I pulled this 2-stage trigger group out of a friend's lower and nether of us know who manufactured it.  Can anyone provide an ID?  It may be fairly old.  Thanks for the assistance.

ETA - that is a "C" on the disconnector and an "E" on the trigger.

Well, it's just a modified stock trigger group, could in theory be set up to be a two stage but why?  A nice crisp single stage with no takeup or overtravel is preferable to most precision shooters, which is what the adjustments are there to do.  The takeup adjustment looks like it was brazed on, could even be a WECSOG project.

If you're interested in something like it, JP Rifles makes an adjustable trigger that's set up the same way with the adjustment screws.

Huh, interesting.  I don't really have a preference between the two and was more curious than anything else.  I think I'll toss it in another rifle and give it a try.  Thanks for the input.

That's definitely a single stage trigger, looks like the take up and sear release adjustments were added on to a standard trigger.
