Add To:

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.

Geissele triggers are brilliant
Try a Geissele and you will learn why they have such a loyal following. Trigger action is smooth, light and crisp but very predictable and enables perfect control. After installing and running this trigger for the first time, I immediately ordered another Geissele for my competition rifle, and was impressed again.

by far the best at the price
This is my second unit. The Geissele two stage is the best for us old milatary guys. The take up is an extra safety feature. The second phase is as crisp as a single stage. Can't be duplicated at the price!!

Awesome Trigger Great 2 State Option
This trigger is amazing because the first stage wall is very tactile and the second stage break on this trigger is super crisp and predictable. I use this lower with other uppers when sighting in optics because it breaks so clean. I liked the first one so much I bought a second for one of my other target lowers. Can't beat the price for a high quality 2 Stage Geissele.

The GS-2 trigger is absolutely the best upgrade to a mil-spec trigger!
I dropped one of these into my Sig M400 and wow, what a difference! Results at the range improved dramatically! Giessele's support is first rate.

Great target trigger
I group better with this than the 4 pound single stage I was using. It’s the best of the three I’ve used so far.

Best bang for buck!
I have 5 of them. Ive had a lit of other triggers but once these are broken in, they are hard to beat.

Good purchase
From a Mil-spec to this G2S trigger it was a big difference. If your looking a a smooth light pull. Check this trigger out. You can also find install videos on YouTube. I also added the Geissele super 42 spring big difference.
