The m4, DI, and piston----no this isn't your usual VS thread.
recently in the remington acr thread, I was called out for not knowing what I'm talking about. :D
This thread isn't about the acr. It's about two identical rifles with one mechanical difference. I'm just trying to understand something specific here. This goes out to the engineers/ subject experts here.
Let's say there are two M4 rifles. Everything about them is EXACTLY the same, except that the second m4 has a short stroke piston instead of the direct impingment gas tube.
The question is, assuming the ONLY difference between the rifles is that one is piston operated, will the piston operated rifle unlock the bolt faster with much force or slower and easier compared to the DI m4?
