I'm still learning alot about the AR platform, so forgive me if I'm mis-speaking here.
I thought I read somewhere that alot also depends on the barrel type? like carbine, mid-length and rifle (?). Something to the effect of depending on where the gas block/tube is on the different length of barrels can also contribute to shorrt-stroking depending on the ammo (steel or otherwise). I remember seeing some chart that showed the optimal distance of the gas tube/block from the chamber. But I'm sure the lack of expansion of the steel case in battery lets some gases escape that should otherwise flow down to the gas tube/block.
My brain is swimming from reading up on the stuff over the last month or so, so it's possible I'm way off.
