Just got a Timney 510 trigger to replace the one I had in my 700. I am a little disappointed because the Timney is fixed a 3lbs+ and I am used to under 2lbs. I had to replace it because the bolt release tab broke off. Does anybody know the manufacturer of this trigger? The only marking is the number "1" seen pictured. It is hard to believe it is factory because it is so light.
