That "sounds" like the older RS1 trigger, not the RS2. RS2 has two adjustment screws. What's the model number on the rifle? If you can't find it, look on the box where the bar code is, or near the specs. Should be some numbers in there like 1050-1051- etc.
Well dang...So, is this a direct drop in trigger, or is the mechanism different too? In other words, is there a CharlieDaTuna type of upgrade here (I don't see it listed on his site)?
