My Rs2 shoots great. My gun likes crosman premiers the best, i can shoot penny size groups at 25 yards when i'm doing my part. The trigger are my gun is first and second stage adjustable, and i believe yours is too. I think the trigger on this gun is sweet. I have the Rs2, but it has open sights also and comes with two barrels. Rs2 sportsman is stamped on the reciever. Make sure all your screws are tight and your gun will group nicely. Mine wasn't penny size at first but after 2000+ pellets through it, it's amazingly accurate. If your guns has the adjustable trigger, set the trigger to the way you like it, and your groups will shrink more. Here is a group i shot at 25 yards. Also, if you want the best performance, try as many pellets as you can. My gun is very picky, and most cheap pellets don't shoot well. Matt
