Hello- I?m new to this caliber and at the moment just have a Mil-spec trigger in. I added some JP trigger springs. It fired Hornady fine but was 50/50 or a little better with wolf harder primers. The trigger seemed to have creep and just didn?t feel right. It?s back to all Mil-spec now. Just wanting to see what was out there that gives lighter (crisper) trigger pull and will still work with Wolf. Thanks

Ssa-e works 100% with any factory ammo from my 2 ar grendels.

Same with the LaRue MBT-ees.

You need the JP 3.5T springs. The T is the heavier hammer spring for reliable ignition on harder primers. Grind down top rear of trigger that engages safety. Grind about .040-.050” off. Install set screw through pistol grip bolt hole to take up creep. Takes about an hour total and $12. If you have experience stoning trigger surfaces you can also stone with a white India stone and really make it nice. I do this on my utility carbines/pistols. Target guns get Jard fully adjustable.

Ricsmall speaks truth.
I have done up a few Anderson NB triggers with the low power springs and trigger adjustment screw sold at joeboboutfitters and it does make for a perrty nice single stage.
If done right it will come out in the 2 1/2 pound range. Used one for a bit and it ran the wolf ammo just fine.
If you can swing the money a true 2 stage like the Larue are the ssa-e is going to be the best of both worlds. Eats cheap steel cased and nice and smooth light breaking for more serious target/hunting work.

I have the Larue 2 stage and it shoots all my 6.5 Grendel ammo, including Wolf, as well as other calibers, including 7.62x39 Tulammo, just fine. I did add an enhanced firing pin to one of my lowers though once I ran into some issues with the 7.62x39 and have not had a soft strike failure since. I got a great deal at BlackRifleArms.com. Not sure if it is still on sale or not, but that slightly longer firing pin can make a difference without having to have strong trigger springs.

With the AR-15 in 7.62x39 the enhanced firing pin might be a benefit but I would be hesitant to use one in a 6.5 Grendel without checking the firing pin protrusion. There have been issues with 6.5 Grendel bolts overall length and firing pin lengths not playing well together. You get out of the spec for firing pin protrusion you can get light strikes with a short firing pin and slam fires and pierced primers with a FP which protrudes to deep.
I suggest you measure the overall length of your bolt and firing pin to ensure they are in spec. Brownell?s sell a FP protrusion gauge and minimum is .028 max .036.

The light hammer spring with a standard hammer weight (not bobbed), combined with cold weather and harder military primers is a recipe for light strikes/FTFire.
You want a full power hammer spring for reliable ignition of primers.

Larue MBT as others have pointed out, It is a 2 stage but it comes with 2 springs, I would suggest the lighter one

Op
Be careful playing around with modifying your triggers. A lot of time reliability goes down and liability goes up.
I use a standard GI trigger on mine and never had a lite primer strike.
