NoExpert beat me to it, M25 was discontinued so along goes the Rader Trigger with it. I was interested in one for along time but read a lot of mixed reviews on it. I am a light trigger junkie and would love a lighter pull weight for my M1A. I have used a Jard 1.5 on an AR and only encountered problems with the trigger itself no doubles, if you know what you are doing it is fine. I have since switched to a JP 3lbs model and it is very adequate for what it is, most importantly it had never failed! I like the idea of a 1.5-2 lbs model for the M1A for precision work. Yes it is not safe to work a GI trigger below 4.5, but I would really like to see a drop in model made specifically to address the issues with the M1 trigger. A well modified NM M1 trigger is great, but a lighter trigger would be even better for my purposes. I do not shoot in matches, mostly benches and ranges prone and such. The Rader is the only option I have ever seen keep an eye out in the for sale sections and gun auctions site if you want one.
