The tikka standard trigger is better and I was able to adjust it lower, all the way down to 1 lb 12 oz but I settled on 2lbs 1oz. The tikka trigger breaks better, no creep, and you don't have to take the gun apart to adjust it thats the best part. I like that I can dial it all the way down to sight the gun in. Then I can go back to a safe hunting trigger without takeing it apart.
Both 527 triggers I've played with are not consistent with the standard trigger. THey vary by about 3 or 4 oz. So if its set at 2lbs it may break as low as 1 LB 14 oz or as high as 2 lbs 2oz. The Tikka trigger is 2lb 1 oz every time.
an externaly adjustable rifle basix might be really sweet. If not the standard trigger needs a little work. The set trigger is great but set triggers have a long lock time. To improve the set triggers lock time you could use JNP striker spring its worth it.
The RB trigger isn't externally adjustable for weight I'm finding out after doing some research. It replaces the the set adjustment screw with a sear adjustment screw. On my particular 527 the trigger will adjust down to about 2 lbs 4 oz's and that's about it and as you have mentioned it will vary a little bit. The creep and overtravel is adjusted out and it is crisp on the unset position. Someone used to make a spring kit for the 527 trigger but I no longer have that link. Most of my shooting in the summer is paper punching at our club which I love to do. So I was looking for a trigger that was very light for the summer with no over travel. Some people here seem to like some overtravel but not me. The RB trigger isn't a total replacement but an improvement on the existing system. I just would have to remove the stock to get it from summer season to hunting season. Here's some more info on it. I'll try to find out something about that JNP striker spring that you mentioned. Thanks. Dave
