Fairly easy, what is the actual real world difference between the different lengths of gas systems on an everyday usage AR15, when having a 16" barrel.
I want to know the members' experiences with theirs, considering functionality, longevity, and things like that.
What I don't want is just repeated interweb rehashes, no member pissoffs intended.
Thanks, guys. This information is going to be used in a custom build I am having put together for myself.
