This precise, easy-to-use scale makes custom trigger work easy. An
excellent tool for the do-it-yourself gunsmith or the shooter who prefers to
set all his triggers to the same pull weight. This precision scale accurately
measures the force needed for trigger release of firearms. (Accurate to
+/- 2 oz. in 2-oz. increments to 8 lbs.) A sliding indicator remains at the
highest reading when the trigger releases.
The RCBS trigger scale does a pretty good job of testing trigger pull / lbs. But I think that the rod should be locked into one postion. I didn't like the way that while pulling on the trigger, it wanted to twist to one side, thus making it seem hard to get in the center of the trigger. If I tested the same trigger twice in a row I would have a slight difference. I feel as though the accuracy may be off just a slight bit. Over all it does give you a close idea of where your trigger lbs. are. For the money I thought it was worth it.
