mm. I can get it for around $265. Thanks fo rthe replies. Chad
