Issue with installing Geissele trigger

[Lazarus]

I'm trying to install a Geissele SD-3G in my lower. I put the trigger and hammer in correctly but then I couldnt get the safety in as the back of the trigger was blocking the hole. So I tried installing the safety in first and then the trigger. The safety went in fine and so did the trigger. However after installing the hammer the safety won't budge (its in the safe fire position). Breaking everything back down it seems as though once I go to install the hammer its pushing down on the front of the trigger and causing the backend of it to push up against the selector. Any idea as to why this is happening?

I have verified the trigger and hammer springs are facing the right directions.

What lower is it?

The safety is supposed to be installed first. That may not be correct with that trigger but on mil-spec it it impossible. I am not sure but it sounds like you have a problem. J/K

you might need to stone the back a little. It could be you got a piece that is out of spec a tad. Those two areas should act in co-ordination together.

I live in Acworth. Bring it over and let me take a look at it. I live right Hickory Grove Rd. If it isn't to much of a hassle.

Do not stone a Geissele trigger. Have you tried another safety lever?

I got it. I installed the trigger on another lower and while it was a little stiff the safety adjusted. I installed the safety first and was able to get the trigger under it. The hammer I noticed was cocking off to one side I dont know if the legs of the spring was sitting all the way on the pin properly or not but its good now.

What lower is it?

Its a CMT PDW lower and it has some quirks. Right now I'm trying to figure out how to install the rear takedown pin as the hole for the detent isnt in the normal spot
