Elftmann -SE trigger help

Use blue Loctite on the set screws. That should solve your problem. The trigger will work and the set screws should not work loose.

I have one, set screws and anti walk pins, no problems after 800rds.

Any trigger play while its installed? Side to side?

I just installed an Elftmann SE (non-adjustable) trigger into my AR15. It’s different than the Geissele’s I normally purchase and requires set screws to put tension on the trigger group and hold the trigger/hammer pin in place.

So my issue - after install, trigger wouldn’t reset. I would have to manually push forward on the trigger to reset (this is all dry manipulation- not shooting). I took everything apart several times and re-read the instructions. There is emphasis that it is “absolutely critical” that the set screws are seated firmly. So I loosened and re-tightened (very tight) several times with no change. I played with it and finally found that if I just tightened set screws until they stopped and maybe a fraction snug- the trigger began to reset.

Anyone with experience with these triggers or similar installed trigger groups care to shine some light on my issue?
My concern is that the group could shift? and fail to function? Since it seems so finicky... or maybe I’m missing something...
I tried calling Elftmann -but they don’t answer

The only variable I’ll mention is this is a BILLETT receiver and I’ve noticed not all mil-spec parts work throughout the build

If tightening it causes the failure, the likely cause is that the holes are not drilled square to the receiver and the trigger is binding on the trigger slot once you tighten it into place.
One possible fix is to switch to captive trigger/hammer pins with use either screws or clips on the outside of the receiver.
This will eliminate the need for the setscrews to retain the trigger/hammer pins.

Another thing you can do it grind a flat on each pin right where the setscrew will land.
Then you install the setscrew down on the flat, but NOT tight.
Use Loctite to hold the setscrew in position.
The pins will be floating, but they will not slide out as the edges of the flat that you grind on the pin will hit the setscrew, stopping the pin travel.

This is is a good quality receiver set- seems unlikely it would have machining errors.

Then perhaps the trigger is machined crooked.
No matter which part is the problem, there is obviously a problem if the trigger is dragging on the lower.

I was going to check if it was an issue like this too-
I think it would be difficult for me to identify slightly crooked parts

it is absolutely critical to tighten the set screws evenly against the bottom of the receiver to ensure the trigger resets consistently. It is not hard at all to get them uneven. I have two Elftmann triggers and not had any issues with them, but have seen others struggle until they figured out they were cocking the assembly by not properly tightening the set screws.

Try the trigger in a different lower and see if it works.
