Been cruising through the videos on YouTube about the AEA hp ss plus and carbine in .30. Not a whole lot of reviews out there yet. Any insight on which you would choose and why would be appreciated. Also I was looking at the spec sheets of carbine td version and noticed bottle can be filled at 4500psi but the gun max operating level is only 3600 psi. So with that being said why wouldn’t I just just stick to the cheaper aluminum bottle version. Am I missing something there?
