If that spring is from the most powerful Hatsan, then that would be the maximum safe load for the trigger. Assuming that Hatsan has a safe trigger.
Any idea of what the final force of the stock spring is?Thanks

Using microsaalmos 32 fpe he got from his hatsan I got that the average amount of force between the two forces would be about 213 pounds

Obviously, we will be exceeding "factory force numbers" with our gas ram conversions. Otherwise, we would not get a power increase.Just because that is the "strongest Hatsan spring" does not necessarily mean that it is the "maximum safe load" for the Trigger . . . After all, Hatsan has a "performance target level" for their rifles, not a "maximum performance" effort, when they make them.Dave
If someone can post a dimensioned drawing of the Hatsan trigger I'll have a look at it for things such as the shear strength of the sear and the sear pivot pin.... No guarantees, but it's worth a look....Bob

Someone sounds "POWER HUNGRY". I thought the point of gas spring conversions was to make a smoother shooting gun. I think modifying for the sake of power could just give you a broken gun.
