The Geissele 2 Stage (G2S) was designed to be a high quality, cost effective alternative to the SSA.  It is a 4.5 lb. non-adjustable precision combat two-stage trigger and allows precise and accurate trigger control. The G2S is manufactured from the same tool steel as the SSA. Visually, from the outside of the weapon there is no difference from the SSA and the feel and reliability is the same. The G2S however has a different way of holding the hammer pin in place. There are no laser markings, and the parts are only spot-checked for MP. The G2S Trigger will lighten the trigger pull relative to a standard trigger. This lightened trigger pull will make the firearm easier to discharge.

Nate S on Dec 2, 2019
BEST ANSWER: I have never used the palmetto 2 stage. But judging by their other triggers I couldn't imagine it being anywhere near as good.
Will this fit the pa10 gen 2?
John Doe on Apr 19, 2019
BEST ANSWER: Yes. Most triggers can be used between AR-10s and AR-15s. I have this Trigger in my DPMS style AR-10.
Does the two stage mean when you pull the trigger it fires then when you let the trigger up to reset it fires again ?
Tom L on Jan 3, 2020
BEST ANSWER: No. Two stage triggers have two parts to their pull; the first takes up the travel until just before the trigger is ready to release; the second stage actually lets the hammer drop.

super trigger
The single biggest improvement in the firearm is the trigger. Reduced my groups significantly.

When it goes on sale buy one for every lower you own.
Awesome trigger. I got this on sale for $100 and I will probably buy another if it goes on sale again. I also have a larue ltmbt 2s and I like the geissele marginally better. But both are light years ahead of a standard mil spec trigger.

Trigger every Ar should have out the box!
Nice clean break. This is what every Ar should have right out of the box! I have a few aftermarket triggers and run mil-spec ones also but,this has a nice clean break not to heavy not to light. Nice two stage. I have another build coming up and this will be the trigger I put in that one also! As always PA shipped fast definitely be back for at least one more!!

Sick! The Geissele G2S has totally delivered for me. It’s true what they say: once you buy one, you’ll be buying more for your other rifles. It’s a curse (but a good one). Happy to buy again, killer price.

Palmetto EPT is good, Geissele is way better
Totally unbelievable the difference in this trigger and a pretty good trigger (the EPT that it replaced). Won't know what you are missing til u try a Geisselle. It is not just good, it is perfect every pull. EZ to install for anyone with mechanical aptitude.

The Palmetto EPT is plenty good enough at the price point of the rifle. Had doubts about replacing.

Overall, well pleased with the upgrade. Not a necessary upgrade, but money well spent.
