Two stage AR15 triggers

[8'Duece]

What's the mechanical difference between a single and two stage trigger ?

I've had a Jewel two stage trigger factory installed set to break at 4.5Lps. Yes it's easy, there is no trigger slap, and for long range shooting it's easier to squeeze of a round and be on target than with my single stage triggers.

I haven't torn it open to see the difference mechanically than the standard single stage trigger so I was hoping that someone could splain it to me.

Disconnector different ?

Disconnector spring lighter ?

Trigger spring different ?

Hammer spring different ?

I don't have a manual and finding a blown out look at one on the net is next to impossible, at least in my Google fu hands. :doh:

I copied and pasted this in a email to the AR15 GOD and I should have a response soon...

Did you get the adjustable or the 4.5 set? I used a Jewel non adjustable on my NM service rifle and was super unpleased with it... Broke in the middle of a match

J. This came factory installed set to break at 4.5. I believe it's adjustable but I don't want to tinker with it till I know what I'm doing and how it differs from single stage trigger, mechanically speaking.

Thanks for the post and let me know when you get the reply the AR15 GOD.

So this is what I got back...

The trigger is moving a cam, which contacts the sear, its different in some triggers, or a separate spring adjustment for the two stages.


On a single stage trigger the trigger is moving the sear from the get-go as it's directly connected to it. Can be a long or short pull, but it's still single stage as the sear is moving as you pull the trigger.

All one-stage or two-stage triggers will very in spring lengths and tensions, it just depends on the maker.

The AR15 god has spoken!

Makes sense. Thanks, now I'll be looking for an exploded view of the Jewel two stage.

Thanks again.
