Both ran like a champ in the cold with the A5h2. Ironically, the supplied H2 carbine buffer was too much for the extended gas 14.5", but ran like a champ with the A5H2. 13.7" Noveske barrels ( no pig) do the same in the cold as the KAC 14.5". In the summer the difference between the feel of the A5H2 and A5H3 aren't much, so I leave the 2 in unless I knows the cans are staying on for the shoot, then they're A5H4s with Sprinco green to give it some zip back.
Overall, I think the A5 kit helps out reliability and smoothness. It doesn't cycle as snappy as the carbine system, so it may not be for everyone's taste.
