Hello guys
I installed a Geissele SSA-E trigger as my first modification. I didn't like the original trigger.....too much creep and too heavy pull. My pull is now 3.0 pounds and the trigger breaks nice and crisp. I used the hammer spring from the original trigger as the Geissele spring seemed way to heavy. My rifle works perfect now. I wonder if anybody used the Geissele hammer spring and if so..what tigger pull do you get?
(I could try it myself, but my range is 30 minutes away, and I don't want to find out that it doesn't work so I have to go back home and reinstall the S&W spring)
Appreciate any answer!

The Geiselle spring is designed for reliable ignition. The trigger pull is just fine with it installed. It's never a good idea to lighten the mainspring on a weapon you might use for self defense (or hunting). I suppose in a match, all it costs you is time

The energy for ignition is almost completely dependent on the mainspring. A heavier hammer is slower, but has the same energy at the point of impact. The Geiselle hammer is lighter than the OEM hammer, and with a heavier mainspring, yields a very shot lock time.
 
I have one AR with the regular SSA and 2 others (3-gun AR and my competition 15-22) with the Super 3-Gun trigger. What I have found, and it may or may not apply to yours, is that changing one spring out in a Geissele often times makes it fail to work properly while changing them out with a set will work. If you have not shot the gun yet you need to shoot it without any "custom" touches first to break it in. I personally would put the Geissele spring back in for at least 500 rounds before I started playing around with it. I have successfully installed the JP "yellow" spring set in the S3G for a measured pull of 1.25 lbs that worked perfectly but took it out for safety reasons (did not want to get any ADs in a match). Stock springs give a pull of 2.5 lbs in a 15-22 and that is just about right. Have not tried an SSA or SSA-E in a 15-22.
 
My concern is that .22 LR is not powerful enough to push the hammer back when I use the Geissele hammer spring. My set up with the OEM spring works perfect with all ammo except subsonic, where I got failure to feed all the time. ( The manual don't recommend subsonic ammo for that reason) Just now my philosophy is "if it ain't broke..don't fix it". I have shot around 1000 shot like this with NO light fire stroke or FTF. I asked Geissele if they had any experience with the SSA-E trigger on a 15-22 and they said it should work. I still think their hammer spring is very strong in order to work perfect on a AR 15 (center fire rifle). Hope I could explain my concerns properly.
Any body out there with actual experience??
Thank you for all opinions!

I have an SSA in my AR, but not really wanting to put that much coin in the 15-22. I tried the JP Yellow springs, but really didn't notice that much of a difference, to be honest. Other than my bolt failing to lock back on an empy mag, that is. Anyway, put the stock springs back in, but haven't had a chance to shoot it since swapping back, to see if the bolt locking back issue went away.

I have the CMC drop in trigger, and all I shoot is subsonic... around 8,000 rounds a year. Can't even remember the last time I had a failure of any sort using that trigger. I tried a Timney before the CMC, and it caused all sorts of failures.
 
I put a G2S into a Colt AR. Very nice, about 3.5 pounds. I had a spare Jard non-adjustable with 3# spring which I put into a 15-22, getting about 3.5 pounds. No mods in either case. The G2S is definitely the better of the two but both work just fine.

I understand that the ALG trigger is actually a Geissele single stage under a different name, and very reasonably priced.

If it's one thing that the typical AR type rifle needs right out of the box, it's a better trigger.
 
Final Results Hammer Springs

Which hammer spring did you end up leaving in the rifle? I just installed the SSA-E in my 15-22 and haven't had a chance to shoot it. The Geissele hammer spring is considerably stronger than the stock hammer spring.

I recently ordered and received two of the longer trigger and hammer pins from Geissele. One of the guys that works there told me this:

"Thank you for contacting us. The hammer pin will rotate in any rifle while the trigger pin will either not move or barely move, this is normal. You can certainly still use our hammer spring with the .22. However, you may need to go back to the stock hammer spring as our is a full power spring and it may not blow back far enough to reset the trigger."

Hopefully I will have a place to shoot pretty soon and I can try both springs. I have the SSA-E in my DD V7 Cerakote 5.56 and I love it. Of course two different things. Let me know what you ended up doing. Thanks.

Have got the CMC AR flat blade drop in (3.5lbs) - I honestly don't know why anyone would buy anything else, especially ones that come in bits? If I had to keep one mod only on my 15-22, it would be this trigger (only imho)

Because that trigger is not particularly good for speed shooting. Nobody uses that trigger in 3-gun shooting so nobody tends to want to use it for shooting a 15-22 in Steel Challenge or Ruger Rimfire (NSSF Rimfire now) either. A great trigger for a Slidefire stock (Geissele won't work I think) and a very good upgrade from the stock 15-22 triggers. Just not the best for every use of a 15-22. I use the stock Geissele springs in the Super 3-Gun trigger in my 15-22 and it shows 2.5# on my trigger gauge. No ammo even subsonic Norma TAC-22 has a problem reseting the hammer. I have tried it with a set of JP yellow springs and got a reading of 1.25# and it still worked fine using my usual high velocity ammo. I just decided not to leave them in after 2 months simply because I did not think it was safe enough for match use. Also tried using just the Geissele OEM hammer spring and the JP yellow main spring combo and that did not work at all. And I mean not at all the trigger would jam up when trying to shoot.

I haven't seen the longer pins on their site. Can you point me to them or tell me the model #? I only see the bigger ones for Colt guns.
