Geissele SSA vs Schmid vs Milspec Hammer Comparison

- I know this is just one factor. They're not gonna be moving at the same speed. The energy in the spring will theoretically be the same if they are of equal stiffness with similar hammer geometry, but I think the real life performance will vary with weight.
My S&W MP-15R upper in 5.45x39 is virtually inoperable without a heavy hammer spring installed (one was included with the upper, but I initially tried running without it). I haven't tried a coated mil-spec trigger group, but I tend to think the results wouldn't be worth the extra cost.
Any updates on the matter
@@bama2579 Well, I did happen to swap in a coated mil-spec trigger group eventually, but I think my hunch was correct: it didn't change much. This rifle always had a fairly heavy, but crisp, trigger pull with a little bit of over-travel, and it's the same now. However, I think the coating does smooth things out. There is zero grittiness (can't recall if this was a problem for me before, though) and the coating on the face of the trigger has a nice feel to it. So, it's a marginal improvement, but I suspect I could easily have done without making the change.
I don't know how you got from it's more akin to momentum to momentum is all that matters at any speed.
You aren't taking into account that KE = 1/2mv^2, so lighter does not necessarily mean less force. Lighter could mean more energy transfer to the firing pin, if the hammer is moving faster. You'd need to measure the velocity of the hammer at the point of contact to have a better idea if light strikes are a concern.
I have a schmid, and I wanted to feel how hard it hit compared to my other rifle with a milspec, and it gave me a significantly more painful wack on the thumb. That is not a reliably measure either, but it did surprise me because the schmid obviously has less mass than the milspec.
Kinetic energy is not how the measure of how primer is ignited. It's the time pressure curve which is akin to a measure of momentum.
If i were after energy id go right after the spring potential energy.
@@whattheshit4664 That's not entirely correct. If momentum (M x V) was all that mattered, then you could try igniting a primer with a firing pin attached to the front of your car. That would be a ton of momentum regardless of velocity, but if you drove too slowly you'd still have huge momentum without the primer reliably igniting, maybe it would or more like the compound would just get slowly pushed out of the way. I think you might be thinking of impulse (change in force over time), not momentum.
Impulse = delta F/T = delta Momentum
Right back at you with slow moving car with it being a measure of KE
Have you tried a larue mbt-2s trigger
No. I do have a friend that has it. He likes it a lot, bur he doesnt have geissele experience. I do not shoot geissele well.
@@whattheshit4664 I bought the larue 2 stage , I guess I shot a milspec so long I just prefer the milspec
I like hearing stuff like that. I have a couple of different milspec triggers some have almost a radius on the leading edge of the trigger sear surface they have a very nice pull. These are not Schmid, they have Φ on them
@whattheshit4664 I'm not sure what mine our , they are whatever colt was using about 10 years ago. Same here mine were terrible at first but after some rounds they've became nice
Schmid with JP springs enhanced kit. Try it.
Didnt realize this fcg uses standard springs. What's the point of adding these? Lighten weight or ensure ignition?
@@whattheshit4664 Lightens the trigger pull and has been totally reliable on all primers.
Drama king!
