I have one that I took off my stainless M700.
It is about 15 years old and is pre X Mark.
It has been set at 3-3.5 lbs. Works great, I just replaced it with a Timney.
I have 3 of the 700 triggers that came off of the Rem XR-100's.
They are blued. All for $40.00 shipped,or $12.00 each plus shipping.
These are just the triggers, no bolt release or safeties.
