40-X rimfire trigger question....

[tspearsrph]

Are 40X rimfire triggers and 40X centerfire triggers the same (and interchangeable)? I have an older 40X rimfire (from CMP) and the trigger is different from 700 triggers. There is a long vertical
screw that holds a small "ball bearing" right in front of the trigger shoe. Can I replace this triggewith a standard 700 trigger? How do you adjust the old 40X trigger, since the adjustment screws are different format than the 700 trigger's arrangement? Thanks in advance.

It's likely you have a 722 based 40X Rimfire. Is the bolt handle straight or dog legged?

That long vertical screw on the front of the 722-style 40X triggers is the adjustment for weight of pull. It's quite easy to get these triggers down to less than 2lbs using this adjustment.

I tried a Timney Calvin Elite on my Jelrod-modified 722-style 40X repeater, but couldn't get it to perform consistently. Had the same issue with this particular trigger on a Stiller 2500XR repeater. So I sat this CE trigger aside & replaced it with Jewell HVR triggers on both the Stiller & 40X, and have not had a single issue with either.
