I installed a Geiselle SSP in my Stag 10.
I fired five fouling shots , which went as expected.
Then the trigger stopped resetting.
So I fired 38 handloads, single loading, with the mag inserted.

I had two handloads left, so I loaded them in the mag and the trigger reset itself .

Is it possible I missed something in the install? It my second trigger install.

Or is it possible my trigger has a burr, that’s hanging it up?

Hammer cocked, trigger didn't re-engage, couldn't fire the shot? Or hammer didn't recock, followed the BCG forward?
 
Not sure, but it sounds like the first scenario.

I insert mag, charge the first rnd, pull trigger and bang.
It ejects the empty case, strips another rnd off, then when I pull trigger, there’s nothing.
It feels as though the trigger only has about two thirds of the travel.

But at the end of my shoot, I had two rnds left over, so I loaded them in the mag, charged the first one, pulled the trigger, bang.
It then Stripped the second rnd and this time the trigger reset.

Can you take a pic of your trigger inside your lower?
 
I just picked up a box of cheap fusion ammo.
I’m going to see if the problem is still there.

As I said it worked with the last 2 rnds.

I’ll post a pic of the trigger group before I try it again

I have the same issue with bcl102 with Geiselle SSP so I installed G2S and no problem at all. I thought the issue might be the BCG slightly out of spec but it also might be the trigger(SSP). Waiting for my stag10 arrives so I can do more trouble shooting

I’m hoping it’s an install issue and not a manufacturer issue

Well just looking at that, and just to clarify I'm pretty familiar with the SSA-E, not sure if this trigger installs the same, but check the hammer spring?
However is looks OK? Ammo maybe?

I Stripped the trigger group out and reinstalled as per Geiselle instructions.
Also while watching multiple you tube vids.

Same issue, it will not reset the trigger.

I tryed it in safe and it was a no go .

So, what you think?

The only thing I can think of is to re install the factory trigger and try that.
 
Is it possible that there’s something wrong with the BCG? Or the buffer?

The trigger resets fine if I single load every round.
Also I find the charging handle feels really heavy, you really got to pull on that thing to get it load a rnd

So, does it cycle?, so the BCG isn't travelling back far enough to reset the hammer? is that what you're thinking?

Just thinking "out loud" if the ammo isn't powerful enough to return the BCG far enough to reset the trigger? that might be part of the of problem, however it does work when you single load?
Is it a brand new BCG? is so? you may have to shoot a few more rds to seat the gas rings?

Yes it resets when I single load.
Also when I use a 5 rnd mag, the first one fires, then ejects the case and loads a rnd.
But does not reset the trigger.
I then eject the live rnd and release the CH, it then loads third rnd and resets the trigger.


This happens with factory and reloads.

Also like to add, it fired the 105 rnds without a hiccup.
Using the milspec trigger that came installed in the set

OK, so when you "single load" you are releasing the CH or the bolt release? so you're getting the full effect of the BCG etc, however its sounds like when your using the mag, it goes back far enough to strip a rd, but not enough to reset the hammer? is the BCG in full battery when it doesn't reset the hammer? and if you have a FA, use the mag, and let it cycle and then try the FA and see if it goes in battery?

Or there's not enough pressure from the BCG to reset the hammer? but it travels enough to eject and load?

You could install the original trigger and if it works, then I guess you know the problem? maybe the Geisselle has a "heavier" hammer spring?

Geiselle techs said not to use this trigger in a AR10 platform, it’s more suited for an AR 15.
The recoil of the 308 is partially releasing the hammer.

Well, there you go. Put the factory unit back in until you can find an upgrade that will be problem free.

They told me my SSA-E doing the same was from to light of a trigger press and getting a double trigger pull cause by recoil...so the hammer was getting released and following the bcg home.
Mine only happens when shooting for groups from the bench.
