I figured I could post this as there is a 2-stage trigger topic pinned at the top.  

I put a new respectible brand's 2 stage trigger into another new respectable brand's lower and proceded to work the trigger to work-in the parts.  I was very happy at first and then around the 40th try or so, my 2 stage became a single stage trigger.   Holy crap!

I'm thinking this is probly the triggers fault and not the lowers fault, as it was working right at first.  Any suggestions? or just send it to the trigger company?

Oh ya, this is a 2 stage nonadjustable type.

Thanks,

Brick

where you using any force to "work in" the trigger?

Yes a little, with my hands.

Just checkin'!
Sometime people can get a little overzealous with trigger boosting...

Is the pin that holds the disconnector into the trigger still in place?

My advice would be to contact the dealer or whomever you bought it from
and explain your situation...they will likely refund of repair the kit.
