I haven't been able to find my question from a Google search,and wen try to use the orange search button on this sight it shuts my phone down, why I don't know but I can't use it. I just want to know witch gas system car v.s mid length is best for running underpowerd ammo. I know It's not best to use cheap ammo, but that's what I can afford to shoot in quantity. I would rather shoot a lot of cheap ammo then a few hundred rounds of mil spec ammo. I am wanting to run a 14.5 inch barrel on my main training upper and was thinking a carbine length gas system would be the most reliable out of the two for the cheap ammo. but don't have any proof of this just a thought. Anyone know of any hard evidence to support this? Or is it just the luck of the draw on weather a gun will run underpowered ammo? Thanks for any help I appreciate it.
