A friend of mine bought a Sightron S1 3-9X40 to mount on his Marlin 45/70Gov lever rifle and the glass is decent and it holds zero like a trooper but the eye relief was too short and with heavy loads it made him uncomfortable so I bought it off him and mounted it on my coyote rifle, which is a Rem model 600 in 6mmrem. I haven't shot anything but paper with this rifle so far ( just got the rifle also) but I think the Sightron and I are going to get along just fine. BTW, it has the Mil-dot reticle which is OK with me. I think I read that the Sightron scopes have some proprietary erector system in them that, according to Sightron, is the strongest tracking system in the industry. I usually try to avoid the bottom end of the line-up when buying optics but this time and one other I was pleasantly surprised. The other time I bought a Nikon Prostaff to put on a cheap rifle that I bought on a whim. I sold the rifle w/scope and wished I had kept the scope.
