Scott,
There's only one A5 buffer spring length for all A5 weights (or they would make this clear on their website).
Quick question...How do you know you need a H2 without having assembled the rifle and shot it?
The A5 is plugged on VLTOR's site as "Marine Corps" but that's just for marketing reasons. I also wouldn't automatically assume the military knows more than aficionado's on forums such as ours. I would pump all available extra money into a normal buffer with an adjustable gas. It'll do the same thing but with less faffing around when you want to change the system for different ammo or a suppressor. With the A5 on back order it will also be quicker.
