I have them in all but one of my AR platforms. I run the light springs as I like that weight. The break and reset is impressive, it's very clean and fast. Which some might like, some might not, in which case, put the heavier weight springs in and use less index/trigger finger than you would on a stock AR trigger;shoot it like a precision rifle trigger until you get used to the way it breaks. I'm guessing this is what happened to the poster above with the triple fire experience. If you limp grip the pistol grip it's possible to get something similar to a bump fire effect. However, if you grip the pistol grip appropriately, it's easy to get precise single and follow up shots very quickly. I run the 24E and the 24 3G models in my weapons. The difference in the two is a (to me) minute more reset in the 24E than in the 24 3G. If you like a flat bow trigger the 24C is what you should look at, if you like a traditional bow trigger get the 24 3G as its the same as the 24 C just with a traditional trigger bow.
If it's any help, there are also several top 3 gunners that compete with the Hiperfire triggers. I think it's also worth mentioning that the ease of installing and maintaing this trigger group is incredibly easy and you can change trigger weight springs out on the firing line in a matter of a minute with no tools. The hammer strike force is also one of the strong points, you won't have any light strikes using this trigger.
