Geissele SSA-E question

[jaybirdritenour2]

Just put a Geissele SSA-E in my new Colt mk18 MOD 0 build and all I can say is wow the trigger pull is nice and very clean break. But the hammer looks a little small and thin. This wont cause any tye of light strikes will it. It doesnt look like it has much weight behind it. The spring is good though. Even my Knights hammer which is the same style has alot more weight to it. I have never heard of this being an issue but I also didnt expect it to be this light and small.

Have no fear, it will be just fine. :D

I love it so far. I cant get over how nice the pull and break is. I was told they all are a bit different in performance even with the exact same model. But I got a good one.:)

I had that same trigger in a .308 build and it functioned flawlessly

Your trigger has full power springs. be happy and worry not, u have one of the finest triggers on the planet.

[jaybirdritenour2]

Just surprised me to the overall size of it. Not what I was expecting I guess. But Im happy with it so far. Cant say enough about the quality of the trigger pull. I have a custom built RRA that I changed the bolt to a LMT enhanced bolt and carrier and I will put a SSA-E in it now also. The only heart part of the rifle left Rock River will be the barrel.

You can rest assured that you have made a good choice and will not have any problems.

I installed an SSA-E in my AR and have not had any misfires or light strikes.

As mentioned earlier Bill uses full power springs in these triggers and they are precision made and will serve you well.

That narrow hammer is much faster, lock time, then a Mil-spec. Enjoy one of the best.

Geisseles are designed to light off pretty much anything. Both mine have so far.

Believe it or not, that hammer will strike the primer with MORE kinetic energy than a std hammer. A lot more.

I love my SSA-E. :)

Interesting. I haven't thought of this before. I assume that is because of the hammer being lighter and moving faster?

Bill actually discussed it in one of his videos. It had to do with the strength of the hammer spring, the narrow profile of the hammer, and the actual shape of the hammer and the rotating energy developed at the tip (which is what impacts the firing pin). The shape of the hammer apparently serves to enhance the energy developed...much like the shape of an actual hammer with all of the mass being in-line with the strike face. He stated in the videos that a std hammer actually hits the firing pin too far down from the top of the hammer and that his hammer overlaps the firing pin head just enough to reliably strike it...creating maximum impact forces with minimal mass.

The way he explained it made perfect sense for me....lemme see if I can find the video on Youtube.....

EDIT:

Starting at 4:20. This video is for the Nat-Match triggers, but the SSA & SSA-E designs came from the NatMatch design.

BOOM. More energy into the firing pin than a stock hammer.

Thanks. Good to know!

KAC hammer -- heavy and relatively slow. David Tubb (many times NRA National Highpower Rifle Champion) won with an SR-25, but he lightened the hammer by cutting out some the internal mass (like a Commander hammer) to cut lock time):

JP hammer for faster lock time (basically a GI hammer with the tail cut off:

Bill's top-of-the-line National Match High Speed hammer is lightened a little more but with some steel in the web to maintain some "Body" to it (like a structural I-beam).

As mentioned above, Bill designed his hammer so the impact is at the end, not hitting the end of the firing pin like you would if you were to hit it with the handle of a hammer.

Recently, I had one installed in my Colt LE6920.

I absolutely love it!
